Here's where to start
Much of the U.S. Forest Service public land in the Mammoth Lakes area and in much of Mono County is closed to recreation through at least Sept. 17 due to extreme fire danger. But there are many exceptions, most notably for much of the land north of Conway Summit. The National Forest there, called the Bridgeport Ranger District of the Humboldt Toiyabe National Forest, is not covered by the closure because it is actually managed from Nevada, not from California – but the HT Forest has implemented some new restrictions on overnight use, put a ban on dispersed camping and more (see below).
In brief, all of the Inyo National Forest is closed, which includes most of the FORESTED AND HIGHER ELEVATION lands between Lone Pine and the Conway Summit area.
North of Conway Summit, however, most of the forested lands are still open for day use hiking and fishing, but not to overnight stays. That said, developed campgrounds on that forest are still open.
