How the zone system works
The Maroon Bells–Snowmass Wilderness issues permits by zone and night on Recreation.gov. You reserve a zone for each night of your route.
- Tiny capacity
- Weekends go first
The backcountry hot springs. Summer weekends disappear almost immediately.
- Multi-night
- Consecutive zones
Stitching consecutive nights across zones is the real challenge.
- Capitol Peak basecamp
- Sells out
Small, serious and gone fast.
Why cancellations matter more here
Capacity per zone per night is tiny, so one cancelled itinerary can reopen several nights at once.
Many people book on release day “just in case” and abandon it later. Those nights go straight back on Recreation.gov, unannounced. For Four Pass, that’s how most late planners get in.
Practical notes
- Bear canisters are required in much of this wilderness. Group size, dates and zone rules are enforced; check the White River National Forest pages.
- Build your route first, then reserve zones to match. No walk-ins at the hot springs or anywhere else.
- Cancelled nights reappear at any hour. Refreshing several zones by hand is miserable. That’s the case Campsite Ranger was built for: pick a zone and window, get an email when a night opens.

How do Maroon Bells wilderness permits work?
The Maroon Bells–Snowmass Wilderness issues overnight permits by zone and by night on Recreation.gov. You reserve a specific zone for each night of your route, so you build the route first and then reserve zones to match. Group size, dates, and zone rules are enforced, and bear canisters are required in much of this wilderness.
Which Maroon Bells zones are hardest to get?
Conundrum Hot Springs has tiny capacity and enormous demand, and summer weekends disappear almost immediately. The Four Pass Loop zones (Snowmass Lake, Crater Lake, Geneva Lake) require consecutive nights across zones, which makes stitching a full itinerary the real challenge. Capitol Lake, the basecamp for Capitol Peak, is small and sells out.
Can you get a Four Pass Loop permit after release day?
Realistically this is how most late planners get in. Because capacity per zone per night is so small, a single cancelled itinerary can reopen several nights at once, and plenty of release-day 'just in case' bookings get abandoned later. Those nights go straight back on Recreation.gov, unannounced.
