Crossing the border from Nicaragua to Costa Rica was pretty easy. On the Nicaragua side they did require some paperwork and photocopies. It took probably 30 minutes to get through.
Costa Rica has clearly marked highway signage with towns and distances clearly presented. They also have clearly posted speed limits that are enforced by radar wielding police officers. I regulated my riding according. I didn't mind because the roads were in good condition, the traffic seemed to obey the rules of the road and I was riding through beautiful Costa Rican countryside.
I arrived in Sumara after sunset. I rode around in the dark looking for a hotel. I eventually came across a place called Las Mariposas Hostel.
The managers offered to let me park my bike in their bodega (shed).
