Winter Fair
Most of the Park Loop Road closes, and the carriage roads become cross-country ski trails.
Spring Fair
Late arrival. Roads reopen in April, and May is quiet and fresh.
Summer Good
Busy and beautiful. Lobster rolls, tide pools and cool ocean breezes.

The best season. Fall color peaks in early-to-mid October, but expect crowds, including from cruise ships.
