This is some pretty nasty stuff. Everything here is difficult and even the green-rated trails are nothing for beginners. The trail surface is almost completely roots and rocks so getting any speed is difficult. A lot of the boardwalks and bridges are loose/wobbly and some of rotting boards. Many large pot holes filled with mud, especially in the main trail, and the surface is quite loose. It's also quite overgrown in spots and obviously not ridden much as the trails are covered in pine needles. Definitely don't go here if you're looking for a fast-paced ride; it's a slow, very hard grind with little variation. The signage is quite nice on the trails though with full names, maps, and difficulty ratings, as well as the fact that difficult and easy routes are frequently marked when available with signs (however there still are mandatory bridges, drops, etc. that often are very difficult too).
Just on a side note, I did have a few issues even finding the trail head since there are a lot of parking lots around Santa's Village and the directions given aren't very specific. If you're having any issues:
Off of Muskoka Rd. 15 (coming from 118) turn right into the parking lot just after the cabins (and almost directly across the road from the theme park). There is another parking lot further back to the left where you can find the trailhead :)
Hilton Falls, Buckwallow (only really comparable to some of the hard stuff there like Spur Line, Do Drop In, and Weasel)
