Even on the warmest summer day, swimming in the chilly water of Puget Sound isn't quite as inviting as just looking at it.

If you are admiring the view near the Edmonds ferry dock, though, don't be surprised to see scuba divers pop out of the water. Clad in wet suits, the divers emerge from the Edmonds Underwater Park, a network of submarine trails maintained by volunteers for more than 30 years.

From the shoreline, all you can see are the bright colored buoys that mark the boundaries of the 27-acre park. Under the surface, divers get an up-close look at sea life as they swim through sunken vessels, concrete blocks and tractor tires.

It's a whole different world down there, Jaclyn Perry told me after a 90-minute dive with her buddy. "It's very peaceful ... You can only hear your own bubbles."

Perry's interest in diving doesn't end with the sport. She starts college in the fall and wants to pursue a career in marine biology. Her dive buddy, Helle Hansen, said she got hooked into diving during a vacation in Guam 20 years ago.

The park is open from 6 a.m. to 11 p.m. See diving regulations on the park's page on the City of Edmonds website.
