A friend of ours - Georg - offers great ultra light flights! Its a very unique way of seeing the country. "Jorge" - a native German - is a truely unique character. Visit his airport on the right side of the Costanera going south, right after the last big supermarket and the second entrance to Bahia Ballena. His website is www.ultralighttours.com.
I first came to Costa Rica in 1998. I fell in love with the country right away for so many reasons. I have been coming, living and unfortunately never staying off and on since.
