Start at parking up Kane Creek Blvd. You'll ride the dirt road for a short bit then bust right onto HyMasa singletrack down to the creek. From there a short jaunt up Amasa Back followed by another right back onto HyMasa. There is great signage to keep you on point. From here it is all sweet singletrack.
HyMasa is a fun 3.1 mile climb with scattered descents. On its own, HyMasa is an excellent romp through pristine Moab singletrack. You'll cross Amasa Back / Cliffhanger a couple of times and will be offered the option to cut out on the Amasa to Captain Ahab Connector, but don't!
