Blacktail Park Boat Ramp is a day-use facility on Ririe Reservoir featuring a modern boat launch with two ramps (recently expanded to alleviate congestion), mooring slips, fishing docks, and ample parking.

The facility includes picnic tables with reservable shelters ($50/day), vault restrooms, and a life jacket loaner station, with daily fees of $5 weekdays/$10 weekends.

Note that the ramp may be temporarily out of service during water releases from Ririe Dam in late summer/early fall.
