While Bonaire is mainly known for its diving there is plenty to do above water too. We managed to fit in several days of exploring the island during breaks from diving and also while I had a minor ear infection and so had to stay out of the water for 5 days.
The far north of the island is the Washington Slagbaai National Park which I have already written about. Just South of that is a large lake called Gotomeer which is one of the flamingo nesting sites. Just inland from the East coast there are escarpments containing caves with Indian inscriptions. There are also the wind turbines for the island. The South of the island is mostly salt pans and is very flat and wet. Also on the East coast is Lac, a natural harbour bordered by mangroves and used mainly for windsurfing. Close to the airport and the capital, Kralendijk is the Donkey Sanctuary, where sick, orphaned and injured wild donkeys are taken in and cared for.
We made several trips into the National Park, for diving and non-diving. The highest peak on the island is Seru Branderis at 241m. It takes about two hours to get to the top and back from the car park. The first part is an easy walk through woods and scrubland and the higher part is a scramble up the volcanic rock of the island. The view from the top is spectacular. You can see the whole of Bonaire and on the day we went up we could see across to Curacao as well.
Unfortunately, since I arrived at Coral Cay in Tobago I haven't had time to finish this properly. But thought I would post it anyway. See facebook for some photos.
