Short flights are a good alternative to long bus or car journeys. Flights within Costa Rica are usually very punctual and without long check-in times or nerve-racking controls.
Orientation in Costa Rica is quite easy. The most important road through Costa Rica is the Panamericana (Ruta 1), the road that runs from Tierra del Fuego to Alaska but is interrupted between Panama and Colombia. The Panamericana connects San José north with Liberia and then Nicaragua, south over the Cerro de la Muerte to Panama. Another road (32) leads from San José through the Braulio Carrillo National Park to el Limon in the east on the Caribbean of Costa Rica. To the west there is highway number 29, which connects San José and Santa Ana with Puerto Caldera and Puntarenas.
The park is located in the Caribbean, in the very northeast of Costa Rica and can only be reached by boat or plane. In the animal-rich Tortuguero National Park you will find an incredible amount of biological diversity and you can observe tons of animals up close. The opportunities for animal observation are almost unlimited. This is due to the many different landscape and climate conditions that can be found here. Tropical rainforests, beaches, alluvial plains, lagoons, rivers, caños - just to list some of the landforms.
They are not afraid, which is largely due to the fact that the animals in Costa Rica do not have to be afraid of people. There is no hunting here (or only very rarely), the Ticos themselves are very fond of animals. In some other Latin American countries you can see locals getting out of the car to photograph a sloth. Here is some information about the animals that you can see every day when traveling through Costa Rica. No claim to completeness.
