Mountain Biking, Los Angeles
Concierge.com's insider take:
Mountain-biking trails run through the Santa Monica Mountains from Griffith Park to the Pacific. On any given day, you'll see purple-faced actors with washboard abs pumping furiously up canyons as if starring roles were being handed out on the peaks. Check www.labikepaths.com or www.latrails.com for routes. Two of many bike-rental companies are Hollywood Pro Bicycles (323-466-5890) and Spokes 'n Stuff Rental in Santa Monica (310-395-4748).
