About the Park
Reservoir Beach is a pet-friendly beach area at Arlington Reservoir with a filtered swimming area, bathhouse, playground, picnic pavilion, and ADA accessible paths. Dogs are allowed off-leash during designated morning hours from 6:00-9:00 AM in the off-season, but excluded from June through August. Leashed dogs are permitted at other times outside summer.
infoWhat to Know Before You Go
Reservoir Beach is an off-leash area without full fencing. Make sure your dog has solid recall before letting them loose, and keep an eye on them near any roads or boundaries.
Dogs can enjoy water features here — great for cooling off on hot days. Bring a towel for the car ride home, because your pup will probably get soaked.
Walking trails are available, so you and your dog can enjoy a walk beyond just the off-leash area. Trails are a great option for dogs who enjoy sniffing and exploring at their own pace.
Best of all, Reservoir Beach is completely free to visit — no membership or daily fees required.
backpackWhat to Bring
Fresh water and a bowl
Even parks with water fountains can have them out of service. Bring your own to be safe.
Poop bags
Most parks provide them, but don't rely on it. Always come prepared to clean up after your dog.
A towel
Your dog will likely get wet at the water features. Save your car seats with a quick dry-off.
A folding chair
This park may have limited seating, so a portable chair can make longer visits more comfortable.
A reflective collar or light-up leash
If you visit near dusk, visibility gear helps you keep track of your dog and stay safe.
High-value treats
Useful for practicing recall in a distracting environment and rewarding good social behavior.
Your dog's favorite toy
A familiar toy can help shy dogs feel more comfortable and give them something to focus on.
