It's up to you if you want to ride a green plated bike there as technically, you need a blue plate and there are many sections of gravel and a tiny bit of pavement (including river road) that you'll have to traverse to connect from one trail to another. I have the full routes in Garmin gpx format if you want. Do you use a Garmin GPS? If yes, shoot me an email at
alongat.gat@gmail.com and I can send your the route files. I'm trying to see if I can ride this weekend as well, happy to ride together in a small group too. Also, one other thing apart from the gravel and roads, there's one gate that needs to be bypassed - it does not lead onto private land, I'm not sure why it's been closed but it got closed during the summer and I've ridden past it dozens of times with no issues. You just need to be prepared to climb up an embankment and get around a tree to bypass the gate. Potentially difficult if you're alone but if you're with someone else, they can help. It's not hugely challenging but the embankment is on an angle and there's been a lot of rain and falling leaves so it will be slippery.
