This park is ideal for picnicking, horseback riding, boating, fishing and swimming. Lake Del Valle is located in Central Alameda County, about five miles south of the City of Livermore in the Arroya del Valle. Del Valle Dam and Lake Del Valle are features of the South Bay Aqueduct, which is part of the State Water Project.
Went backpacking here for New Years Weekend. It got very cold at night, which was to be expected, but still very much worth the trip. I started at Del Valle and went all the way to Mission Peak. Definitely get an early start if you want to finish the trail in 2 day/1 night. The hike was very dynamic and the terrain would change dramatically throughout the length of the trip. It was very strenuous, and I cannot wait to do this trail again.
To get backpacking and parking permits, you have to call the park system at least 3 days in advance. However, we did not come across any rangers and were not checked for our permits.
The highlighted loop does not cover Murietta falls. Great hike, definitely a challenging one, no human traffic. All trails map is very helpful, however the markers aren't in all trails so could literally lose the forest for the trails. Watch out for parking the car where they don't close the gate at 4 pm.
Great feeling of being in the mountains. Lost of wildlife to be seen. From first rain in Oct till about April it is a pretty spot with steep hills and green slopes. enough trees to add additional interest. It is busy for first couple of miles but thins out after that. There is a water tower about 3.3 miles in at the top of a hill. That is a great spot for lunch and even a good spot to turn around.
Did this trail a long time ago with a slower hiker friend. The only difference is we added the loop on the end that you see on the map to make it about 10 miles. We did the hike on a dry, mellow Jan day. There's a lot of wildlife present away from summer. We saw deer, a coyote and a lot of different types of waterfowl and hawks and a golden eagle. It's a good, wide trail and a lot of it is lakeside with nice views. We also saw several fish caught from the rental boats that day.
Angelica B. on Del Valle Regional Park Campground Trail
Restrooms with flushing toilets & showers that were surprisingly clean.
Hiking trails close by.
Good camp grounds for large groups.
Dogs are allowed.
No cell phone service what so ever. Not ideal if an emergency were to occur or if you are expecting additional people to meet you at the campsite.
No electric outlets if you want to pump air into an air mattress. You have to come equipped with your own power inverter that plugs into your car's cigarette lighter.
No in & out parking privileges, although I know my friends were able to get back in without having to pay again.
