Hi there,
The Acadia Park offers a range of activities such as taking a guided tour given by the park rangers, hike, etc. In the evening, you can even attend a lecture or concert at the park’s amphitheatre.
Moose wander into
Acadia only on rare occasions as their habitat is not on ocean coastline but boggy-wetlands such as the lakes and mountain regions.
Black Flies have the annoying habit of swarming around your head and they can bite and leave you marked with little blood splots so, they are actually worse than mosquitoes. The usually appear mid May and mid June time.
Hope this helps
