Rainey (Big Eddy) Access is the second most popular put-in and most common take-out on the Teton River, featuring a boat ramp, large parking area, vault toilets, and adjacent free Fish and Game campground with fire pits and picnic tables.

The dirt road access can be washboard rough but is passable for 2WD vehicles; avoid GPS directions and instead follow local road signs (turn right on 6000 W at the black mailbox, then north 2 miles to W 2000 N).

This location is ideal for both paddlers and anglers, with approximately 1. 5-2 hour floats downstream to Packsaddle and wildlife viewing opportunities including moose and free-range cattle.
