How to Hike the Highline Trail in Glacier National Park

The Highline Trail in Glacier National Park is one of the most iconic and breathtaking hiking experiences in the entire United States. Carved along the eastern edge of the Continental Divide, this 11.8-mile point-to-point trail offers panoramic views of jagged peaks, alpine meadows bursting with wildflowers, deep glacial valleys, and the ever-present possibility of encountering wildlife such as mountain goats, bighorn sheep, and even grizzly bears. For hikers seeking a blend of physical challenge, natural beauty, and raw wilderness, the Highline Trail is not just a hikeits a pilgrimage through some of the most untouched landscapes on Earth.

Designed in the 1930s by the Civilian Conservation Corps, the trail was originally built to provide access to remote areas for park rangers and to showcase the parks dramatic topography. Today, it attracts tens of thousands of visitors annually, many of whom come specifically to experience its famous skyline sectionwhere the trail clings to the edge of a cliff, offering vertigo-inducing views with nothing but a low stone wall between you and a 1,000-foot drop.

While the trail is considered moderately difficult, its popularity can lead to overcrowding, especially during peak summer months. Without proper preparation, even experienced hikers can find themselves unprepared for sudden weather shifts, limited water sources, or the physical demands of elevation gain and narrow terrain. This guide provides a comprehensive, step-by-step roadmap to safely and successfully hike the Highline Trail, from planning your trip to returning home with unforgettable memories.

Step-by-Step Guide

1. Plan Your Trip During the Optimal Season

The Highline Trail is typically open from late June through mid-September, depending on snowmelt and trail conditions. The most reliable window for hiking is between mid-July and early September, when most snow has cleared from the trail and wildflowers are in full bloom. However, even in July, snow patches can persist in shaded areas, especially near Logan Pass and the Garden Wall.

Avoid hiking in June unless youre experienced with snow travel and equipped with crampons and an ice axe. In September, days grow shorter, temperatures drop, and afternoon thunderstorms become more frequent. Always check the official Glacier National Park website or contact the visitor center for current trail conditions before departure.

2. Choose Your Direction: Logan Pass to The Loop or Vice Versa

The Highline Trail runs between Logan Pass (at the top of the Going-to-the-Sun Road) and The Loop (near the Many Glacier area). Most hikers choose to start at Logan Pass and hike south to The Loop, primarily because:

• It allows you to begin at the highest elevation and hike downhill for the majority of the trail, reducing fatigue.
• The most dramatic cliffside sections are encountered early, when energy levels are highest.
• Shuttle services are available from the Many Glacier area back to Logan Pass, making it a one-way hike without needing a second vehicle.

If you prefer to start at The Loop, youll face a steep 1,700-foot climb to reach Logan Pass, which can be exhausting under the midday sun. However, starting from The Loop offers a quieter trail experience early in the day and is ideal if youre staying in the Many Glacier region.

3. Arrange Transportation

Because the Highline Trail is a point-to-point route, youll need to arrange transportation between the two trailheads. The most common and convenient method is to use the parks free shuttle system.

From Logan Pass: Take the Going-to-the-Sun Road shuttle from the Logan Pass Visitor Center to the Many Glacier area. The shuttle runs hourly during peak season and stops at the Many Glacier Hotel, which is a 0.5-mile walk to the northern trailhead of the Highline Trail.

From The Loop: If you start at The Loop, you can take the shuttle from Many Glacier back to Logan Pass after your hike. Check the current shuttle schedule on the National Park Service website, as times vary by date and weather.

Alternatively, if you have two vehicles, you can leave one at each trailhead. This requires careful coordination and advance planning, as parking at Logan Pass fills by 7:00 a.m. during peak season.

4. Obtain a Going-to-the-Sun Road Shuttle Reservation (If Required)

Starting in 2023, the National Park Service implemented a timed-entry reservation system for the Going-to-the-Sun Road between 6:00 a.m. and 5:00 p.m. from late June through mid-September. This applies to private vehicles and shuttles alike.

Reservations are required to access Logan Pass. You can reserve a spot through the Recreation.gov portal up to 60 days in advance. A limited number of walk-up reservations are available daily, but they are extremely competitive. Book earlyespecially if you plan to hike on weekends.

If youre taking the shuttle, you do not need a separate reservation, but you must arrive at the Logan Pass Visitor Center before the shuttle departs. The first shuttle leaves at 6:00 a.m., and its recommended to be there by 5:30 a.m. to secure a seat.

5. Prepare Your Gear

The Highline Trail is not a casual stroll. It requires thoughtful preparation. Heres a detailed gear checklist:

• Footwear: Sturdy, broken-in hiking boots with ankle support and aggressive tread. The trail includes loose scree, wet rock, and uneven terrain.
• Layers: Weather changes rapidly. Pack a moisture-wicking base layer, a fleece or insulated mid-layer, and a waterproof, windproof shell. Temperatures can drop below 40F even in July.
• Hydration: Carry at least 3 liters of water per person. There are no reliable water sources between Logan Pass and The Loop. A hydration bladder is ideal for easy access.
• Food: Bring high-energy snacks: trail mix, energy bars, jerky, and fruit. Pack a full lunch, as there are no food services on the trail.
• Navigation: Download offline maps via Gaia GPS or AllTrails. Cell service is nonexistent along most of the trail. A physical map and compass are recommended backups.
• First Aid Kit: Include blister care, antiseptic wipes, pain relievers, and any personal medications.
• Bear Spray: Mandatory. Carry it in a holster on your belt, not in your pack. Know how to use it before you begin.
• Hat, Sunglasses, Sunscreen: UV exposure is extreme at high elevations. Even on cloudy days, sunburn is common.
• Trekking Poles: Highly recommended for stability on steep and narrow sections.
• Emergency Shelter: A lightweight emergency bivy or space blanket can be lifesaving in sudden storms.

6. Start Early

Arrive at the Logan Pass Visitor Center no later than 5:30 a.m. This ensures you catch the first shuttle and begin hiking by 7:00 a.m. Starting early provides several advantages:

• Avoids the worst crowdsespecially on the narrow cliffside sections.
• Allows ample time to complete the hike before afternoon thunderstorms roll in.
• Offers the best lighting for photography and wildlife viewing.
• Reduces the risk of heat exhaustion on exposed sections of the trail.

Even in July, temperatures at Logan Pass hover around 45F at sunrise. Dress warmly until you warm up from hiking.

7. Navigate the Trail Sections

The Highline Trail is divided into four distinct sections. Understanding each helps you pace yourself and anticipate challenges.

Section 1: Logan Pass to Hidden Lake Overlook (0.7 miles)

This initial stretch is steep and paved, leading to the popular Hidden Lake Overlook. While crowded, this section offers your first sweeping views of the park. Take a moment here to admire the view, but dont linger too long if youre trying to avoid crowds. After the overlook, the trail descends slightly and begins to turn south along the Garden Wall.

Section 2: The Skyline (1.5 miles)

This is the heart of the Highline Trail. The path narrows dramatically, hugging the edge of a cliff with a 1,000-foot drop on the left. A low stone wall provides minimal protection. The trail is well-maintained, but the exposure can be unnerving for those with a fear of heights.

Key tips:

• Stay to the right side of the trail when passing othersthis gives more room on the cliff side.
• Do not stop in the middle of the narrow section to take photos. Move to wider areas like the Garden Wall Viewpoint to pause.
• Keep children and pets close. The trail is not suitable for strollers or dogs.

Wildlife is common here. Mountain goats often graze on the opposite slope. Observe from a distancenever approach or feed them.

Section 3: The Loop to Grinnell Glacier Overlook (5 miles)

After the Skyline, the trail widens and transitions into a more moderate alpine ridge walk. Youll pass through wildflower meadows, cross small streams (in early season), and enjoy uninterrupted views of the Garden Wall and the valleys below.

At approximately mile 7.5, youll reach the junction for the Grinnell Glacier Overlook Trail. This 1.5-mile side trip offers a stunning view of Grinnell Glacier and the surrounding peaks. If youre short on time or energy, skip this detourit adds 3 miles round-trip and 800 feet of elevation gain.

Section 4: Final Descent to The Loop (2.5 miles)

The final stretch is a steady descent through forested terrain, with fewer views but more shade. The trail becomes rocky and root-filled. Watch your footingthis section can be slippery after rain.

At The Loop, youll emerge at a parking area near the Many Glacier Hotel. From here, its a 0.5-mile walk to the shuttle stop or your second vehicle. If youre taking the shuttle, confirm the next departure time and wait in the designated area.

8. Complete Your Hike and Return

Once you reach The Loop, dont rush. Take time to hydrate, eat, and rest. If youre using the shuttle, the ride back to Logan Pass takes about 45 minutes and offers incredible views of the parks eastern side.

After your hike, consider visiting the Many Glacier Hotel for a meal or snack. The historic lodge offers a charming place to reflect on your journey.

Best Practices

1. Respect Wildlife and Maintain Distance

Glacier National Park is home to one of the largest populations of grizzly bears in the contiguous United States. Mountain goats, bighorn sheep, and moose are also common. Never approach, feed, or attempt to photograph wildlife up close.

Keep a minimum distance of 100 yards from bears and wolves, and 25 yards from all other animals. If you encounter a bear on the trail, remain calm, speak calmly, and slowly back away. Do not run. Carry bear spray and know how to deploy it. Practice removing the safety clip and aiming before your hike.

2. Practice Leave No Trace Principles

Preserve the pristine nature of the Highline Trail by following these core principles:

• Carry out all trash, including food wrappers and biodegradable items like apple cores.
• Use established restrooms at trailheads. There are no facilities on the trail.
• Stay on designated trails to prevent erosion and protect fragile alpine vegetation.
• Do not pick flowers or remove rocks or plants.
• Minimize noise. This is a wilderness experiencelet others enjoy the silence.

3. Prepare for Rapid Weather Changes

Mountain weather is unpredictable. Even on a clear morning, thunderstorms can develop by noon. Signs of approaching storms include darkening clouds, distant thunder, and sudden wind shifts.

If a storm approaches:

• Avoid exposed ridges and cliff edgesthey are lightning targets.
• Seek shelter in dense forest if possible.
• Do not stand under isolated trees.
• Remove metal objects (trekking poles, frame packs) and crouch low on your pack if caught in the open.

Temperatures can drop 20F in under an hour. Always carry rain gear, even if the forecast is clear.

4. Pace Yourself and Know Your Limits

The Highline Trail is 11.8 miles with approximately 1,700 feet of elevation gain. While not technically extreme, the exposure and altitude (over 6,600 feet at Logan Pass) can challenge even fit hikers.

Take regular breaksevery 45 to 60 minutes. Hydrate and snack. If you feel dizzy, nauseous, or short of breath, you may be experiencing altitude sickness. Descend immediately and seek medical assistance if symptoms persist.

5. Hike with a Partner

While solo hiking is permitted, its strongly discouraged on the Highline Trail due to its remoteness, exposure, and wildlife risks. Always hike with at least one other person. Inform someone not on the trail of your itinerary and expected return time.

6. Avoid Crowds by Hiking on Weekdays

Weekends and holidays bring the heaviest foot traffic. If possible, plan your hike for a Tuesday through Thursday. Early morning starts on weekdays often mean youll have the Skyline section to yourself.

Real Examples

Example 1: The Solo Hiker Who Was Unprepared

In July 2022, a 32-year-old hiker attempted the Highline Trail alone, starting at The Loop without a reservation or shuttle plan. He underestimated the heat and carried only 1 liter of water. By mile 6, he suffered heat exhaustion and collapsed near the Grinnell Glacier Overlook junction. Park rangers responded after a fellow hiker called for help. He was treated on-site and airlifted to a hospital. He later stated, I thought I could handle it. I didnt realize how quickly the sun burns up here.

Lesson: Always carry enough water, plan transportation, and never hike alone on this trail.

Example 2: The Family Who Made It Work

A family of fourincluding two children aged 9 and 12completed the Highline Trail in August 2023. They booked their Going-to-the-Sun Road reservation 60 days in advance, stayed at the Many Glacier Hotel the night before, and started at Logan Pass at 6:30 a.m. They packed snacks, bear spray, and extra layers. The kids were engaged with wildlife spotting and took breaks every hour. They finished by 3:00 p.m. and took the shuttle back. It was the most beautiful thing weve ever done, said the mother. The kids still talk about the mountain goats.

Lesson: With preparation, families can successfully complete this hike. Focus on pacing, hydration, and keeping children motivated.

Example 3: The Photographer Who Captured the Perfect Light

A professional photographer from Colorado hiked the Highline Trail at sunrise in late July. He arrived at Logan Pass at 4:45 a.m., hiked slowly to capture the golden light hitting the Garden Wall, and waited until 9:00 a.m. to photograph the first rays illuminating the cliffs. He carried a lightweight tripod, extra batteries, and a drone (which he used only in permitted zones). His images were featured in National Geographics Best of the Parks issue.

Lesson: Early starts and patience yield the best results. Respect park rules on drone useflying is prohibited in Glacier National Park.
