Visiting With Your Dog

Thornton A. Sullivan Park is a wonderful spot for a morning adventure with your pup, especially if you're looking to break up a routine day in Everett. The waterfront location provides beautiful scenery, and the well-maintained trails give you plenty of options depending on how much exercise your four-legged friend needs. When you arrive, expect a mix of other dog owners on weekends, so if you prefer a quieter experience, visiting on a weekday morning tends to work best.

Parking is convenient right off Silver Lake Road, and there's usually ample space even during moderate traffic times. Bring plenty of water for your dog—more than you think you'll need—along with waste bags and maybe a towel if your pup tends to get wet on the trails. The terrain varies throughout the park, so wear appropriate footwear yourself. Before heading out, do check the posted leash rules and current access restrictions, as these can change seasonally.

What makes this park particularly appealing is how easily it connects to the surrounding area. After your walk, you can stroll over to nearby U-Neek or grab a coffee at Crucible Brewing Company, both of which welcome leashed dogs on their patios. If you're looking to extend your outing, several breweries in the vicinity are also accommodating, making it easy to turn a simple park visit into a full afternoon out.

The trails themselves are the real draw here. They wind through natural areas and along the waterfront, offering genuine escape from urban surroundings. Your dog will appreciate the variety of terrain and smells, and you'll get solid exercise without feeling like you're just walking the same neighborhood block repeatedly. Even on busy weekends, the park's size means you can usually find a quieter stretch if you venture a bit farther from the main entrance.
