Wetherill Mesa is a seasonal part of the park, so check the current tour schedule before building a day around it. From the park entrance, it is about 15 miles to Wetherill Road, then a winding 12 miles to the pavilion; allow 30 to 45 minutes for that last stretch. Vehicles longer than 25 feet or heavier than 8,000 pounds are not permitted on Wetherill Road. Public restrooms, parking, and a seasonal snack bar with prepackaged food and drinks are at the pavilion, before the walk. Dogs are not allowed on the Long House trail or inside the dwelling.
