Overlook is family-friendly; descent to the lake is steep and may be challenging for young children or those with knee issues; altitude considerations
Hikers note the 1,325 ft gain is a steady climb with exposed sections and frequent wildlife sightings. The overlook route tends to be less crowded than the lake approach, but crowds can still overwhelm during peak season. The trail is well-maintained, though some sections may be poorly marked.
No vehicle reservation is required in 2026. The trail starts at Logan Pass, where a 3-hour parking limit is enforced July 1 β Sept 7, 2026 β enough for the overlook, tight for the full lake descent. Consider the ticketed Logan Pass Shuttle (Recreation.gov).

Stunning hike to the Hidden Lake overlook. The incline is moderate but doable for the elderly and kids. May take a little longer. 2.6 miles round trip. The wildflowers are gorgeous against the backdrop of the mountain peaks. Walking sticks are a nicety for navigating the rocks and uneven steps. Lots of wildlife including mountain goats, squirrels, chipmunks, marmots, and even a bear crossed our path. Highly recommended if you can survive the gauntlet of the parking lot at Logan Pass Visitor Center.

Our first hike at Glacier NP, the Hidden Lake Trail, was an incredible introduction! Even with our 10-month-old, it was a truly beautiful and amazing experience. We even scored a rare stroke of luck, finding immediate parking at Logan Pass on the afternoon of July 4th β pure luck!The panoramic views were absolutely stunning, leaving us breathless. And the abundant wildlife (wild goats, bighorn sheep, a buck, and squirrels) kept our little one entertained throughout.Be ready for a 500-foot elevation gain. Only about 10-15 minutes of the trail is boardwalk; the rest is uphill. Roughly 50% of the hike was covered in slippery snow patches, which felt a bit scary at times. If you're carrying a baby or toddler, we highly recommend trekking poles or snow boots for better traction.Despite the challenging snowy sections, the incredible views and wildlife encounters made every step worthwhile. This trail truly offers a quintessential Glacier National Park experience!
