The National Trust in Bermuda has wisely protected the island's nature reserves. If you play by the rules -- that is, don't disturb animal life or take plant life as a souvenir -- you can explore many of these natural wonderlands. If you enjoy nature trails, they're one of the most rewarding reasons to visit Bermuda.

The best and largest sanctuary is Spittal Pond Nature Reserve in Smith's Parish. Birders visit the reserve -- especially from September to April -- to see herons, ducks, flamingos, terns, and many migratory fowl (which can't be seen after Mar). This 24 hectare (60-acre) untamed seaside park is always open to the public with no admission charge. The Department of Parks (tel. 441/236-4201) offers free guided tours. Tours are offered primarily from November to May; call for schedules and additional information.

The island abounds with other places of natural wonder. Craggy formations shaped over the centuries out of limestone and coral dot the beaches along the southern coast, with towering cliffs forming a backdrop. The best place to view these formations is Natural Arches, one of the most photographed sights in Bermuda. Two limestone arches, which took nature centuries to carve, rise 11m (35 ft.) above the beach. Natural Arches is signposted almost at the end of South Shore Road, directing you to Castle Harbour Beach (which houses the arches).
