Lake Gotomeer is a 35 acre saline lagoon. It once was a bay of the Caribbean before being chocked off and isolated by coral. It is on the Ramsar List of international wetlands. Goto Lagoon is located within Washington Slagbaai National Park. This covers 13,500 acres or about 20% of Bonaire. The nature reserve is home to numerous bird species. The most famous is the flamingo. But bird watchers might also spot the Caribbean parakeet and the endangered yellow-shouldered parrot. Both are unique to this island.
