The Delmas park is down town San Jose. I stopped by here once, it was a long strip of dirt and trees with not a lot of parking and maybe not the safest place to be in the city if you don't know you way around. I am sure the dogs love it and it gives the people of the neighborhood a place to exercise their dogs. Now that we have moved to Santa Cruz, we don't spend much time in San Jose dog parks, besides maybe Butcher Park and Fontana Park.
