The Living Desert attraction includes the largest G-gauge garden railway in the world. Constructed and operated by volunteers, it has more than 2,300 feet of track. The mainline track is 980 feet long and runs through Old Indio, past the Grand Canyon and along side the mining and logging areas.

Living Desert volunteers also built the world's longest wooden G-scale trestle measuring over 202 feet in length. The entire trestle is constructed from redwood, glued and stapled at all joints. The layout is undergoing additional expansion which will increase its size by 15-25%.
