Answer: Snorkeling from the shore in Maine can be a bit challenging because of the colder waters, but there are still some great spots to explore if you're looking for an adventure. Biddeford Pool, in particular, offers a few opportunities for shore-based snorkeling, especially in areas with rocky shorelines or kelp forests. However, it's important to remember that water temperatures in Maine can be quite cold, even in the summer, so wetsuits are recommended for comfort and safety.
