P.S. Express offers a variety of fun and interesting guided tours for whale watching and general sightseeing around the Olympic Peninsula and San Juan Islands. Dogs are allowed to go on some of the tours, but only if they already have their doggy sea-legs. Dogs must be boat and marine-life comfortable as sometimes the whales are close. There is a $10 additional fee for the dog. Dogs must be well behaved, leashed, and please bring supplies to clean up after your pet.
