On-water distanceAbout 16.3 river milesSwan Falls Dam to Walters Ferry (Birds of Prey)
DifficultyeasyDifficulty follows the cited manager guide where stated and otherwise is deliberately conservative. Current flow, debris, diversions, weather, and party skill can materially change the trip.
ShuttleCar shuttleOne-way shuttle from Walters Ferry back to Swan Falls is required. Allow extra time for the long canyon road approach, wind, and a slow final reach below Celebration Park.
PermitsCheck posted rulesFollow BLM Morley Nelson NCA and Swan Falls site rules, Idaho AIS/PFD requirements, wildlife-closure notices, fire restrictions, and posted dam/private-bank restrictions.
CampingOptions nearbySwan Falls has nearby free camping areas, but the park itself is day-use only. Walters Ferry is day-use; use lawful BLM/NCA campsites or a Boise/Melba-area basecamp and follow fire and wildlife rules.
SeasonJan-DecLate spring through early fall is the normal planning window. Verify snowmelt, releases, fire or fish-protection closures, water temperature, weather, and access status immediately before travel.

  • Safety and land managementCurrent manager notices override this record

    The BLM describes two Class II rapids between Swan Falls and Celebration Park; this is not a beginner-only flatwater trip. Wear a PFD, carry a communication plan, and stay clear of the dam and all posted exclusion zones. Swan Falls operations create short-term flow fluctuations. Check the direct 13172500/Idaho Power below-Swan-Falls record, weather and wind, and current dam notices immediately before launching. The route passes through the Morley Nelson Snake River Birds of Prey NCA. Keep distance from nesting cliffs and wildlife, use only developed public launches, and avoid private-bank landings.
