I was there the 2nd week of July. There were no closures. Otter Cliff was great and I defintely suggest to bring a piece of carpet to protect your rope. I suggest Open Book. It is a 5.7 & a great climb. The crux is at the top. Also Razor Back is a great climb. South Wall offers many great multi-pitch leads. The rock is very impressive. The shuttle bus is a great way to get around the loop, but bringing all your gear on the bus is a pain. If you are staying at a campsite, I would suggest Blackwoods it is right on the island. Otherwise, try to camp in Bar Harbor where the shuttle bus will pick you right up and bring you to the island. To get a schedule you can go to any Acadia Info Center of go to the Bar Harbor town green where there is a info center there. Also that is the main drop off & pick up spot for all the buses. You can also buy your park pass there ($10). I forgot where I camped the last couple days. I stayed at a few places. Bar Harbor has a few campsites, all about $20/night. No Reservations necessary. I hope I helped. I have to get back to work now.
