Quite a few very short ups and downs make this really fun to ride in either direction. It's a great way to ascend this trail system since the playful rollers make it much more enjoyable than a normal grind up the hill.
A few of the hills are real lung busters, but the dirt is smooth and tacky, and it's technically not a problem... but aerobically it might be!
You'll mostly be riding right on a ridge with great views in all directions, but be careful of the drop-offs in some short sections.
Near the top you get to some stock ponds and an old dirt road. Continue on the road just a bit to get to Itch, Scratch, or World's Greatest.
