Located in the San Gabriel Valley, city, Roland Heights, where Azusa Ave and Colima Rd. meet. I was recommended there by another dog lover at Pet Smart. They said it was a dog-friendly park, with its Dali's dog park, which has two separate spaces, one for large groups & the other for smaller groups of dogs. They advised me that there is no one there acting as supervisor, so it's the owner's responsibility to watch their dog, I haven't visited that part of the park, so how much of that is true I don't know. If it's true, then I expect no one's enforcing the canine booster shots. So if you're going there, make sure it's safe, take all precautions, there are also so many trails, you could take your dog, that's what I do when I take my dog, she loves it, chasing the squirrels, seeing the other dogs, I recommend it, I did see a coyote there but it was busy with all the rabbits, that were there. That being said just make sure you keep an eye out for any hazards you might encounter. The deeper you go through the trails, the more you start seeing the posted signs, warning of the wildlife you might see, so stay vigilant, if you decide to visit the park, take enough water for both of you, depending on the season we are in and the time you go, it could get little hot with the sun beating down on you, I put sunscreen on to be safe, work on your tan if that's what you're into. So after surviving the coyote attack, while almost fainting from heat stroke, getting bit by a snake, & being hunted by a bear and a couple of Bobcats, oh almost forgot a Bigfoot sighting, after all that we had a blast. All joking aside, it's a nice place to visit. They have tennis courts if you want to improve your game.
