The cooler temperatures have arrived, so mark your calendar for these twelve outings that are sure to keep you sizzling this holiday season.

1.	Crank it Up! The Midpeninsula Regional Open Space District is hosting a docent-led, eight-mile bike ride on dirt trails to the top of three separate mountains in the Fremont Older Preserve. Local lore, great views, and lots of heavy breathing (Nov. 10). www.openspace.org
2.	Great Balls of Fire: Watch the sky rain stars during the Leonid Meteor Shower—up to fifteen meteors per hour! Some of the best places to watch include Mt. Tam (we suggest Pantoll parking lot) or the Chabot Observatory (Nov. 17). www.chabotspace.org
3.	Win the Wilderness Lottery: The destination is Ostrander Hut: a cozy cabin at 8,500 feet on the edge of a lake in gorgeous Yosemite. Get there by cross-country skis and see the winter moon through the eyes of the wilderness. This popular backcountry beauty fills up fast, so enter the Ostrander Hut lottery soon; the deadline is Nov. 20. www.ostranderhut.com
4.	Turkey Trek: Come out of your turkey coma with the Sierra Club and their Thanksgiving Day hike, happening this year in Briones Regional Park (Nov. 22). www.sanfranciscobay.sierraclub.org
5.	Hendrix and the Turkey Thigh High: Join San Francisco's City Cycle for their annual day-after-Thanksgiving/Jimi Hendrix–birthday celebration road-ride (try saying that five times and fast). Cross the Golden Gate and cruise throughout Marin. Cyclists of all abilities and skill levels are encouraged to participate (Nov. 23). www.citycycle.com
6.	Polar Express: Families and friends will love the festive holiday train that chugs through downtown Santa Cruz. With colorful lights, hot cider, and Mr. and Mrs. Claus making appearances, this is a jolly good jaunt (weekends starting after Thanksgiving). www.roaringcamp.com
7.	Sunset and Starlight: Paddle into the sunset on Tomales Bay with Point Reyes Outdoors. Enjoy warm drinks and locally made desserts on a secluded beach before making your way back over the starlit waters (Saturdays in Nov. and Dec.). www.pointreyesoutdoors.com

9.	Lite-Brite Boats: Check out some the East Bay's finest boats as they float by all aglow in the 31st-annual Lighted Yacht Parade in the Oakland Estuary. Schooners, sailboats, trawlers, and trimarans welcome (Dec. 1, 5:30 p.m., Jack London Square).
10.	Holy Shiitake! Hunt for wild mushrooms on a beautiful Point Reyes hike with a true 'shroom expert from the Bay Area Mycological Society. Smurf sightings not included (Dec. 29). www.bayareamushrooms.org
