Cosmo Dog Park
About
17-Acre Lakefront Dog Park
Cosmo Dog Park is a 17-acre Gilbert city park anchored by a sandy-beach lake - rare for the Sonoran Desert. Two large fenced off-leash dog areas (large dogs + small dogs), washing station, walking paths, and lake shore.
What Kids Can Do
While primarily a dog park, the lake's sandy beach lets kids splash with their dogs in summer. Walking paths loop the park with views of dogs playing. Lake shore for hunting bugs and watching ducks. Picnic tables for snacks. Washing station for dogs (and kids' feet) at the entrance [marked: kids should stay close to parents in off-leash zones - this is a working dog park, not a kid playground].
What's Included
Free day-use. Two large fenced dog areas (sized by dog size), washing station, walking paths, picnic tables.
Experience
Plan 1-2 hours. Almost entirely outdoor - bring sun protection, water, swimsuit/towel if planning lake play. Stroller-friendly paths. Free on-site parking. Open 5:30am-10pm daily.
