Down East Maine: botanical points of interest.
I know there are gardening forum sites for travelers, but I thought I would post this here because this forum sees a lot of traffic (no pun intended). In July, I will be taking a road trip to 'Down East' Maine (Bar Harbor and vicinity), from NJ. What are some botanical side trips worth taking along the way from Massachusetts and points north?
I know about Arcadia National Park, it us on my list.
Thanks in advance.
