About the Park
An electrical substation is an unlikely host for a dog park, but Denny Substation Dog Park is exactly that — an off-leash area on the grounds of Seattle City Light's Denny Substation in the South Lake Union area. Hours run 5:00 AM to 10:00 PM, generous bookends for early-shift and late-night dog owners in the surrounding apartment-dense blocks. The park is free to use. Our records don't document fencing or surface details, so check the enclosure before unhooking the leash, and keep dogs leashed on the approach given the busy streets in this part of town. Seattle's drizzle is more nuisance than obstacle here; the long daily hours make it easy to dodge both rain and rush hour.
infoWhat to Know Before You Go
Denny Substation Dog Park 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.
Best of all, Denny Substation Dog Park 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 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.
