Blake Island Marine State Park
Are you a boater craving island time? Do you paddle the Puget Sound on your days off? Or are you visiting Seattle and eager to explore Tillicum village and the island or camp overnight but don't have a boat? Argosy cruises is your ticket to the island.
Accessible only by boat, Blake Island offers a change of pace not far from Seattle. In addition to the Argosy Cruises excursions, this destination features blue waters, peaceful trails, driftwood-scattered beaches and views of the city and Mt. Rainier.
Once off the boat, let your boots or bicycle take you down miles of trail to the island's interior, where forest animals and birds make appearances. Or stay near the water and fish, dig for clams in season or go scuba diving. Arriving by human-powered watercraft? Hunker down in one of the Cascadia Marine Trail campsites at the west end of the island for majestic sunsets over the Olympic Mountains.
Whether you're lounging on your vessel, kayaking the Cascadia Marine Trail, or enjoying Tillicum as part of a tour, Blake Island will exceed expectations.
