I ended up hitting Millstone, it was very cool but if they are looking to promote it they could do a much better job of it. It was not all that easy to find the trail head, we did find Lawsons store fairly easy but the owners seemed surprised anyone was coming to ride the trails and they almost seemed to not know they existed, pretty odd. We actually thought for a bit that we were lost but using the map found the lot by the disk golf area. We tooled around there for a bit, hit a couple of cool bits of single track, passed the first of the air conditioned piles of granite(it was hot as hell so that was pretty amazing to have the temp drop 20 degrees coming down a trail) then headed over to gnome mans land. We realized pretty quickly that the scale on the map is way off. Roller coaster and rock and roll are way longer than they look on the map and vortex, angry gnome and scream'n demon are way shorter. I guess they did this to fit the entire trail system on one page but it kept throwing us off. Gnomes land is pretty awesome, not a bad trail on that side. I am on the fence if this is a destination unto itself, it might be but if you are going to kingdom this is well worth a stop on the way up.
One bit of bad news, its clear someone is vandalizing the ladder bridges. The really cool one built on top of the granite piles after grand lookout climb had the first section pulled off and the second was damaged as well. In other places some of the wood was collapsed or rotted away, that was not clearly vandalism, it seemed to be more wear and tear and age.
There were a lot of people swimming in the quarries, the water in the big ones was crystal clear and blue like the Caribbean.
There were tons of sketchy looking people in and around Barre, that kinda surprised me. The kind that look like the only food they eat is meth.
Thanks to everyone who offered advice and routes. I will do this place again, just need to plan it better or get a guide.
