Middle Fork Transfer Camp & Trailhead serves as the primary access point for Middle Fork Trail #4001 along the Middle Fork Salmon River, offering toilet facilities, stock holding areas, and a ramp for horse and pack animal access.

The site features long-term parking, several campsites with picnic tables and fire rings in the surrounding trees, making it suitable for both day hikes and backpacking trips into the remote Lemhi Range backcountry.
