Very technical. More of a black diamond then blue square at some sections.
Fun but tricky.

Great trail to practice rock crawling skills. Hard work. Can’t imagine how hard it was to build. In my mortal view, would need deep suspension plus mad skills to find flow here.

Think this is the rockiest trail I have ridden, even when compared to Quebec trails in Gatineau Park. Great if you want to learn how to ride rock, but not for the feint of heart. Would rate this more black than blue compared to the other blues at AF

I love the Boundary loop A & B. Great job HAFTA maintaining the trails! What a gem. I'm glad the people above will be staying away from the trails. Why chance to break your kickstand.

5 star trail building. It requires a lot of bike handling skills to get in the flow and make it through. It’s pretty relentless, so be prepared for a rocky ride. Pick your lines wisely.

I think I need to get used to Canadian trails. I found this to be almost unrideable. All endless rock gardens where you don't have any momentum considered to be fun here?

Hi Yoga100,

Momentum can be had on this trail and your next time around will be slightly less "unrideable" Please give it a few more tries before giving up.

Trail Captain report:
Did a little rock work repair today, no need for brush cut-back yet. All else seems good.

Folks, the collection of trails in any trail system are ranked relative to each other.

When visiting a new trail network it’s best to start with the basics and see if they’re like the basics at your home trail network. Every trail network is different. This trail is blue because it’s harder than a green and easier than a black inside this trail network.

Rocks almost the entire length. Much more difficult than other blue trails. Very hard on the bike, peddal strikes and bottom brackets strikes were nearly unavoidable.

I agree with the other comment, this trail is black diamond or double black diamond. Comparable trails anywhere else in the GTA are marked as such. The rocks, roots, and difficult terrain make this a very challenging ride, with parts that require dismounting.

This trail should be black diamond at least. Go for a ride at any trail network within 50km of here and try another blue trail for comparison. An intermediate rider doesn't stand a chance of clearing this kind of trail without dismounting multiple times.

Doesn't quite beat out my favourite AF trail (Strangler) but this might be a close second. Needs a bit more time for rocks to settle in and anchor themselves. This will become a mandatory loop when I'm there. It swings both ways, great in either direction.
