There are many ways to connect the various segments of Hale Mary's and Satan's Kingdom. This is just one variation but we think this has some of the best flow for each segment and linking the segments up.
Tucked in the middle between Hale Reservations main campus to the north or Powissett St and Satan's Kingdom to the south of Hartford St, "Hale Marys" derives its name from both areas.
While no single tech feature in Mary's or Satan's is super difficult on its own, most features come after a healthy and sometimes steepish climbing effort. Cleaning the whole loop is a worthy accomplishment for any rider. But the nice thing about a every mountain biker is that they come equipped with a hiker. ;-)
Mortals will likely have to ride Mary's and Satan's more than a few times to learn the lines.
