The historic Susanvillle Railroad Depot was built by Southern Pacific Railroad in 1927 and is a wonderful historical landmark that marks the cultural heritage of the region. The Depot also serves as the main trailhead for the Bizz Johnson National Recreation Trail which is a converted railroad track that follows the old Fernley and Lassen Branch Line of the Southern Pacific Railroad, winding 25.4 miles from Susanville to Mason Station. For the first 16 miles, the multi-use trail follows the rugged Susan River Canyon and crosses the river 12 times on bridges and trestles and passes through two tunnels. It is also a designated California Watchable Wildlife Site # 34.
Lassen Land and Trails Trust (LLTT) owns and operates the Depot and provides information to visitors about the trail, as well as other services in the local area. The western 3/4 of the building is used as a visitor center and museum. The facility also serves as the office and headquarters for Lassen Land & Trails Trust. The LLTT holds the annual Rails to Trails Festival and Handcar Races at the Depot.
