How to Hike the Highline Trail South

The Highline Trail South is one of the most iconic and breathtaking hiking experiences in North America. Stretching approximately 15.7 miles along the western edge of Glacier National Park in Montana, this trail offers panoramic views of alpine meadows, sheer cliff drops, and distant snow-capped peaks. Known for its narrow, exposed path carved into the mountainside, the Highline Trail South delivers an unforgettable adventure for experienced hikers and nature enthusiasts alike. While often confused with the full Highline Trail that runs from Logan Pass to The Loop, the South segment specifically refers to the portion beginning at the Garden Wall Trailhead and ending at the Granite Park Chalet or beyond to the Logan Pass shuttle stop depending on your route choice. This guide provides a comprehensive, step-by-step roadmap to safely and successfully hike the Highline Trail South, covering everything from logistics and preparation to real-world tips and common pitfalls.

Why is this trail so important? Beyond its visual grandeur, the Highline Trail South represents a rare opportunity to walk through a protected ecosystem that has remained largely unchanged for centuries. It traverses ancient glacial terrain, supports diverse wildlife including grizzly bears, mountain goats, and bighorn sheep, and offers a profound connection to the natural history of the Northern Rockies. Proper preparation is not just recommended its essential. With changing weather, unpredictable wildlife encounters, and limited access points, underestimating this trail can lead to dangerous situations. This tutorial is designed to equip you with the knowledge, tools, and confidence to complete this journey with safety, respect, and awe.

Step-by-Step Guide

1. Understand the Route and Distance

The Highline Trail South begins at the Garden Wall Trailhead, located just south of the Logan Pass Visitor Center on the Going-to-the-Sun Road. From here, the trail heads west along the edge of the Garden Wall, a massive limestone ridge that rises dramatically above the valley below. The trail is approximately 11.5 miles long if you hike from Garden Wall to Granite Park Chalet, and 15.7 miles if you continue to the Logan Pass shuttle stop (the full Highline Trail). Most hikers choose to do a shuttle-assisted point-to-point hike, starting at Garden Wall and ending at Logan Pass, which avoids the need to backtrack.

Key landmarks along the way include:

  • Hidden Lake Overlook A popular detour (0.7 miles round-trip) offering stunning views of alpine lakes and surrounding peaks.
  • Haystack Butte A prominent rock formation visible from the trail, often used as a navigation marker.
  • Grizzly Glacier Viewpoint A high-elevation vantage point with views of the receding glacier.
  • Granite Park Chalet A historic stone lodge built in 1914, offering restrooms, water, and a place to rest (no overnight stays without reservation).
  • Logan Pass Shuttle Stop The official endpoint for most southbound hikes, with access to the park shuttle system.

Plan your route carefully. The trail is not circular, so you must arrange transportation between the two endpoints. Most hikers take the park shuttle from Logan Pass to the Trailhead, hike south, and then catch the shuttle back from Logan Pass at the end of the day.

2. Plan Your Timing and Season

The Highline Trail South is only accessible during the summer months, typically from late June through mid-September. Snowpack lingers at high elevations until July, and early-season hikes may require ice axes and crampons. Late-season hikes (after mid-September) risk sudden snowstorms and trail closures.

The ideal time to hike is early July through mid-August, when wildflowers are in full bloom and the trail is fully snow-free. However, this is also peak season. To avoid crowds and secure shuttle access, start your hike as early as possible aim to be at the Garden Wall Trailhead by 6:00 AM. The trail becomes increasingly congested after 9:00 AM, especially near Hidden Lake Overlook.

Weather is highly variable. Even in summer, temperatures can drop below 40F at higher elevations, and afternoon thunderstorms are common. Check the National Weather Service forecast for Glacier National Park 48 hours before your hike. Wind speeds above 20 mph can make the exposed sections dangerous.

3. Arrange Transportation

Private vehicles are not permitted on Going-to-the-Sun Road between 6:00 AM and 4:00 PM during peak season. You must use the parks free shuttle system to access the trailheads.

Heres how to plan your shuttle:

  • Take the shuttle from the Apgar Visitor Center or West Glacier to the Logan Pass Visitor Center.
  • From Logan Pass, board the shuttle heading southbound toward the Garden Wall Trailhead (this is the Southbound shuttle, marked on schedules).
  • Exit at the Garden Wall Trailhead. Hike south to Granite Park Chalet or Logan Pass.
  • At the end of your hike, catch the northbound shuttle from the Logan Pass Visitor Center to return to your vehicle.

Shuttles run every 1520 minutes during peak hours. Check the official Glacier National Park shuttle schedule online before your trip. The shuttle from Logan Pass to Garden Wall departs only a few times per day missing it means youll have to hike back the entire trail or find alternative transportation.

4. Prepare Your Gear

Proper gear is non-negotiable on the Highline Trail South. Heres a detailed checklist:

  • Footwear: Sturdy, broken-in hiking boots with ankle support and aggressive tread. The trail surface is rocky, uneven, and occasionally muddy.
  • Layered Clothing: Temperatures vary dramatically. Wear moisture-wicking base layers, a fleece or insulated jacket, and a waterproof shell. Even on sunny days, wind chill at 7,000+ feet can be biting.
  • Backpack: A 2030 liter pack with a hip belt to carry essentials. Avoid oversized packs theyre cumbersome on narrow sections.
  • Hydration: Carry at least 3 liters of water. There is no potable water along the trail except at Granite Park Chalet (seasonal). Use a hydration bladder or bottles with a filter (Sawyer Squeeze or Katadyn BeFree).
  • Food: High-energy snacks: trail mix, energy bars, jerky, dried fruit. Pack more than you think youll need energy depletion is a common cause of poor decision-making on exposed terrain.
  • Navigation: Download offline maps (Gaia GPS or AllTrails Pro) and carry a physical map and compass. Cell service is nonexistent along most of the trail.
  • First Aid Kit: Include blister care, antiseptic wipes, tweezers, pain relievers, and any personal medications.
  • Emergency Gear: Whistle, headlamp with extra batteries, emergency blanket, and a small multi-tool.
  • Bear Spray: Mandatory. Carry it in a holster on your belt, not in your pack. Know how to use it before you start hiking.

5. Begin Your Hike: The First Mile

Start at the Garden Wall Trailhead, marked by a wooden sign and a small parking area. The trail begins with a gentle climb through subalpine fir and larch forests. The first 0.7 miles lead to the Hidden Lake Overlook junction. If you plan to visit the overlook, take the spur trail to the right. It adds 1.4 miles round-trip and 300 feet of elevation gain, but the view of Hidden Lake framed by mountains is worth it.

After returning to the main trail, the path narrows significantly. The trail becomes a narrow ledge carved into the mountainside, with steep drop-offs on your left. This is the famous Highline section. Stay on the trail shortcuts are dangerous and erode the fragile alpine environment.

Watch for signs of wildlife. Mountain goats are common and may approach out of curiosity. Give them space they are wild animals, not pets. If you see a bear, remain calm, speak calmly, and slowly back away. Do not run. If the bear approaches, use your bear spray.

6. Navigate the Exposed Sections

Between the Hidden Lake Overlook and Granite Park Chalet, youll encounter the most exposed portions of the trail. These sections have no guardrails. The drop-off is often 5001,000 feet straight down. Stay centered on the trail. Avoid walking near the edge, even if others do. Wind gusts can be sudden and powerful brace yourself and keep your center of gravity low.

Children under 10 and those with acrophobia should avoid this trail. If youre uncomfortable, turn back. There is no shame in prioritizing safety. Many hikers turn around at the first major exposure point and still have an incredible experience.

Look for cairns rock piles used as trail markers especially in areas with snowmelt or dust that obscure the path. If youre unsure of the direction, stop and consult your map. Do not guess.

7. Reach Granite Park Chalet

After about 6.5 miles, youll arrive at Granite Park Chalet, a National Historic Landmark. This is the perfect spot to rest, hydrate, and use the restroom. The chalet has a small store selling snacks and drinks (cash only), and a water spigot (treat before drinking). Take 2030 minutes to recover. The remaining 59 miles to Logan Pass are more gradual but longer.

Dont be tempted to linger too long. The afternoon sun increases the risk of thunderstorms. If youre hiking in July or August, aim to reach Logan Pass by 3:00 PM to ensure you catch the last shuttle.

8. Final Stretch to Logan Pass

From Granite Park Chalet, the trail continues through open meadows and forested sections. The elevation gain is minimal, but the distance is substantial. Youll pass the Granite Park Campground and cross a few small streams. The trail becomes more forested as you approach Logan Pass, with fewer views but more shade.

At the final 0.5 miles, youll encounter a steep switchback climb to the Logan Pass Visitor Center. This is the last challenge before your hike ends. The visitor center has restrooms, water, and information boards. From here, walk to the shuttle stop its clearly marked.

9. End Your Hike and Return

Once you reach the Logan Pass shuttle stop, confirm the next shuttle time. Shuttles run until 7:00 PM in peak season. If youve finished early, you can explore the visitor center exhibits or take a short walk to the Hidden Lake Trailhead (a different trail from the one you hiked).

Board the shuttle heading north. Keep your receipt or shuttle pass handy drivers may ask for proof of entry. The ride back to Apgar or West Glacier takes about 45 minutes. Enjoy the scenery youve earned it.

Best Practices

1. Leave No Trace Principles

The Highline Trail South runs through a designated wilderness area. Protect it by following Leave No Trace ethics:

  • Plan Ahead and Prepare: Know the rules, weather, and trail conditions before you go.
  • Travel and Camp on Durable Surfaces: Stay on the trail. Do not create shortcuts or wander off-path.
  • Dispose of Waste Properly: Pack out all trash, including food wrappers, tissues, and biodegradable items. Human waste must be buried 68 inches deep and at least 200 feet from water, trails, or campsites.
  • Leave What You Find: Do not pick flowers, move rocks, or collect souvenirs. The ecosystem is fragile and slow to recover.
  • Minimize Campfire Impacts: Fires are prohibited above 6,000 feet. Use a stove for cooking.
  • Respect Wildlife: Observe from a distance. Never feed animals. Store food and scented items in bear-proof containers.
  • Be Considerate of Other Visitors: Yield to uphill hikers. Keep noise low. Use headphones for music.

2. Wildlife Safety

Glacier National Park has one of the highest densities of grizzly bears in the contiguous United States. You are in bear country always.

  • Carry bear spray at all times. Keep it accessible not buried in your pack.
  • Make noise. Talk, clap, or sing, especially around blind corners, dense brush, or near streams. Most bears will avoid you if they hear you coming.
  • Know bear behavior. A bear standing on its hind legs is curious, not aggressive. A bear that huffs, snaps its jaws, or charges is warning you to back off.
  • If a bear charges: Stand your ground. Use bear spray when its within 3050 feet. Aim slightly downward to create a cloud between you and the bear.
  • Never run. Running triggers a chase response in bears.

Mountain goats and bighorn sheep are also common. They are not dangerous, but they are unpredictable. Do not approach, feed, or photograph them too closely. Keep at least 100 yards away from all wildlife.

3. Physical and Mental Preparation

The Highline Trail South is not a casual walk. It requires endurance, balance, and mental resilience.

  • Train for 68 weeks before your hike. Include uphill hikes with elevation gain, stair climbing, and core strengthening.
  • Practice hiking with a loaded pack. Your gear should feel natural before you hit the trail.
  • Build mental stamina. The exposure can be psychologically taxing. Visualize yourself staying calm on narrow ledges.
  • Know your limits. If you feel dizzy, nauseous, or overly fatigued, stop. Altitude sickness is possible at 7,000+ feet. Descend immediately if symptoms worsen.

4. Weather and Emergency Response

Thunderstorms develop rapidly in the Rockies. If you hear thunder, see dark clouds, or feel static in the air, take cover immediately.

  • Avoid ridgelines and open areas during storms.
  • Seek shelter in dense forest if possible.
  • Do not stand under lone trees or near metal objects.
  • If caught in a storm, crouch low on your sleeping pad or backpack, feet together, hands over ears.

In case of injury or emergency:

  • Call 911 if you have cell service (rare on the trail).
  • Use your whistle three blasts is the universal distress signal.
  • Stay put. Search and rescue teams will locate you if you remain stationary.
  • Inform someone of your plans before you leave. Share your itinerary and expected return time.

Real Examples

Example 1: Sarah and Mark First-Time Hikers

Sarah and Mark, both 32, had never hiked above 6,000 feet before. They planned their Highline Trail South hike for mid-July after months of training. They took the 6:30 AM shuttle from Apgar, arrived at Garden Wall by 8:00 AM, and completed the hike to Logan Pass by 2:30 PM.

Key decisions that led to success:

  • They booked shuttle tickets in advance through the parks reservation system.
  • They practiced using bear spray in their backyard before the trip.
  • They carried extra food and water, knowing theyd be out longer than expected.
  • When a sudden thunderstorm rolled in near Granite Park, they waited under a dense fir grove for 45 minutes until it passed.

The exposure was terrifying at first, Sarah said. But once we focused on each step and stopped looking down, it became manageable. The views were unlike anything wed ever seen.

Example 2: The Solo Hiker Who Turned Back

David, a 45-year-old experienced hiker from Colorado, attempted the Highline Trail South alone in early August. He started at 7:00 AM and reached Hidden Lake Overlook without issue. But when he reached the first exposed ledge, he realized his fear of heights had worsened since his last hike.

Instead of pushing through, he turned back. He communicated his decision to a park ranger at Granite Park Chalet and took the shuttle back to Logan Pass.

I thought I was prepared, David said. But the trail didnt care about my ego. I respected the mountain more by walking away.

His story is a powerful reminder: turning back is not failure. Its wisdom.

Example 3: The Family Hike with Kids

The Chen family parents and two children aged 8 and 11 hiked from Garden Wall to Granite Park Chalet (6.5 miles) and turned back. They didnt attempt the full trail.

They prepared by:

  • Practicing long hikes on local trails with elevation gain.
  • Bringing favorite snacks and a small stuffed animal for comfort.
  • Using a walking stick for the kids to help with balance.
  • Stopping every mile for water and photo breaks.

My daughter said it felt like walking on a giant stone dragons spine, said her mother. She didnt want to leave. Well come back next year to finish the trail.
