Rivers must be crossed on the major trails which lead along the Gila River and its forks. The four riverside trails require several crossings per mile. Crossings are often hazardous during the mid-March through late April period. There are places along the East Fork which are privately- owned, and hikers must receive written permission to cross these properties, all shown on the wilderness map. Campers should put their tents on high ground, above the forks or river.
Water sources are generally reliable, including the three forks and the river.
There are springs with potable water along several of the most popular trails. Check with the rangers before you set out to confirm water sources on your route. It is advisable not to immerse your head in hot spring water, or splash water on your head or chest. There is a tiny organism in some of the spring pools which, when inhaled through the nose, may cause serious medical problems. Firewood may be gathered for camp fires, but only that wood which is both dead and down.
