Wild Rose Boat Ramp offers two concrete boat launch ramps with deep protected marinas on the north shore of Henrys Lake near Island Park, Idaho.

The East Marina features a gradually inclined ramp that becomes steeper at depth, while the West Marina has a steeper initial incline that becomes gradual deeper out—both suitable for different trailer backing preferences.

Day-use launching and parking costs $25 ($2 for resort guests), with convenient on-site amenities including a store and bathrooms, plus options for winter ice fishing vehicle access.
