Nordic Mountain is a ski hill, the trails are a mix of single and double track weaving in and out of the ski runs and through wooded areas. Very technical in some spots, other sections are super fast. Climbs can be tough but it is a great mix. Maps are on the website but aren't actual trail maps for the hill, they are the trail for races held here. Trails are marked at the single track entrances for the most part but it can be very confusing weaving in and out.. and watch out or you may end up on a downhill run (unless thats your gig).You can get into the trail system at many points, but I use the single track that heads up next to the wake park.
