Known hazards
- Tidal currents that can exceed 5 knots in the passes — plan crossings at slack
- Commercial shipping lanes in Haro and Rosario Straits
- 45–55°F water year-round — hypothermia in minutes without a dry suit
- Fog banks that drop visibility to zero in minutes
- Steep chop and whitecaps on exposed crossings
- Many marine-trail islands have no fresh water and no cell service
Water notes
Most marine-trail islands are dry — there is no potable water on sites like Blind, James or Posey. Carry at least a gallon per person per day and know the tide and current predictions for every crossing.
Emergency plan
Monitor VHF Channel 16, carry a PLB or satellite messenger, and file a float plan with a shore contact. The Coast Guard covers these waters but you must be able to call and be found.
Leave No Trace
Use designated Cascadia Marine Trail sites, pack out all trash, use the composting toilets where provided, and give seal haul-outs a wide berth.
