Bass Harbor Lighthouse lies on the tip of Acadia National Park. It is also known as Mount Desert Island. The lighthouse is easy to reach by the road that circles the island and you can park in the parking lot above the lighthouse and walk to it.
I would visit when the tides are very low so you can photograph Bass Harbor Lighthouse from the rocks which are exposed.. The best way would be to hire a boat to photograph Bass Harbor Lighthouse from a different angle than is usually seen.
The sun rises on Bass Harbor Lighthouse from the front left as you see it here in these pictures and as you can see the sun in summer sets on the far side of the lighthouse and is a good candidate for HDR.
