For scuba divers, a dip in the clear, chilly waters of Lake Nahuel Huapi reveals a wealth of fascinating underwater sights and experiences. Though it's true the lake doesn't contain many colorful fish or exotic marine life, there is still plenty to discover beneath the surface. Explore the submerged park off the shores of Gallinas Island, complete with a sunken chairlift and a 3 meter (10 ft) statue of Neptune, the Roman god of the sea.
Prefer less staged exhibits? Then head to Victoria Island, where divers are treated to both an exterior and interior view of a sunken passenger vessel. As you've probably guessed, water temperatures are mighty cold (10 – 13 C [40 – 45 F]), but with visibility up to 22 meters (70 ft) it's a hard dry-suit adventure to pass up.
