Depending on the time of year you find yourself in town, and your intended goals, your visit may necessitate different modes of transportation. With many of the nearly 3 million annual visitors arriving in the summer months, getting around town by motor vehicle is a bad idea. Bar Harbor is much, much quieter between October and April.
Driving a large truck or SUV is ill-advised, as parking in Bar Harbor is not suited to such vehicles. On the bright side, bringing less stuff requires befriending of locals, improvisation, and overall a more fun Maine experience.
The central area of Bar Harbor is quite small and easily explored by foot. This includes the shopping and eating establishments on Main St. and Cottage St., as well as the activities at the town pier.
