The North Tower Loop is a good trail for strong beginners. While there are some decent climbs, the grades aren't too steep. Moderately technical with some rooty and rocky sections, North Tower also features some fast, flowy descents. There are some logs to hop, but each one has a ride-around, so riders aren't forced to cross them.
This loop is fun in both directions, but many riders choose to ride it clockwise. North Tower Loop intersects with Aynes Loop and the north end of Green Valley Trail. Both intersections are well signed.
