Christmas Tree Loop is a loop off the Lone Cactus Loop
. It is impossible to miss, after mile 4 and plus .6 on Lone Cactus you'll hit an intersection with a Christmas tree looking thing with a bunch of medals, tubes and crap hanging from it.
This is the best Fantasy Island has to offer. If you are going to ride Lone Cactus Loop
, ride this loop too. It is not that long. It's fast, cruisey with a couple features and small jumps. I typically ride this multiple times, because it's so good.
It isn't a major workout or anything, just a ton of fun. Enjoy, and watch out for the 'ole cacti.
