You go on the best vacations! I think you went to Yellowstone last year? We went there last year too, and this year we are going to Acadia. Great minds think alike!
Here's what I have so far:
Everyone everywhere recommends Diver Ed's, and you do have to reserve in advance.
There is an app called Chimani that has great info on paths in the park. I think it was free.
Biking on the carriage roads also came highly recommended. It looks like there are a few rental places in Bar Harbor.
Hope you have a great trip!
