Lily Lake (RMNP) — Estes Park, Colorado

AddressLily Lake Trailhead, on Highway 7 about 6 miles south of Estes Park, Rocky Mountain National Park, Estes Park, CO 80517 (no street address published by NPS)

HoursOpen year-round; no gated hours published by NPS

PricesNo site fee — RMNP entrance pass required (standard pass $15–$35 per vehicle; RMNP annual pass $70)

Price notesNPS publishes the standard pass as a $15–$35 range and does not break out the 1-day vs 7-day vehicle price on its fees page; a pass is required at all times. Children under 16 do not need an individual pass when entering on foot or bicycle. Lily Lake is reached directly from Highway 7 without passing a main entrance station, but NPS states an entrance fee or pass is still required for Lily Lake. In the 2026 season a standard timed-entry reservation was also required 9am–2pm daily, May 22–Oct 12 ($2 processing fee, Recreation.gov only — not sold at entrance stations or visitor centers); the 2027 schedule had not been published at verification (Nov 2, 2026).

Age notesA flat 0.8-mile packed-gravel loop around the lake with very little grade — the shortest, flattest lake walk in this area — with a fishing pier and picnic tables at the trailhead (COTREX).

Suggested timeAbout 1 hours

AccessibilityColorado's official trails site (COTREX) describes this packed-gravel loop as wheelchair-friendly, with accessible parking, picnic tables, a fishing pier and restrooms at the trailhead; NPS also lists the Lily Lake Trail among trails where electric assistive mobility devices are permitted.
