Condos and houses in resort areas such as Tamarindo are built and priced to sell to people from the USA and Canada, and are too expensive for most local workers. This is common in many resort areas, including those in the USA, but the problem is amplified in areas of the developing world when the resort housing market caters for foreigners.
I think it is wonderful that there is good bus service for workers, even in a rural area such as the part of Costa Rica where Tamarindo. It enables people in a wider area to share int he benefits for the local economy from the tourist industry. This bus is on the road at the entrance to the Langosta section of Tamarindo.
We have photos of the Atacama Desert of northern Chile on our Viva la Voyage travel photo site this week. It is an amazing, colorful, barren landscape.
