Hike #45: 52 Hike Challenge: Audubon Corkscrew Swamp Sanctuary, Naples. We arrived at the Corkscrew Swamp Sanctuary around 10:15 AM on a Sunday morning and the parking lot was already full. So next time I want to get there when it opens at 7 AM. However, we did have a nice stroll along the 2.5-mile boardwalk and viewed the spectacular Bald Cypress Trees and a lot of wildlife such as two baby alligators, a raccoon and plenty of birds, including anhingas. We were disappointed to see all of the sprawling development on the way to the Sanctuary, however (all the more reason for everyone to support the health of sanctuaries like this one!). Owned and protected by the National Audubon Society, Corkscrew Swamp Sanctuary encompasses 13,000 acres in the heart of the Corkscrew Watershed (part of the Western Everglades) and features the largest remaining virgin bald cypress forest in the world. Distance: 2.5 miles.
