A quick summary of our Costa Rican destinations on this leg of the trip included:
Alleluja (which is the San Jose airport just outside of San Jose) to San Jose by hostel's airport shuttle. At the hostel, we had a Mapache Rental Car delivered to us. We travelled in "Jimny Cricket" from San Jose through San Ramon to La Fortuna / Arenal Volcano. Around Lago Arenal back to the main highway to Liberia. From Liberia, we headed south to Tamarindo with a day trip to Playa Avellana. Then back through Liberia where we dropped off "Jimny", took a shuttle to the Liberia bus station, and a bus onward to Penas Blancas (the CR-Nica border crossing). We then went over the border for a few days to Nicaragua.
Here is the route we followed:
