About the Park
The I-5 Colonnade Dog Park is a unique off-leash area under the I-5 freeway in South Lake Union, Seattle, featuring a multi-tiered design with stairs and walkways on a steep slope. It offers protection from rain, crushed gravel surface, and amenities like water and waste bags. Despite freeway noise and some reports of dust and graffiti, it provides an urban adventure space for dogs.
