If you’ve ever ridden a well established and mature trail system you’ll quickly realize the amount of history behind the routes. Often trail systems develop and grow over time spawning new routes and discarding old ones. Singletracks recently published an interesting article on trail guide resources specifically around discovering mountain bike trails that are hidden, older, or those that are not as popular. The article details a lot of great mapping resources that can help you find these trails and discover new places to ride. It’s a great read and gets me excited to go explore some trails of my own.
