NO WATER AT CASTLE ROCK TRAIL CAMP

Due to damage to the water system at the Castle Rock Trail Camp, there is no water available at the campground at this time. 

Potable water available is available at the Kirkwood Entrance on Skyline Boulevard (Highway 35) and at Waterman Gap Trail Camp in the southwest corner of the park. Campers at Castle Rock Trail Camp must plan ahead and pack all of the water they we need for their stay before they leave the Kirkwood Entrance.    


We are working to fix the problem as quickly as possible but the system will be out for the foreseeable future.

Thank you for your understanding as we work to fix the problem.
