High Falls to Seagram Lake

High Falls to Seagram Lake is one of the tougher long hauls in the Squamish backcountry, and it earns every step of its Very Difficult rating. This 28.3 km out-and-back route climbs about 1,682 m to around 1,526 m, so you’re in for a big day, usually close to 11 hours. It’s a serious objective with big views, long forest stretches, and a real “out there” feel once you push past High Falls and head toward Seagram Lake.

The hike starts with steady climbing through forest and rough sections, then opens up into classic Sea to Sky terrain with rock, roots, and some scrambly bits depending on route choice. As you gain elevation toward Seagram Lake, the scenery shifts to more alpine terrain with lakes, open slopes, and wide views of surrounding peaks, especially on clear days. The distance and elevation gain add up, so the second half of the return can feel long, but the high-country sections are the payoff.

Current reports say the approach road is a big factor: if you can’t drive to the 2WD parking and end up walking the gravel between the High Falls exit and the 4x4 lot, that extra road slog is rough and makes the day feel endless. The trail to Seagram Lake itself has been very muddy, with mosquitoes in force, so bring gaiters, poles, and serious bug spray. Hikers also mention wasps on the boulder route between Pendant Lake and the parking lot, so move carefully there. Aim for June to September for the best shot at snow-free travel and longer daylight, and only commit to the full High Falls to Seagram Lake push if you’re fit, experienced, and ready for a long grind.
