Betasso Preserve / Benjamin Loop
Upper Beginner to Intermediate level. Betasso is a quick smooth loop through forested hills, with plenty of tight turns and speedy downhill sections. The climbs and descents alternate enough to allow even a beginner to have a good time on this track. Bikes are not allowed on this trail on Wednesdays and Saturdays. The trail direction alternates monthly, so make sure you read the signs at the trailhead
