I-5 Colonnade Off-Leash Area
I-5 Colonade park is located on a steep slope under the I-5 freeway just north of downtown Seattle. This off-leash area covers .5 acre with several large tiers connected by walkways and some stairs. It has a crushed gravel surface, several benches, and a potable water source at the north entrance. Since the park is located directly under I-5, there is protection from the rain, making it a desirable all-weather experience.
