Visit the Town of Bar Harbor Parking site for updated information (below is from the barharbor.gov site as of 12.2022)

Town Council's Permit and Paid Parking Policy is in effect in specified downtown areas. The Parking Map best illustrates the areas where there are kiosks, meters & signed permit parking.
The Parking rates range from $1.50 per hour to $2.00 per hour with certain high demand areas having 4-hour limits and the other areas with no limits.
All major credit/debit cards are accepted as well as US quarters and Town of Bar Harbor Smart Cards and tokens, but no paper money.
Paid parking will be enforced between the hours of 9 AM to 8 PM, Monday through Saturday and 12 PM to 8 PM on Sunday from May 15 to October 30.
Permit parking areas are designated by signage and will be available for residents, employees, COA students and a few other categories that require certain eligibility factors. Residential permits will automatically renew each season if the applicant choses to select that option. Non-residential, COA, and employee permits are good for one season and should be applied for online. They will be approved by authorized staff and issued electronically by vehicle plate number. Other specialty permits are available, such as contractor, dumpster, boat/trailer, or commercial fishing permits.
There are free 15-minute parking spaces available in three locations downtown.
Free all-day parking may be available on other side streets that are not signed.
