Highline Trail in Late September

Question

Greetings! I’m planning my late September trip to GNP, and Highline Trail is at the top of my list of things to do. I understand the shuttles will not be running, and I’m not confident of comfortably completing the full round-trip in one go. I’m considering doing one half out-and-back one day, and the other half another. Has anyone done this? If so, what are some good turnaround points? Another option is to hitchhike back to my starting point after completing a full one-way hike. Is hitching allowed in the park? Thank you!

Answer

The Highline Trail is one of the most scenic and popular hikes in Glacier National Park, so it's understandable that it's at the top of your list! Late September can be a beautiful time to visit, but as you noted, the shuttle services will not be running, and the weather can be unpredictable. Here's some advice on your options:

If you're considering breaking the hike into two halves, it is a feasible plan, though the trail is long and can be strenuous. It's not uncommon for hikers to do the Highline Trail in segments. Below are some recommended turnaround points:

Granite Park Chalet (4.8 miles one-way): This is a popular spot to turn around, especially if you're not aiming for the full 11.8 miles. It's a great place to stop for a rest, enjoy the views, and head back to your starting point. If you’re not confident in completing the entire trail in one go, this is a good option.
The “Garden Wall” (approximately 7.5 miles one-way): If you're up for a bit more of a challenge, turning around after reaching the Garden Wall offers even more breathtaking views. However, the last section up to this point can be steep and rocky, so keep that in mind if you're planning to hike back the same day.

If you're thinking about hiking the entire trail one-way and then hitching a ride back, it is possible but not officially recommended. While hitchhiking is technically not prohibited in the park, it’s generally not encouraged for safety and logistical reasons. Here are a few considerations:

Hitchhiking: While it might be possible to get a ride, especially during busier months, it’s not guaranteed, and there’s no shuttle service in late September, so the likelihood of getting a ride back may be lower. Moreover, Glacier’s vastness and rugged terrain make hitchhiking less predictable. If you choose this option, be prepared for the possibility of waiting a while.
Other transportation: You might consider arranging a private shuttle ahead of time. Some private companies and outfitters offer shuttle services, even outside of the regular park shuttles' schedule. It’s worth investigating options before your trip to ensure you have a reliable way back after a one-way hike.

Whatever option you choose, be sure to monitor weather conditions closely in late September, as snow and colder temperatures can arrive early in the season. Always carry plenty of water, wear appropriate gear, and check trail conditions at the visitor center before heading out.
