The community atmosphere is a highlight for many. Lisa Benson notes, “Visiting from out of town and loved the park! Lots of fun, friendly dogs (and owners) each time we went.”
Regulars often gather around midday, turning the park into a social hub for both dogs and their people. Janey Rodgers shares, “I always go at 11:30 to about 1:00 and it’s my social safety net. I go 7 days a week and all the dogs are awesome—big, little, small. Great place to meet wonderful dog people and I’ve made many a friend there.”
While the park is appreciated for its welcoming vibe and the chance for dogs to run off-leash, visitors should come prepared. There’s no water source available, so it’s important to bring your own water for your dog, especially on warm days.
Lisa Benson advises, “They don’t provide poop bags or water so be sure to bring both.” Some locals bring water bowls to share, but you’ll need to fill them yourself.
Shade is limited as there are few trees, so on hot summer days it can get sunny. Barbara Viklen suggests, “They do need to plant more trees either inside or around it to offer some shade during the summer.”
