We love dogs … but the area surrounding Diamond Valley Lake is a wildlife refuge (Southwestern Riverside County Multi-Species Reserve) which legally requires a no dogs policy. Thank you for your understanding.
Diamond Valley Lake (also known as The Diamond), located in Hemet is one of the largest man-made reservoirs in Southern California with a capacity of 800,000 acre feet, 260 ft deep and with over 4,500 surface acres.

An Important Water Resource
Diamond Valley Lake is a drinking water reservoir built, owned and operated by The Metropolitan Water District of Southern California.
This reservoir is an important component to providing water for 18 million Southern Californians, and is a critical lifeline in times of drought.
To protect this resource, no body contact with the water is permitted. However, the Diamond Valley Aquatic Center, located near the entrance to the lake, allows for plenty of fun in the water. The Diamond Valley Visitor Center and the Western Science Center, which houses 1 million paleo and archaeo artifacts found during the construction of the Lake, are also located at the entrance to Diamond Valley Lake.
The Lake and the surrounding hills have also become known for the spectacular wildflower blooms each spring, and are popular among hikers. Non-motorized bicycles are also permitted on the Lake View Trail, and equestrians can enjoy the North Hills Trail.
