Trail Ridge Road Events Calendar 2027
Trail Ridge Road is closed to through travel for the winter, and the 2027 driving season will not begin until the park's snow-clearing crews have reopened the high pass — historically in late May. This page gathers the winter programme, the confirmed 2027 dates, and the recurring pattern for the rest of the year. Most summer 2027 dates have not been announced yet, and anything not yet published is flagged as such.
⚠️ Closed now — expected to reopen late May 2027
The road is closed to through travel from mid-October to late May (National Park Service). The exact reopening date is set by the park once snow-clearing is complete and is not yet announced for 2027: the road opened on 30 May in 2025 and on 29 May in 2026. Until then, only the lower approaches are open — east to Many Parks Curve, west from Grand Lake to the Colorado River Trailhead. Timed entry is not required in winter. Check the recorded status line at (970) 586-1222.
