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.

This place is beautiful, especially if you come during winter / spring when everything is still green. Very peaceful and serene.

There is a trail where dogs are allowed to walk off-leash. Our dogs loved it.

You can also do water activities here like canoeing, rowing, and fishing.

Challenging and beautiful trail! It’s was a chilly day with morning lows in the high 30’s which made for a pleasant hike. Not too crowded and everything was nice and green. Will definitely do it again!

My friends and I have dubbed this hike "booty blasters" because of the workout your butt gets going up the hill! The view at the top is worth the climb, especially in the Spring. Brought the jogging stroller last time and took the side trail back down the hill. Bad idea! Too narrow!!

Partly cloudy but perfect MLK day hike. Many trail options. Well maintained with benches on hilltops to take a break and enjoy the scenery.
If you make it all the way you the lakeside, be prepared to hoof it back in a steady uphill climb back to the trial head. It’s worth it. Bring water.

Awesome fun and beautiful spot

Great hike. Be prepared for the steep climbs though. The falls at the end is a great pay off!

Ridgeline was a fun a trail to hike, there were plenty of hills and some benches along the way to sit and gaze at the scenic view. Unfortunately while I did enjoy the view the whole area was clearly showing the effects of the drought as a majority of the lake was gone and the rolling green hills had become yellow. Although that might sound disappointing there are some cows along the trail to aw at and the hills are still just as high.

Beautiful, peaceful and challenging. Can’t wait to do it again!

Beautiful but very steep in parts

Great views, but very very steep in spots. My parents had trouble.

Excellent views of east bay. Make sure to hit Rose peak and Murietta falls.

Lots of side trail options. Bring lots of water and sunscreen. Dogs are allowed off leash except in developed parts of the trail (which is only a tiny section along the lake)

Gets the heart beating right from the start. Once at the top, there are more trails. Dogs are allowed off-leash.

Good intense single day hike

One of the most beautiful trail around the bay. It is hard but the climb is pretty regular and you will easily manage the steepness if you are in good physical shape. The fall was dry as expected. We will go back for sure next spring.

Very relaxing, peaceful place with amazing views.
