NPSInsider tip · Closest paved camp to General Sherman Tree — 4.5 miles. Bear box at every site; rangers will revoke your reservation if food is left out. Sites 100-150 sit creek-side for white-noise sleep.
Near Furnace Creek
NPSInsider tip · Only NPS campground in Death Valley with hookups. Summer (June-Aug) is walk-up only and free — but daytime hits 115°F+; arrive at sunset, leave at sunrise. The Texas Spring overflow loop a quarter-mile up has the only real shade.
