TOURS AND WALKS CAN FILL THOSE SUMMER DAYS

If you want to keep a few steps ahead of the summer crowds, you have to know where you’re going and sometimes where you’ve been.

You might think a tour would be the last place for a native to get re-acquainted with his or her own surroundings. How often, though, do you get to run about in tunnel ventilation ducts (well, at least see them), lounge in the Green Room of a theater, or get a socio-cultural perspective on mural art? If you do mingle with some out-of-towners, you might as well do it in grand ostentatious style, like on the back of a fire engine. Here are our suggestions to get out there, and be sure to call ahead.

On the road again: If you get stuck in it, you might as well know what’s behind the walls. The Caldecott Tunnel Tour takes six or more visitors past giant ventilation ducts running above the bores of the Caldecott Tunnel, jet-engine size fans pumping fresh air into the tunnels at more than 50 miles per hour and the crew members who monitor the tunnels from the Control Station. The tour takes two hours, which is about how long the average backup feels like (Free, 9 a.m. Wednesday-Saturday, 510-286-0315).

If you’re looking for a more elevated view, there’s no beating the chance to ride a bright red 1955 Mack fire engine. San Francisco Fire Engine Tours And Adventures either goes through the Presidio and over the Golden Gate Bridge or along Fisherman’s Wharf and through North Beach ($24 general; $12 ages 12 and under, The Cannery, 2801 Leavenworth St. 415-333-7077 or www.fireenginetours.com).

Sweet tooth and suds: Visit the Herman Goelitz Candy Company’s Candyland down Blueberry Lane, over Candy Corn Alley and onto Taffy Avenue in this 45-minute tour of gourmet jelly beans. You even see Jelly Belly Art, namely giant mosaics of famous people and subjects (9 a.m.-5 p.m. daily every 15 minutes, free, 2400 North Watney Way, Fairfield, 707-428-2838, www.jellybelly.com). Get the scoop from cow to cone with the Dreyer’s Grand Ice Cream Factory Tours (appointment only, Monday-Friday, 9:15 and 11:15 a.m. and 2 p.m., $2, 1250 Whipple Road, Union City, 510-471-6622).

Those with a thirst for San Francisco might want San Francisco On Tap: The Beer Lovers Tour. The four-hour tour sensibly drives through the sights and stops long enough for a pub lunch and beer samples at local brew pubs ($72, 415-626-7837).

Going on with the Show: An art deco masterpiece in a time when movie palaces were movie palaces, the Paramount Theatre opens up its velvet curtains for a two-hour behind-the-screen peek (10 a.m. first and third Saturday, $1. 2025 Broadway, Oakland. 510-465-6400, www.paramounttheatre.com).
