Bordered by the Atlantic Ocean and stretching 40 miles into the jungled interior, we kayaked and portaged more than 200 miles around the park's perimeter, seeing this wild country from a new and different perspective. Along the way we encountered river-swimming elephants, manatees, tarpon, surfing hippos, gorillas and more. By trip's end it was hard to decide which were the most beautiful, and the most difficult, parts of the expedition, but it was eye opening, for us all.
