What sections of the trail are closed again?

I know I asked this earlier but I can't find the thread-

Is it huge sections, or is it still worthwhile to drive an hour to get there? Can you do a full loop (We did like a figure 8 pattern last time of both the top and bottom loops) or do you get turned back at some point?

A friend is coming up from Havertown and we were going to take him to either Nox or Jordan, he hasn't ridden a bike in years, trying to figure out where to go.
