The town of Prospect, Maine is great for a visit to Fort Knox, which is one of the best-preserved military fortifications on the coast of New England. Fort Knox is Maine's largest historic fort, and it is also located on the western bank of the Penobscot River.

Fort Knox was built between 1844 and 1869, and the fort was built completely out of granite. The fort was built because Maine was having border issues with British Canada, and during both the American Revolution and the War of 1812, the area of land between Castine and Bangor was invaded and occupied by the British. Fort Knox was built to protect the Penobscot River Valley against a possible British naval invasion but was never fully completed.

Charlotte Rhoades Park & Butterfly Garden

Charlotte Rhoades Park and Butterfly GardenThe Maine Writer. One of my favorite places to visit is located in Southwest Harbor, Maine. The Charlotte Rhoades Park and Butterfly Garden are open seasonally from the middle of April until the middle of October. The park has an information box with brochures for you to take a self-guided tour of the gardens. If you visit on Thursdays from 9:30 A.M. to 11:30 A.M., you will find the garden volunteers at the park that will share information about the gardens and butterfly activities. The garden also has signs with information on the plants and flowers in the garden, along with information on butterflies. The garden beds are meant to look like butterfly wings. There is also a donation box at the entrance to the park, and the suggested donation is $5.00 per family. The park is very family-friendly, although pets are not allowed in the park. This is a great way to spend an afternoon exploring the garden and looking for the butterflies. There are also picnic tables, so you can bring a picnic lunch and enjoy the beautiful views while eating lunch. Just make sure you take your trash back out with you, as there are no trash barrels at the park. The park also has a small swing set for the kids to enjoy. Charlotte Rhoades Park and Butterfly Garden also have an annual butterfly release, which is a fundraiser for the upkeep of the park and activities at the park. To get to the garden, you will need to follow Route 102 on Mount Desert Island through Somesville to Southwest Harbor. Look for the Charlotte Rhoades Park sign on the left. The park is less than half an hour from Acadia National Park.
