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.

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.

Nice views of the lake and a good spring and fall hike that's pretty easy for most.

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.

The Big Burn does have some really nice views along the way. Was very surprised to find water (Johnny's Pond) along the way, but the falls were bone dry at this time of year.

It was a beautiful hike. Little shade at times so wear your 45. It has great views as you hike up to the hill which takes you very close to the water. I had lunch in front of the water and enjoyed every second. I would do it again. PS. There is a fee at entrance. I paid $6. #hikingjunkie

It's was a cool hike...took eagles trail nice n easy...down side is hella cow shit but that didn't bother us, plus side I have a dog and everyone up there were really pet friendly. Bring water and bug spray.

What. A. Workout. This trail is definitely not an easy one. Most of the trail to the falls, which is ohlone wilderness trail, was incline. The entire thing was basically a roller coaster. The difficulty caught me and my dog off guard. Carry lots of water!!! As for the falls, I have seen better but it was still well worth the hike :)

One of the toughest hikes I've done. Started from Del Valle and made it to Murrieta Falls. I would recommend it! be ready for a tough hike, there are sections that are very steep, all my leg muscles were burning but the day was cloudy and cool so it wasn't terrible. The place is well maintained, and it is worth the price, if you start from del valle the park charges 5 dollars each permit.

This was a great hike! We will definitely go again! It took about three hours with two adults and two kids 10 and 13 (we stopped for about thirty minutes to eat lunch by the lake). We went mid May and saw a lot of wild flowers (cattle too).

There is shade in the middle part of the hike (the closer you are to the lake). Take water - we each used about four bottles and it was only mid 70s. There are no bathrooms until about halfway through the hike, so plan accordingly.

Some long hard up hills but I wouldn't do the round about again just stay to left at the fork and make your way to the waterfall instead 5 miles one way I think

On April 30, 2016, we hiked from Del Valle to Sonul for 20 miles. The view on the east of Rose Peak is better than that on the west. The east side also has more shade. The trails are well maintained and clearly marked.

This was a hard hike. A lot of uphill. It was not shaded and would be warm in summer. The view was pretty though, and a nice trail!
