If you're not headed to New York for the North American Champs, or down to San Diego for the 2-Day Mount Laguna event, then maybe a fun day on a new map by Rex is what you are looking for.

How many orienteering maps do we have with a beach? At the Presidio, you have to go down some steep cliffs. Expect controls on the beach here, with lovely views of San Francisco and the bay!

Crown Beach is a picnic park that also attracts visitors to its nature center, as well as windsurfers and parasailing enthusiasts. Adjacent Washington Park has athletic fields, tennis courts, and a (fenced off) dog park. In the middle of the park there's a lagoon that provides some interesting features. Overall, the park is pretty flat.

This event uses another new map from Rex, mapped at a 1:5000 scale to the 2007 ISSOM Sprint Standard.

The White course stays on the paths and will double as a Junior Sprint course. The Yellow course goes off the paths, and will be a Sprint for older juniors and adults, counted in the USOF Sprint Series ( and the BAOC sprint series. The Memory-O will provide an added challenge—orienteering without a map—but you are allowed to go back to the start as often as you want. It will be done like a Score-O—you will take the controls in any order. All the courses will feature standard pin-punching with punch cards.

Driving Directions

From Interstate 880 in downtown Oakland, follow signs for Alameda – Webster Street tube. Webster St drains into it, and there's another entrance at Broadway and 5th St. Bear left onto Constitution Way, which becomes 8th St. At Otis Dr, turn right into the park entrance.

Public Transit

From downtown Oakland 12th or 19th St BART, take the AC Transit 51 bus towards Alameda. From the San Francisco Transbay Terminal, the AC Transit O goes the same way. Get off either bus at Webster St and Santa Clara Ave—that's where they turn off of Webster. You need to keep walking on Webster towards the bay, left on Central, right on 8th St, and walk into the park when you get to the Otis Dr intersection.
