Estimated Trail Conditions

Before heading out on your next hike or mountain bike ride, check the estimated trail conditions in the OpenSummit app.

We use recent weather conditions to estimate if the trail is snow-covered, muddy, a little wet, or dry, and we update this every hour. We also offer one-click access to a visual history of precipitation and temperature over the past 24 hours.

The estimated trail conditions are updated every hour via a proprietary algorithm that integrates radar, surface and satellite observations, stream gauge data, climatology, and our in-house weather forecast data system.

Here is an example of the estimated trail conditions for Capitol Lake, Colorado.
