HDCA units can accommodate up to 600 tents in a 100' x 100' area and are available by special reservation boards online through the Jackson Forest Service office, http://www.fs.fed.us/rockymtn/nf/b-t/reservations/specialonline/recreation/HDCAs Reservations must be made 6 months in advance to guarantee desired campground location. 

HDCAs are now available at Fremont Lake, Green River Lakes and Big Sandy Recreation area. They are being considered for Cirque of the Towers and Titcomb Basin areas for next season. Public comment is being accepted on other locations for establishing HDCA sites. 

Visitors must now bring their own water supply, even for extended stays in the backcountry area. Recent studies have indicated that hikers who drink imported water have fewer encounters with bears while on trails. No one knows why. Some researchers speculate the chemical composition of out-of-area water may contain compounds that are less attractive to bears than local water. Bears have a very good sense of smell you know. Signs have been posted throughout local campgrounds warning visitors not to drink the water. 

Special, bear-proof,  10 gallon water backpack tanks are available to rent from local Forest Service offices for hikers planning extended trips into wilderness areas.
