Alice Lake is a Sawtooths favorite, and Craters of the Moon adds stark volcanic terrain. July through September is the most reliable window for high-country access.

Why Idaho rewards hikers who plan ahead

Idaho packs two very different landscapes into one trip: the alpine lakes and sharp peaks of the Sawtooths, and the stark volcanic ground at Craters of the Moon. That contrast is the appeal, but it also means conditions change fast. High-country trails can hold snow late, exposed lava fields offer no shade or water.

What to do, step by step

1. Pick your landscape first: Alice Lake for a classic Sawtooths mountain hike, or Craters of the Moon for an easier walk through volcanic terrain.
2. Time it well — July through September is the most reliable window for high-country access; check current trail, road, and fire conditions before you go.
3. Check whether your trailhead needs a permit or pass, and download maps for offline use, since mountain coverage is patchy.
4. Pack more water than you think you need, plus sun protection, layers for sudden weather, and sturdy shoes for rocky ground.
5. Start early, tell someone your plan and return time, and turn back if weather or daylight starts working against you.
6. Leave no trace: stay on the trail, pack out everything, and give wildlife plenty of space.
