What is the best transport in Costa Rica, and how to get around?

Whether or not travel by airplane in Costa Rica?

Flying from Amsterdam to Costa Rica without a stopover is possible. Flight duration is about 14 hours.
Flying is by far the most comfortable way to get from one place to another in Costa Rica. There are quite a few flights between the fifteen different airports. Of course, this is less sustainable and more expensive than taking the bus.

Road quality in Costa Rica is fairly poor. Except for a few highways between major cities, it is helpful to drive carefully if you rent your own car. With an international driver's license you can certainly rent a car, and sometimes even a Dutch license is good enough. Be sure to get a spare tire with a car (you will probably need it). It is also important to carefully check the car for scratches and damage, so that it is clear later, whether the damage was caused by you or was already there. In this regard, it is finer to take public transportation.

There are only two train routes in Costa Rica that are still used. From Heredia to San José (half an hour) and from Pavas to Curridat (via San José and San Pedro).

Bus transportation in Costa Rica is well organized and inexpensive. Comfortable buses run longer distances. American school buses provide city transportation and shorter routes. For shorter distances, prepare yourself mentally as you will be shaken up considerably.

In the capital San José, use the red cabs as much as possible. These are required to use a taximeter. Do ask in advance if this meter works. If not, agree on a price in advance.
