Highline Trail to Grinnell Glacier Overlook

The trail officially begins at the Logan Pass Visitor Center. Parking at Logan Pass is extremely limited, especially during peak season. Many hikers opt to use Glacier National Park's shuttle system, particularly if planning a point-to-point hike ending at The Loop.

No, pets are generally not permitted on trails in Glacier National Park, including the Highline Trail. This regulation helps protect wildlife and ensures a safe experience for all visitors. Service animals are an exception.

The best time to hike this trail is typically from mid-July through early October, after the snow has melted and the trail is fully open. Snow patches can persist well into July, and weather can change rapidly at higher elevations. Always check current trail conditions before heading out.

While there isn't a specific permit required for hiking the Highline Trail itself, you will need to pay the entrance fee for Glacier National Park. Additionally, during peak season, a vehicle reservation may be required to access the Going-to-the-Sun Road, which leads to the Logan Pass trailhead. Check the official Glacier National Park website for the most current regulations on entrance fees and vehicle reservations.

The terrain is varied and challenging. Early sections feature a narrow path, sometimes only six to eight feet wide, hugging cliffs with sheer drop-offs, but cable handholds are installed for safety. You'll encounter a short, steep climb to Haystack Pass. The most challenging part is the side trail to the Grinnell Glacier Overlook, which involves a very steep, rocky ascent of 900-1,000 feet in less than a mile.

This trail offers continuous, jaw-dropping mountain vistas. You'll traverse the Garden Wall, providing panoramic views of peaks like Mt. Cannon, Mt. Oberlin, and Heavens Peak. The highlight is the Grinnell Glacier Overlook, which provides spectacular views of Grinnell Glacier, its glacial lake, Salamander Glacier, Mount Gould, Upper Grinnell Lake, and Lake Josephine.

The trail is known for excellent wildlife viewing opportunities. Hikers frequently spot mountain goats, marmots, and bighorn sheep. Occasionally, bears may also be seen, so it's crucial to carry bear spray and know how to use it.

This trail is rated as 'difficult' due to its significant distance, elevation gain, and challenging terrain, especially the steep climb to the Grinnell Glacier Overlook. It is not recommended for beginner hikers or families with young children. Hikers should be in good physical condition and prepared for a strenuous outing.

Yes, the route primarily follows the Highline Trail. For a portion, it also utilizes sections of the Garden Wall Trail. The spur to the Grinnell Glacier Overlook is a distinct side trail off the main Highline Trail.

Given the trail's length and elevation, essential items include plenty of water, high-energy snacks, layers of clothing (weather can change quickly), rain gear, sun protection (hat, sunglasses, sunscreen), sturdy hiking boots, and bear spray. Trekking poles can be very helpful, especially for the steep descent from the Grinnell Glacier Overlook.

There are no facilities directly on the trail itself. The main amenities, including restrooms and water, are available at the Logan Pass Visitor Center at the trailhead. Plan to carry all necessary supplies for the duration of your hike.
