San Elijo Hills Dog Park in San Marcos, California has separate areas for big and small dogs. It is on a hillside with nice views. The park has water stations, grassy spots, and double gates. However, many visitors feel the areas are small. The park is clean and well-kept, but the steep ground and lack of shade can make it hard for pets and their owners to move around easily.
