spectacular View of Whitehead from Peaks Island with the sun setting over Fort Leavitt Island. A cozy wooden bench for two and a view of a placid ocean scene with the cliffs of Whitehead, the sound of pounding surf in the distance, the smell of the salty sea air and the light fragrance of lilacs along the shore. Peaks Island is a very popular tourist destination for visitors to Portland and Casco Bay in Southern Maine. It's the most populous island any time of the year but balloons in the late spring and summer months.
