Available at the Presidio Visitor Center, 210 Lincoln Boulevard
Explorer Backpacks turn your Presidio visit into a game-like adventure. Each backpack contains an adventure map and challenge cards that guide you to fun discoveries—unique places, hidden spots, wild creatures, and more—all around the park. It's also packed with tools like a magnifying glass, binoculars, and a compass to help you along the way. There are now two versions available: one for kids and one for teens and grown-ups.
To check out a free backpack, drop in to the Presidio Visitor Center (open daily from 10 am to 5 pm). Reserve one in advance by calling (415) 561-4323. Backpacks must be returned by 4:30 pm.
