Twin Bridges Boat Ramp is a concrete launch facility on the South Fork Snake River at river mile 46. 2, offering access for both motorized and non-motorized boats with restroom facilities and picnic areas available.

The site is located within Twin Bridges Park, a 31-acre Madison County recreation area that provides camping (first-come, first-served at $10/night), shaded picnic tables, and a boat dock for river access.

A $3 expanded amenity fee applies to help maintain facilities along the South Fork corridor.
