Overview

This loop pairs the otherworldly climb up Cinder Cone with a peaceful circuit along Snag Lake. Expect a striking mix of painted volcanic terrain, black lava beds, and a long, quiet shoreline. The full loop is about 12.3 miles total with roughly 2,100 feet of elevation gain. It’s a solid day for fit hikers and a great 1–2 night backpack if you want to linger by the water.

What You'll See and Feel

Underfoot is often loose cinder—think beach sand—which makes both the steep cone and the flats more tiring than the numbers suggest. The payoff is big: panoramic views from the cone’s rim across the Fantastic Lava Beds and colorful dunes, then miles of mellow lakeside walking where crowds thin out fast. Along the shore, watch for geese, deer, and hyperactive chipmunks. On warm days, the west side of Snag Lake offers easy swim entries and even a few sandy pockets; some spots are shallow and silty.

Route Notes and Variations

Most hikers start at the Butte Lake area and tackle Cinder Cone early, then loop south along Snag Lake before closing the circuit through cinder fields. The cone climb is the punchiest section—steep and sandy—but entirely optional if you prefer to skip the summit. If you want extra miles, longer loop variants extend to nearby lakes; if you want less, a shorter ~9-mile version loops the lake without the cone. Be aware that sections on the east/southeast side of Snag Lake can be overgrown, faint, or muddy at times, with occasional downed logs.

Conditions and Crowd Level

You’ll encounter exposed stretches through burn areas with limited shade—bring sun protection and more water than you think you need. Mosquitoes can be intense near the lakes in early summer. Expect more people near the cone and far fewer once you’re contouring Snag Lake.

Best Time to Hike

Generally June through September offers the best footing and access. Earlier season visits can see lingering snow or road closures; late season can be wonderful if you’re prepared for cooler temps and shorter days. For photos and less heat, start early: calm morning water and crisper light flatter both the Painted Dunes and lava beds.

Permits, Camping, and Regulations

Day hikers do not need a permit. Backpackers need a wilderness permit reserved online, with a small admin fee plus a per‑person trip fee for ages 16+. An approved bear-resistant canister is required from mid‑April through late November; hanging food is not allowed. There are no designated backcountry campsites or quotas, but certain lakes/areas are closed to camping and you must camp away from roads and developed areas. Snag Lake’s west/NW shore and the peninsula area are popular for views of the lava beds—arrive early to find a low‑impact site. Always treat water.

Tips

  • Gaiters help keep cinder out of your shoes, and sturdy traction pays off on the cone.
  • Download an offline map and carry a backup; some post‑fire corridors and lakeshore segments have faint tread.
  • If you’re after solitude, push beyond the cone before stopping for breaks—the lakeside stretches are where the quiet begins.

Pros

  • Optional cone summit delivers huge views without committing to a separate hike
  • Quiet, swimmable shoreline on the lake’s west side despite a popular trailhead

Cons

  • Loose cinder “sand” makes miles feel slower and more tiring
  • Faint, overgrown, or muddy sections along the lake can slow navigation
  • Exposed burn areas increase sun and heat; mosquitoes can be heavy in season

Parking

Park at the Butte Lake Day Use/Trailhead area; the Cinder Cone trail starts near the boat ramp.

Caution

Loose cinder footing, exposure in burn areas, and faint/overgrown stretches near Snag Lake demand extra water, sun protection, and offline maps. Mosquitoes can be intense. Overnight trips require a wilderness permit and a bear canister (no food hanging).
