I’ve not ridden it yet, but I was up there on the road bike this weekend so it gave me a chance to have a look at what has been done. I very much doubt there are rocky drop offs etc from what I saw. I’m going to go ride it but only when I’m staying up there and doing plenty of other riding in the area. Probably doing it as either a rest day or including it in a bigger ride.
Do you mean 2.5hours driving total there and back or do you mean 2.5hours just to get there to ride, so a total of 5 hours in the car? I’d have to say that it’s no way it or any trail is worth that amount of driving if it’s just a day trip. That’s a days driving with a few hours biking thrown in to make you feel good about yourself.
