Trail Overview

Route: Logan Pass to Granite Park Chalet

The Highline Trail starts at Logan Pass, the highest point on Going-to-the-Sun Road, and sits atop the Continental Divide. This trail runs along an exposed section of the divide called the Garden Wall, known for its abundance of wildflowers and incredible views of the valley below. The common endpoint for the trail is located at the Granite Park Chalet, which is about 7.5 miles from the trailhead in Logan Pass.

Distance, Difficulty, and Elevation

• Distance: 15 miles round-trip from Logan Pass to Granite Park Chalet.
• Difficulty: Rated moderate to difficult, depending on your fitness level and experience.
• Elevation Gain: 800 feet, with gradual elevation changes over the course of the trail.

This hike is suitable for most people in decent shape, but the narrow, exposed sections may not be for everyone. If you’re unsure, start with a shorter section and see how you feel. 

 

Average Time to Complete the Hike

Expect the full hike to take around 6 to 8 hours, depending on your pace and how many stops you make. Alternatively, many hikers opt to only travel a portion of the trail before turning around. If you’re not up for the full distance, hiking to Haystack Butte, about 3.5 miles in, is a great shorter option. 

The full trail to Granite Park Chalet is 7.5 miles one way (15 miles round trip), while the shorter route to Haystack Butte is 3.5 miles one way (7 miles round trip).

Route: Logan Pass to Haystack Butte

This shorter option takes you about 3.5 miles down the trail and gives you a chance to enjoy the incredible views without committing to the full distance. Haystack Butte is a great place to stop for lunch and head back, making it a 7-mile round trip.

Hiking to Haystack Butte is also a great family-friendly way to enjoy hiking the Highline in Glacier National Park. If you choose to continue hiking past Haystack Butte don't forget to stop and enjoy the view before heading on.

Distance, Difficulty, and Elevation

• Distance: 3.5 miles one-way (7 miles round trip)
• Difficulty: Moderate, but more approachable for beginners or those with less time.
• Elevation Gain: About 800 feet, with a steady but manageable incline.

Average Time to Complete the Hike

The round trip can be completed in about 3 to 4 hours, making it a great half-day hike. You can take your time enjoying the scenery and still be back in time for lunch.

When to Hike the Highline

Choosing the right time to plan your hike is critical as weather and trail conditions can be difficult to predict, so flexibility is key. Even during peak season, there's never a guarantee that trails will be open for countless reasons. Remember to come with a backup plan and be prepared for whatever Mother Nature throws at you!

Best Season for Hiking

The best time to hike the Highline Trail is from July to September when the snow has melted and conditions are safe. Snowpack can linger well into summer, so always check trail conditions before you head out. You can check on Glacier’s official trail status page here as a great resource for up-to-date info.

Even in peak summer, Glacier National Park can surprise you with changing conditions. For instance, in August 2024, Going-to-the-Sun Road was temporarily closed due to an early-season winter storm. Always be prepared for sudden weather shifts, no matter when you visit. 

Best Time of Day to Hike

Morning is still the best time to start a hike in Glacier National Park. Not only will you avoid afternoon storms and heat, but you'll also encounter fewer people on the trail.

In 2026, Glacier National Park introduced new parking limits at Logan Pass to help reduce congestion. Beginning July 1 (weather permitting), parking at Logan Pass is limited to three hours. Parking still fills quickly during peak summer mornings, but the new time-limited system means spaces may open up throughout the day compared to previous years.

If you plan to hike a longer route like the full Highline Trail, the park encourages visitors to use the Going-to-the-Sun Road shuttle system rather than relying on parking at Logan Pass. Note that the shuttle now requires advance tickets — it is no longer a free walk-on service. For detailed shuttle schedules and ticket information, check the Glacier shuttle information page.

Essential Gear and Packing List

Packing the right gear is key to enjoying your time in Glacier National Park and while hiking the Highline Trail. Safety and comfort should always be your top priorities and while you don’t need to carry a lot for a day hike, a few essentials will help you stay comfortable and safe:

• Backpack: A comfortable daypack with a hydration system or enough space for water bottles.
• Water: The Highline Trail can be hot in the summer, and water sources are limited. Bring at least 2-3 liters of water per person.
• Snacks and Meals: High-energy snacks like trail mix, protein bars, and fruit will keep you going. For longer hikes, pack a light lunch to enjoy at a scenic spot.
• Bear Spray: An essential when hiking in bear country you can purchase or rent bear spray before your visit. Check out rentals from Glacier Outfitters.
• Sun Protection: The Highline is rocky and exposed with little to no shade coverage. Be sure to bring a hat, sunscreen, sunglasses, or sunshirts.

Clothing for the Highline Trail

Weather can change quickly in Glacier National Park, especially in high-alpine environments such as Logan Pass, so dressing appropriately is essential. Here’s what you should wear:

• Layers: Start with a non-cotton moisture-wicking base layer and add insulating layers like a fleece or light jacket. Bring a waterproof shell jacket or outer layer in case of sudden rain or snow.
• Footwear: Sturdy trail shoes or hiking boots are crucial. The terrain is rocky and uneven, and proper footwear will help you avoid blisters and ankle injuries.
• Socks: The secret to happy feet is proper socks! Opt for moisture-wicking, breathable materials such as merino wool or synthetic blends.

Remember to always check the weather before you go and adjust your clothing accordingly. You can find current forecasts online here and it's always a good idea to pack for unexpected changes in weather.

Wildlife & Safety Tips

Wildlife viewing is always an exciting part of visiting any National Park and Glacier is no exception. With impressive populations of a variety of wildlife, there's a good chance you'll see something, but it's important to have proper expectations.

Spotting wildlife in Glacier National Park might be a bit more difficult than Yellowstone or Grand Tetons, but the reward is well worth the effort. Don't forget to bring a pair of good binoculars and keep a sharp eye out for bighorn sheep, mountain goats, and bears.

Bear Safety & Wildlife Encounters

Glacier National Park is home to its famous population of grizzly and black bears, and bear safety is crucial at all times when visiting the park. Here are a few beginning guidelines before you head into bear country:

• Carry Bear Spray: Make sure it’s easily accessible (not buried in your backpack) and that you know how to use it. Check out this video from the National Park Service about how to properly use bear spray.
• Hike in Groups: Bears tend to avoid groups of people, so hiking with others is a good precaution. If you’re alone, make noise regularly to avoid surprising a bear.
• Make Noise: Bears prefer to avoid humans, so making your presence known can help keep them away. Keep a conversation going, shout, or clap – anything to avoid surprising a bear (but please don't play music).

Mountain Goats & Bighorn Sheep

It's also important to remember that Glacier National Park is home to more than just bears and that all types of wildlife can be dangerous. While hiking on the Highline there is a good chance you'll see mountain goats or bighorn sheep who frequent the area.

While a mountain goat might not look as threatening as a grizzly bear, it's equally important to give all wildlife an appropriate amount of space. For most wildlife like moose, sheep, goats, and deer you should maintain a distance of 25 yards. If you encounter wildlife such as bears, mountain lions, and wolves you should keep a distance of 100 yards.

Weather Awareness

Weather conditions on the Highline Trail can change rapidly, and it’s important to be prepared for seasonal variations.

- Early Season (June to early July): Snowfields may still be present, especially in shaded areas and higher elevations. Rain is also more frequent during this time, so bring a waterproof jacket and be prepared for slippery trail conditions. Always check trail conditions for snowpack updates here before your hike.
  
- Mid to Late Summer (July to September): While weather tends to be more stable, smoke from wildfires can become a concern, particularly in August and September. Smoke can reduce visibility and affect air quality. Keep an eye on the Air Quality Index and consider postponing your hike if conditions are poor.

By staying weather-aware, you’ll be better equipped for a safe and enjoyable hike on the Highline Trail.

Logistics and Accessibility

It's no secret that Logan Pass is one of the busiest spots in Glacier National Park, and access has changed significantly for 2026. Here's what you need to know before you go.

Vehicle Reservations (2026 Update)

Good news for 2026 visitors: Glacier National Park has eliminated the Going-to-the-Sun Road vehicle reservation system that was in place since 2021. You can now drive to Logan Pass without securing an advance reservation.

However, new congestion management rules have been introduced at Logan Pass. Beginning July 1, 2026 (weather permitting), private vehicles can park at Logan Pass for a maximum of three hours. Overnight parking is not permitted except for backcountry permit holders and guests of Granite Park Chalet.

The three-hour limit is designed for shorter visits — things like the Hidden Lake Overlook, the visitor center, or a brief alpine walk. If you’re planning a longer hike such as the full Highline Trail, the Highline to The Loop, or a trip to Granite Park Chalet, the park encourages you to use the shuttle system instead of parking all day.

How the 2026 Logan Pass Rules Affect Highline Trail Hikers

The most common question we're hearing from 2026 visitors is: can you still hike the full Highline Trail if you can't park all day? The answer is yes — but your logistics look a little different than in past years.

Here are your main options for accessing the Highline Trail under the new rules:

• Take the shuttle to Logan Pass — This is the park's preferred approach for full-day hikes. Advance tickets are required (see shuttle section below).
• Book a guided hike — Guided tours handle transportation logistics for you, so you don't need to worry about parking or shuttle tickets. See the guided hike section below.
• Drive and park for a shorter hike — If you're only going as far as Haystack Butte (7 miles round trip, 3–4 hours), the three-hour parking window may work depending on your pace. Plan accordingly and give yourself a buffer.

Always check the official Glacier National Park website for the most current access rules before your visit, as policies can change between seasons.

Going-to-the-Sun Road Shuttle (2026 Update)

Glacier National Park operates a shuttle system along Going-to-the-Sun Road that provides transportation to Logan Pass. In 2026, the shuttle system changed significantly — here's what you need to know:

• Advance tickets are required — The shuttle is no longer a free walk-on service. You must purchase tickets in advance.
• Express routes to Logan Pass — Shuttles run express routes directly to Logan Pass from both sides of the park.
• West-side departures: Apgar Visitor Center and Lake McDonald Lodge.
• East-side departures: St. Mary Visitor Center and Rising Sun.
• Avalanche is no longer a shuttle stop — If you were planning to combine a Highline hike with Avalanche Lake or Trail of the Cedars, note that Avalanche is no longer accessible via the shuttle system in 2026.

If you plan to hike the full Highline Trail or spend more than a few hours in the Logan Pass area, the shuttle is the recommended option. Check the Glacier shuttle page for current ticket availability and schedules before your trip.
