Ben - what was your opinion of these trails? Could you compare them to anything else in the central NJ area?
It is very similar to Allaire. The place is almost totally flat. The vegetation is pine trees and low-growing shrubbery. The orange trail is nearly entirely single-track. It was marked just enough that you could follow it. Basically, you just followed the trail. When it came to a dirt road or other type of intersection, there were markers to guide you across. In a few cases I had to look around but managed to find the trail marker within a moment.
The surface of the trail is dead leaves and pine needles. There is nothing technical other than a few downed trees that you could ride around in some cases. I did not see one rock (literally). The trail is beginner, hard-tail, and single-speed friendly. For more advanced riders, just go faster.
By the end, I was really looking for some variation. It was just endless turning and twisting through the trees. Some areas were more densely wooded than others which made the trail more challenging if riding fast. There was one area, about 3/4 through the loop, where I found myself going up a gentle switch-back rise. It was about 1.5-2 minutes of climbing and maybe 50' in elev. change. In other words, the park is crazy flat.
While it is easy enough for beginners, it may be too big of a loop. Beginner riders may not be up for the entire 17-18 miles. Once you are out there, your choices are to keep going ahead or turn around and go back.
