We easily found street parking. Could be a problem I guess on busy times. I love the soft foam cushion surface. Very colorful and had some "nice modern twist " of old fashioned regular play ground activities. I love that most if not all the children were being watched by parents, grandparents etc. my nephew loved the big slides and rock climbing mountain. I got so much joy from watching all the kids play. Nice seeing them be kids instead of playing video games.

Brought my baby here every day to learn how to walk since it has such a huge padded area. It's handicap accessible. There's a decent amount of shade. Plenty of parking. A water refill. A restroom.

There's a nice playground area, rock climbing walls, a long see-saw, swings, and paved trails to walk. Overall, an excellent park and my kids love going here. The only bad thing is that it is far from Diamond Bar. I wish there were more parks like this one in our area. There's plenty of street parking and the park is surrounded by houses. One more negative is that the bathrooms are locked, so hopefully a homeowner is at the park and can open them for you. Xie Xie!

I love this lake! It's really a hidden gem in Orange County because I have lived in Orange County…read moremy whole life and I did not know this existed until I moved to the city. We love to come here as a family, and do family walks, my son loves to ride his scooter around and I also like just taking a walk around with friends and getting our exercise and catching up with each other! The environment is very clean, beautiful scenery of the water and the trees and flowers, and occasionally we'll do some of the exercise exercises along the way ha ha. I always try to park next to the beach club even though the parking is a little limited there because it's just easier to get in and out. When I park in the shopping center where Starbucks in Ralph's is, it gets a little harder to park and hard to cross the street, especially with a little one. So I recommend parking by the beach club side and then walking from there. And of course, during the holidays, it is all decorated with a Christmas tree and lights and it's very pretty. This is our go to place that we go at least once a week!

Great park in rsm!…read more Playgrounds for ages 5-12, but had smaller slides that can work for toddlers too. Swing set, sand pit area , and lots of grass to run around! I love that it's shaded pretty well with so many trees. Lots of benches to sit. The playground floor is soft and good to walk on. The park is next to the pool, so there are bathrooms there. Need SAMLARC card to use them. The park has soccer and baseball field, volleyball court, tennis courts (need SAMLARC card to access), a gazebo with large grills, (which I believe you can rent through SAMLARC), a walking trail around the park, and several picnic tables with bbqs. Lots of parking and easy to walk to park. I brought my 2.5 year old and kept him busy for long time. Will be coming here again!

Another SAMLARC park that offers a lot of amenities is the Arroyo Vista Park located off of Avenida de Las Banderas in Rancho Santa Margarita. This large park sports a heated Junior Olympic sized pool, multiple athletic fields, tennis courts, a volleyball sand court, playground, lattice covered BBQ and picnic areas, restrooms and lots of parking in their private lot. Please note that the restrooms and pool use are for SAMLARC members and accessible with SAMLARC gate access ID cards only. They were pretty busy this past weekend, but the crowd noise level was still bearable. I can imagine how busy they'll get as the weather warms up even more with summer just around the corner.
