What to Expect

Starting from the tiny bush community of Port Alsworth on the shores of Lake Clark, this trail wastes no time getting vertical. You'll climb through dense boreal forest of spruce and birch before breaking above treeline into alpine tundra, where the wind picks up and the views explode in every direction. The route is relentless — expect a sustained, leg-burning ascent with sections of loose rock and exposed ridgeline near the summit. At the top, you're rewarded with a panorama that justifies every gasping breath: turquoise Lake Clark stretching below, volcanic peaks punctuating the horizon, and glaciers gleaming in the distance. The trail is rough and unmarked in places, so route-finding skills help. This one is built for hikers who want to earn their view the hard way, in one of the most remote national parks in the system.

Safety Advisory

Weather in Southwest Alaska shifts without warning. Rain, fog, and sudden temperature drops at the summit are common even on days that start blue — carry full rain gear and an insulating layer no matter what.

This is prime grizzly bear habitat. Make noise on the trail, carry bear spray accessible on your chest or hip, and know how to use it. Moose encounters are also possible in the forested lower sections.

The upper ridge is exposed with no tree cover or shelter. If thunderstorms or high winds develop, descend below treeline immediately rather than pushing for the top.

Pro Tips

Trail Tip

Port Alsworth is fly-in only — book your bush plane well in advance and confirm weight limits for gear, since you'll want layers, rain protection, and plenty of food for the effort.

Trail Tip

Start early in the morning when winds are typically calmer at the summit and visibility tends to be clearest before afternoon clouds roll in off the lake.

Trail Tip

Once you break treeline, look back frequently — the view of Lake Clark framed by the valley below is arguably more photogenic than the summit panorama itself, and you'll want to catch it in good light.
