Pinnacles in June: what the park service says
June at Pinnacles falls inside the pupping season, so Bear Gulch Cave is fully closed until mid-July to protect its bat colony; check the park's cave-status page, since closures can also follow flooding or rockfalls. By mid-June the summer heat sets in and few flowers remain except in wet or cool years. Carry plenty of water, as much of the park has little shade.
