There are other places off interest to visit, the Machu Pichu area, flying over the Nasca lines, the telescopes in Chile, the area of the giant balls in Colombia, and travelling on the Amazon river, Patagonia, Tikal in Guatemala, and just seeing the ships transit the locks in Panama is interesting, or watch the monkeys in the jungle in Costa Rica.
It is to bad that the road has not been connected between Panama and Colombia, then it would be easy to traverse the whole of America from Alaska and Canada to Tierra del Fuego in Chile and Argentina.
