The "Bar" of Bar Harbor 
At low tide, the namesake of Bar Harbor, a sandbar, reveals itself and is used by kayakers at low tide to easily launch into the harbor or by hikers who wish to explore Bar Island which is part of Acadia National Park, northwest of the Town pier.  The gravel and sandy surface remains somewhat wet at low tide for those who wish to discover the rocks, dig in the sand, and find shells, seaweed, and other organisms that live on the bar through its twice-a-day tidal flow of up to 12 feet.  This natural land bridge is accessible as much as 2 hours before low tide and 2 hours after low tide.  Access to the bar is through Bridge Street, but be aware there is no parking on lower Bridge Street.  Vehicles are allowed onto the bar, but caution is the word for keeping an eye on the tide.
