Round Lake Boat Ramp is a primitive, unpaved launch facility located on the south end of Round Lake at Round Lake State Park in Sagle, Idaho, designed for small boats and watercraft.

The ramp is part of a developed recreation area that includes two docks, a sandy beach, and nearby amenities such as 51 campsites (16 with water/electric hookups), restrooms with showers, and a visitor center.

Note that only electric motors are permitted on the lake—gasoline motors are prohibited.
