Stretching from the Maine coast to inland forests and dotted with lakes and marshes, Rachel Carson National Wildlife Refuge welcomes 300,000 nature enthusiasts a year. Exploring miles of trails from dawn to dusk, visitors can observe wildlife and take in the beauty of nature all while honoring the memory of world-renowned marine biologist, author and environmentalist Rachel Carson.
