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.

BC Marine Trail, our “sister” trail to the north, has developed a fabulous code of conduct which they have asked us to share. We ask our users to abide by the Leave No Trace philosophy, basically “take only pictures, leave only footprints”, but this goes one step further:

*NEW: We need to track visitations to sites for land managers. If you have been to a site lately, please log your visit.

*Almost all sites are by agreement. Here is the Draft CMT agency agreement which was originally created at the inception of Washington Water Trails. While we have one agreement for all of Washington State Parks, each other entity has a separate agreement tailored to the site. In most cases, the agreements specify that WWTA take care of, and find stewards for each site. Some sites may be voluntarily stewarded by that particular land manager, and for this we are grateful.

Shore, weather, and water conditions are in a constant state of change, and you must check weather, tide and currents on your own. You should also confirm, via personal contact with or calls to government agencies, that the Cascadia Marine Trail sites are still available and that conditions have not changed. You must be careful not to exceed your capabilities and must be prepared to use alternate landing spots in the event that a Cascadia Marine Trail site cannot be reached for some reason. It is your responsibility to learn and understand the proper techniques associated with safe water travel and to fully accept and assume all damages, injury or death that may result from attempting to travel to or between the sites described on the following mapping system.
