In terms of accessibility from the international airport, Atenas can be categorized as moderately convenient. While there are no direct public transportation options from the airport, travelers can opt for a private transfer service or rent a car to get to the town. The drive from San José is predominantly on well-maintained highways, with the last stretch involving a short drive on a paved local road. From other parts of the country, the road conditions are generally good, with some occasional potholes and rough terrain on rural routes.

When it comes to getting around Atenas, travelers have two primary options: renting a car or booking a private transfer service. Renting a car provides the freedom to explore the surrounding areas at one's own pace, but requires familiarity with Costa Rican driving habits and road signs. On the other hand, private transfer services offer a convenient and hassle-free experience, with professional drivers who know the roads well. However, this option may be more expensive and limit one's flexibility. From a safety perspective, both options are generally considered safe, but travelers should exercise caution when driving at night and be mindful of potential scams when booking private transfers.

It is highly recommended that travelers book their transportation services in advance, especially during peak travel seasons. This ensures availability and the best rates, as demand for these services can be high. Moreover, advance booking allows travelers to plan their itinerary more effectively, avoiding any potential delays or last-minute hassles.
