All PARTICIPANTS ENGAGING IN SWIM the SNAKE 2021 Events MUST sign a waiver for release of liability.   

  • All paddlers MUST wear a PFD (personal flotation device).

The Paddling/Swimming Course

The course across the river is approximately 0.7 miles long, diagonally. Depending on water levels, water temperature averages 69 degrees, river depth is 60’.  The fastest swimmers usually finish in just under 25 minutes (@ 3 mph) and most swimmers are out of the water within 40 minutes (1.5 mph).  Paddlers can cover this distance in less time and if so choose, may paddle back to the Marina, mindful of boat traffic.

Please reference event map.



For swimmers, you may park at Lyons Ferry State Park. You will need a parking permit from Washington State Parks to avoid a parking ticket. DISCOVER PASSES are $35.00/year or day passes are $10.00/day.

Paddlers can off load their “craft” at the boat launch at the LFM and park near the boneyard at the south end of Marina property. Please do not park in trailer spaces reserved for outboard boats.  A free shuttle (personal vehicle) will be available to ferry swimmers back to the Park to retrieve vehicles following the swim.


The Course

For swimmers and paddlers, boaters are in the channel on both sides of the course to help form a swim lane to assist you with direction. If you have trouble, and drift into the boat line, you can hold on and rest or choose to be picked up.  If you drift THROUGH the boat line you will automatically be picked up.

A log boom protecting the Lyons Ferry Park area must be navigated. Paddlers can paddle around the west end of the log boom and head toward the swimming beach at LFSP.  Swimmers pass either over the top or by swimming underneath.  After you clear the log boom, you will access the open Snake River, careful to maintain a diagonal swim line, easing with the current and swimming to Lyons Ferry Marina.

You will also paddle and/or swim underneath the State Highway 261 Bridge. Special caution is needed to avoid the bridge footings (or abutments).  Volunteers in kayaks, canoes, paddle-boards and small craft will help prevent you from straying into this area.

The finish is near the fishing pad and accessible walkway at Lyons Ferry Marina. You will be able to see markers as guides on the shore.  You will exit the river on the Marina (south) side of the breakwater via a ladder.  Follow directions by the event staff and swim under (not under water!) the catwalk ramp to the ladders on the breakwater.   Remember, this is a river and the shoreline is rocky; you are encouraged to wear water shoes or booties if you are sensitive to walking on a rough shore.  As you exit the water, an official will ask for and verify your flight number and name.   PLEASE provide this information to the check-out Captains.
