Lafayette

This is an awesome little park, with plenty of outdoor activities. You can walk the three mile paved trail that closely follows the shore of the lake, or you can brave the six mile dirt trail that climbs up and down the hills which form a bowl around the reservoir. Although swimming is not permitted, there is a place to rent paddleboats, which can hold four people, and are a great way to chase the ducks around! The reservoir is also a great place to spend a nice afternoon fishing or having a picnic -- there are plenty of tables, and even some great little secluded ones! Be aware, however, that at times it feels like everyone in the East Bay has decided to get their nature fix at the same time. Parking is metered and closely monitored, so bring quarters.
