I Tokes A Lot6 months ago

This is by far the nicest dog park in the area. I live in Riverside and drive out to Chino to take my dog here. The dogs are friendly and so are the parents. Everyone is really responsible with their dogs. There is a big dog section and a small dog section both with tons of space for the dogs to run around without being on top of each other. There is a track around the entire area that I've seen lots of people getting their steps in while their dogs socialize and play. It's clean which is really nice. Benches and picnic tables and water fountains. Plenty of shade for those sunny summer days. For me its worth the 30 min drive and they are open until 9pm I think. Very worthy dog park. Nothing bad to say at all about this park.

A nice park. There was an enclosure for large dogs and another for small dogs. Some mature trees provide shade in both. I visited with my three dogs during the early afternoon on a Thursday, so the park was quiet. We are not from the area and used Google maps to locate this park. The large dog space had a couple of benches and a few obstacles for the pack to enjoy. There was a low jump wall, and an elevated tube. There was a dog bag station, but I did not notice a water station inside the fenced areas for either the big or small dogs. There was a communal station outside the gate entrances. There was a nice shade walking space between the fenced areas. There was a walking path running along the north side of the park and a large open green space to the east. I saw no signs designating it a "dog free" space so the pack and I went there to play fetch. Since we were still the only ones there, we played for about 15 minutes before heading home.

This is a good dog park located within a larger park. While a bit on the smaller side it still has enough room for them to run around and burn off energy. There are two sections one for bigger and one smaller dogs with the rules for both clearly posted. There are agillity obsticals as well as a dog drinking foutain and a few places for people to sit. There are double gates with ample space between them to prevent any enthuiastic pups from easily slipping out when someone opens a door without being noticed proir to opening the secondary door. Well lit in the evening and plenty of cameras in the area for security. Now to awnser some google maps questions and do an over all park review since Ontario's website gives both parks the same name: The dog park is located in the far northwest corner on the gounds of James R. Bryant park that rest between flora and D street off of San Antonio. Parking for the dog park is street parking or if you want a nice walk, the park has a deticated parking lot on the south side that you can enter from D street. That park also contians a basketball court ,baseball dimond, fenced tennis court, outdoor body weight gym equipment, childrens play grounds with swings, benches,and bathrooms (While maintained/checked and locked at closeing the type of stalls used are not built to have doors so keep that in mind). There were grilling pits at that park at one time but were removed not long ago. Some people have mentioned the homeless there. They tend to stay to themselves, this location is not that far from downtown ontario,the fire department/city hall. Meaning the area is patrolled regularly and if one has serious problem and has to call emergcy services the police responce is usually pretty swift given how many children /families visit the park day to day. I had a neigbor that had to do so a while back and the respoce was both prompt and the situation was resolved peacfully.

Great pond and small lake. Trout is the current fish. The park is nice and kept up pretty well and the playground is nice too. There is a HUGE eye sore of a little Waterpark that is laughable and dirty. Should tear it out, make it a bass pond and the revenue will pour in more over the water park/pool thing is bringing in from, what, 3 years ago. It's dirt. Bad, empty and just a waist....
