Start at birchwood beach parking lot, take beach bypass on the left, have an easy climb for 15 minutes or so, then keep going straight into a really fun downhill. stay straight until the the rail makes a T shape. go right and follow this same trail and take every right turn. you should then end up on Ogden trail, and go left. you end up at a paved road. go up the hill and up to the top of the tourne (at the playground). have a long and fun downhill, until you come out at the same paved road again. then go past the baseball field and stay straight. bear left onto a trail that leads to a bridge. pass a (creepy) meadow and then take the next right. this will take you back to Birchwood.
