From the Blue Mountain website:
Blue Mountain Bike Park is back, offering lift services, new & old challenges and varied terrain for everyone from hardcore downhillers looking to improve their skills to downhill beginners looking to learn and grow! And speaking of improvement, Blue is adding new trails, loops and a unique Progression Drop Zone and Skills Area. Instruction, rentals and race events are also available, making Blue Mountain your one-stop destination for all things mountain biking, all season long!
Blue mountain offers a total of 19 downhill mountain biking trails, opening in May and closing in early November. The trails vary from beginner to expert downhill. If you are a beginner at downhill mountain biking, I would recommend this park, as it has more gradual downhill trails.
