The United States Forest Service maintains a Visitor Center at the campgrounds, offering printed maps of available hiking and nature trails in the area as well as offering information about any questions that visitors may have. The Visitor Center is located across the parking lot from the kitchen and general store (which is run by a private individual and not by the USFS.)
In many cases the Visitor Center will be staffed by highly knowledgeable individuals from the Angeles Volunteer Association or by other volunteers which can answer questions about the flora and fauna of the area as well as answer questions about the history of Crystal Lake.
The hours of operation are posted on the bulletin board located at the front of the Center and if the Forest Ranger or Forestry volunteer has stepped out of the Center for a period of time, a sign is provided to alert visitors of when the person is expected to return to re-open the Center.
A pay telephone is located at the Visitor Center however there the phone may or may not be working due to weather conditions and vandalism. The USFS employees and volunteers usually have radio communications capabilities with medical assistance, rescue, law enforcement, and other agencies in the event a visitor requires assistance however the Visitor Center hours of operation are limited and emergency assistance may not always be available.
There is drinking water located at most of the camp sites within the campground system however there is also water available at the Visitor Center.
