Last Chance Boat Ramp is a concrete block ramp located on the Henrys Fork Snake River in Fremont County, Idaho, serving as both a put-in and take-out point for the 5. 5-mile Box Canyon to Last Chance float section.

The site offers 25+ parking spaces, a portable restroom, and good trailer turnaround capability, with a trail providing wade access along river left.

This location marks the end of a technical section filled with lava boulders and swift rapids, and serves as the gateway to the famous Ranch section downstream.
