Cascadia Marine Trail

This water trail on Puget Sound is a National Recreation Trail and designated one of only 16 National Millennium Trails by the White House.

It was originated by the “two Toms”, Tom Steinburn and Tom Deschner, when they noticed many of their favorites spots were being purchased and so were not available. The goal is to have a put-in or take-out approximately every three hours.

Suitable for day or multi-day trips, the Cascadia Marine Trail (CMT) has grown to 66 campsites and 160 day-use sites. Most of the day-use sites are also good places to launch a non-motorized, beachable boat.

WWTA members receive many benefits, including discounts at shops and classes, exclusive camping on Anderson Island, and the 2014 print-edition Cascadia Marine Trail Guidebook.
