I have always thought we are very lucky to live in the heart of the Borders, with the Tweed Valley trails on out doorstep. The 7 Stanes Glentress and Innerleithen trail centres are a great place for any one to start from. There are many hillside natural trails in the area, most marked on maps but would be ideal for someone to guide a new rider.
When riding the trails, be it trail centre or natural hill trails always follow the Mountain Bike code, and be respectful to other users and wildlife.
