From Highway 24 in Contra Costa County, exit Mount Diablo Boulevard/Acalanes Road/Upper Happy Valley Road. Drive east on Mount Diablo Boulevard (which is south of Hwy 24) about 1 mile, then turn right at the Lafayette Reservoir sign. Stay to the right, drive uphill on the one way street, then bear left, toward day use parking. You can park in metered spaces for up to 2 hours @ $1 per hour, or pay $6 per day to park in the lot. Bring exact change for the automated entrance kiosk to the lot, which is only staffed weekends and holidays.
To avoid the park fees all together, enter the park from the surrounding neighborhood. From downtown Lafayette, take Moraga Road south. Turn right on Campolindo Drive. At the end of Campolindo, make a right onto Paseo Grande. There's side of the road parking at Paseo Grande's cul de sac.) Follow the Rim Trail down to the parking lot to meet up with the rest of the group (about a 20-30 minute hike).
There is no direct public transportation to the reservoir, and nearby BART and bus stops are probably too far from the reservoir for hikers. Cyclists should have no problem riding from the Lafayette BART station.
