My wife drove coming home, but I was still in a lot of discomfort, and after an hour or so we needed a break. Nearing Discovery Bay, on my phone I looked for a park not too far from Highway 4, ideally something I could walk for a bit and stretch out my back. Cornell Park was like a prayer answered! Wide, grassy open spaces, nice, flat walking path, and a generous loop around the park. This was just what I needed! We walked around a few times, it was a quiet, sunny morning in Discovery Bay, and I could feel my back stretching out with each loop. On the rest of the drive back I was a little more comfortable. Cornell is a wonderful city park, and an ideal stopping point returning to the Bay Area from southern Gold Country.

Don't even try to go there on your own cuz there's a gatekeeper who is an ex special force military guy with night vision and all kinds of "stuff" to prevent people from going into the preserve and vandalizing this place. He lives on the property up on the hills not too far from the gated entrance . (The preserve is fenced in with locked gates ) We met up and got on the docent led bus at the Round Valley Regional Park parking lot. There were 18 of us , a naturalist named Kevin who led the tour and two interpretive student aids. Kevin was a great guide because he was energetic, enthusiastic and very knowledgeable about the environment. I could tell he is very passionate and loves nature and the wildlife . We got to see some fairy shrimps in the vernal pools which are endangered species . We also got to see a golden eagle, red tailed hawks, a kestrel, frogs. And of course the highlight for me was the cave art , pictographs. Awwwww it was so awesome to see pictographs inside the wind caves. Could be as old as 10,000 years old. IT was hella windy up there , well which is why there are wIndmills up there. Super super windy and cold. Bundle up if you are signed up on the tour to go up there. It was so awesome to see everything up there and gained new knowledge on biodiversity. Well worth the money. The tour was $40 a person but subject to change so check their website at East Bay Regional Park.

For Alameda County residents it's $30 per person, others pay a bit more. It's about 45 min away from San Leandro to Round Valley Regional Preserve in Brentwood. FREE parking there, 2 pit toilets. Leader Eddie was our guide w/ an assistant. They had a van that the assistant drove, while Eddie rode w/ the 20 paid ppl on the tour in a small shuttle. Bathrooms available at the parking lot at Vasco Caves, some picnic tables too. Hike was from 9am-2pm, there were lots of breaks and stories. We had a 20 min lunch stop. We hiked about 2.25 miles total, a few steep areas, but not hard. Saw some birds, lizards, tadpoles, sheep. Didn't see the fairyshrimp or tiger salamander - bummer. Caves are more like wind caves and not something you can go into. There was a very faint rock art w/ some old stuff & new stuff (graffiti). I'll have to go back maybe in a few years: Dec-March. April might be good for spring wildflowers, though not much when I went on Sun 4/5/09. No hikes in the Summer - too hot. Website here: http://www.ebparks.org/parks/vasco

There are also plenty of animals around the area, which adds to the charm--you can walk around, take in the scenery, and really enjoy being in nature. While there's a lot you can do here, we usually come for the fishing, and it never disappoints. We've consistently had a good experience and always manage to catch something to take home, which makes each visit even more rewarding. Overall, it's a wonderful place whether you're looking to fish, explore, or simply spend time outdoors in a calm and scenic environment.

The small dog park is a long concrete run until you reach turf. The big dog park has a nice concrete trail with benches and plenty of turf and wood chips to run to our hearts desire.

There's also a water hose for the thirsty dogs. The only downside is that sometimes the gate isn't always open in the morning but overall this is our favorite place to run.

This park is special because it recognizes the US veterans. From most poles you walk into, you'll see banners of some veterans. It's really nice because it shows that did so much to serve us. It's not really a big park compared to the ones I usually go to, but it's still a good place to host outdoor parties. It even has a water park. So it's basically like my home park I usually go to except smaller especially how the parking is set up next to the water park. Honestly, it would have been a bonus if the park is bigger, but this is good enough. I really wanted to walk around the park but it's too hot.
