The not easy road conditions throughout Costa Rica are legendary, and they do so insecurely. Despite the constant promises to solve the problem, the hot sun, rain and rampant corruption exceed any progress made to improve their condition.
Many of these roads are being repaired and are also being extended, as is the case of Route 32 that connects the City of San José with the Costa Rican Caribbean. Precisely because of these jobs the trip takes longer than estimated. It is better to prepare for long driving hours.
Estimated driving times are easy to find on Google Maps, but keep in mind that it may take longer than estimated to reach your destination during the rainy season or if the roads have deteriorated.
Route numbers are very rarely used on road signs in Costa Rica, although there are frequent signs listing the number of kilometers to various towns or cities. Your best bets for on-road directions are billboards and advertisements for hotels.
