Another top redwood romp lies in Jackson State Demonstration Forest, which offers 77 trails mostly carved for easy to moderate riders. This is big country, with 50,000 acres of woodland land and the majority of singletrack routes in Mendocino are found, linking some 80- and 100-miles of trails through pristine redwood, fir and pine forests. Built in the 1930s by the California Conservation Corps, the Boiler Trail is a moderate jaunt you can easily enjoy both ways, with a mild 154-ft., climb. Along the way, you’ll catch an antique boiler left behind from the logging era. The Condor, Blue Gum and Gunslinger trails are all solid start-ups leading to the only black diamond in the park – Jim’s Trail – a short fuse 700-ft., rapid descent with deep ruts, roots, steep sections and series of jagged turns requiring expert ability. Biker beware; wear a bell.
