Marrowstone Island: Indian Island Park to Fort Flagler

10 nm, difficulty: Sea Kayak IV

Enjoy a "wind run" with ebb current on this 10 nm paddle up the eastern shore of Marrowstone Island, and play in the tidal rapid off Marrowstone Point. The trip is one-way, requiring a shuttle, and wind from the south.

Launch from Indian Island County Park and paddle around the spit to the right. Paddle for 2.8 nm against the beginning ebb current until rounding Liplip Point. One constraint in this trip is fighting both the wind and the ebb to get to Liplip, so allow some time for this and use the usual tactics such as staying close to shore. Leaving the launch is when you'll encounter the most resistance. After Liplip, paddle a 5.3 nm run with the ebb, and a south wind. The beach along this stretch is limited at very high tides. East Beach County Park, approximately  half-way on the trip, is a good lunch spot. It is feasible to make repeated passes playing in the tidal rapids off Marrowstone Point. Container that ship wakes create exciting conditions. Continue  1.7 nm further west to Fort Flagler boat ramp.

  • A south wind is ideal. Southeast winds mean you have quartering seas.
  • If a participant has a problem with boat control, they can paddle into an eddy on the north side of Marrowostone Point.
  • If a participant doesn’t wish to play in the tidal rapid, they can stay in very shallow water hugging the point, then turn left into the eddy and wait it out on the beach.
  • Standing waves seem at their best with an ebb (at station 0.3 nm northeast of Marrowstone Point) between 2.8 and 3.4 knots.
  • In 2020, culverts were removed and a was bridge installed. A survey in 2021 revealed that three feet of tide level using the Oak Bay tide station is required to float a kayak through the channel between Indian and Marrowstone Islands. Slack in the channel lagged Oak Bay by 40 minutes. This channel flows north during flood (or rising tide).

Marrowstone Island: East Beach to Mystery Bay

8.0 nm, difficulty: Sea Kayak III

Paddle from East Beach Park on Marrowstone Island, north around Fort Flagler, and south to Mystery Bay.

  • Bathrooms are available at East Beach, Fort Flagler, and Mystery Bay.
  • A 0 ft tide or greater is required to paddle between Rat Island and Marrowstone Island.
  • It is a 0.7 nm level walk from Mystery Bay to East Beach to retrieve the cars. 

marrowstone point

Launch from Fort Flagler State Park and play in the tidal rapids off Marrowstone Point. Ebb currents seem to be particularly well developed when there is swell coming down the straits or windy conditions. Container that ship wakes create exciting conditions. Standing waves seem at their best with an ebb (at station 0.3 nm northeast of Marrowstone Point) between 2.8 and 3.4 knots.

Marrowstone Point Triple Cross

20.5 nm, Difficulty: Sea Kayak IV/V

This is a double head paddle with a twist! Take advantage of all currents available. Ride an ebb current out from Marrowstone Point to Partridge Point on Whidbey Island. Once tide starts flooding, ride back to Admiralty Head and then cross over to Wilson Point at Port Townsend. Finally, ride the flood current back to Marrowstone Point.

Marrowstone Point to Fort Casey, Admiralty Head

15.09 nm, Difficulty: Sea Kayak IV

Launch from Marrowstone Point and ride an ebb current up to Fort Casey, Admiralty Head. After short break paddle to Ledgewood Beach County Park. Continue down the shoreline of Whidbey Island south to Lagoon Point County Park, and then paddle west to Marrowstone Point.
