Climbing and Jumping

House of Air. Inside a historic former airplane hangar you can jump over and over and over again on massive indoor trampolines with names such as the Matrix and the Colosseum. For the kids, there's The Fort, a supervised space of 15 conjoined trampolines. House of Air is popular for corporate events and birthday parties (for children and adults), so book ahead at least three days. 926 Old Mason St., Presidio, San Francisco, California, 94129. 415/345–9675; www.houseofair.com.

Planet Granite. If climbing city hills isn't providing enough vacation stimulation, head over to Planet Granite, which offers bouldering and roped climbing and an extensive range of climbing structures—all with sweeping bay views. Rates start at $18 for a weekday morning pass, and $22 for an all-day pass, plus shoe and harness rentals ($6). 924 Mason St., Presidio, San Francisco, California, 94129. 415/692–3434; planetgranite.com.
