Permits & Fees
Rocky Mountain National Park has operated a timed-entry permit system during peak season to manage crowding. The Longs Peak Trailhead corridor has a separate reservation system from the main park entry. Requirements and reservation windows change seasonally — check the NPS RMNP website and Recreation.gov well before your trip date for current year requirements.
- Timed-entry permits are separate from backcountry camping permits
- Early-morning Longs Peak climbers starting before the timed-entry window (often before 5–9 AM depending on year) may not need a timed-entry permit — verify the exact window for your season
- Book as early as possible during peak season (July–August); permits release on a rolling advance window on Recreation.gov
Any overnight stay in the RMNP backcountry — including at the Boulderfield campsite (~12,760 ft, the standard high camp for Longs Peak climbers) — requires a backcountry use permit. Advance reservations are available online through Recreation.gov; a portion of permits are held for walk-up availability at the RMNP Backcountry Office.
- Boulderfield camping puts you within 2 miles of the Keyhole for an early alpine start
- Advance reservations open in March for the coming season; book early for July–August dates
- Bear canister required for all food storage at Boulderfield and above
- Leave No Trace principles strictly enforced; pack out all waste
Standard RMNP vehicle entrance fee valid for 7 days. America the Beautiful annual passes cover entrance for all fee-collecting NPS units — an excellent value if you visit multiple parks annually.
- Annual pass pays for itself in 2–3 national park visits
- Fee required on entry to the park, separate from any timed-entry or backcountry permit
Technical climbing on the Diamond (East Face of Longs Peak) requires a special use permit from RMNP in addition to a standard backcountry permit. The Diamond permit is separate, has specific application requirements, and is intended for experienced technical climbers. Contact the RMNP Backcountry Office for current Diamond permit procedures.
Because the Longs Peak timed-entry window typically begins around 5–9 AM (varies by season and year), climbers starting at 2–4 AM can often enter the trailhead before the permit window activates. This is one of the practical advantages of the recommended pre-dawn start time for the Keyhole Route. Always confirm the specific window for your year on the NPS RMNP website — do not rely on prior-year information.
Trailhead & Staging Logistics
| Location | Elevation | Details |
|---|---|---|
| Longs Peak Trailhead | 9,405 ft | Primary trailhead; limited parking; arrives full by 5–6 AM on summer weekends; restrooms and ranger station on site; no overnight parking without permit |
| Boulderfield Campsite | ~12,760 ft | Designated backcountry camp 6 miles from trailhead; standard high camp for summit day alpine starts; bear boxes provided; composting toilets; no fires |
| Estes Park | ~7,522 ft | Full services — lodging, gear resupply, food, and fuel; primary staging town for all RMNP climbs; 10 miles from Longs Peak Trailhead |
| RMNP Backcountry Office | Estes Park | Walk-up permits; ranger conditions info; current route status; located at park visitor center |
The Longs Peak Trailhead parking lot has limited capacity and fills completely by 5–6 AM on summer weekends. Parties planning a 3 AM start should arrive by 2:30 AM to ensure a parking space. If the lot is full, additional parking is available along Highway 7 but adds significant walk time before the climb even begins. Consider lodging in Estes Park the night before to minimize pre-climb travel stress.
Pre-Climb Logistics Checklist
- 1
Verify Current RMNP Permit Requirements
Timed-entry requirements and backcountry permit procedures change by season and year. Check the NPS RMNP website and Recreation.gov 4–6 weeks before your trip for current requirements — do not rely on prior-year guidance.
- 2
Book Boulderfield or Estes Park Lodging Early
If staging a two-day climb with a Boulderfield overnight, book your backcountry permit in March when advance reservations open. If day-climbing, book Estes Park lodging early for peak summer weekends — the town fills quickly.
- 3
Check Current Ranger Conditions
Contact RMNP rangers or check the park website for current Longs Peak conditions — particularly early-season snow on the Homestretch and Trough, rockfall activity, and any route closures. The ranger station at the Longs Peak Trailhead has current information.
- 4
Plan Your Start Time Around the Lightning Window
Leave the trailhead no later than 3 AM — earlier is better. The goal is to summit by 10–11 AM and be back below treeline before afternoon storms develop. Longs Peak has one of the highest lightning fatality rates of any Colorado 14er.
- 5
Leave a Detailed Trip Plan
Leave your complete itinerary — trailhead, route, intended summit time, and expected return — with a contact not on the climb. Let them know when you have returned safely. Cell service is unreliable on the upper mountain.
