Yungas


 While we waited for a voltage regulator for Karen's bike to be shipped from the states we decided to visit Coroico in the Yungas. The Yungas is verdant  area on the eastern slopes of the cordillera. It is characterized by frequent clouds and fog, warm temperatures, and almost daily rain. Leaving La Paz one travels through a number of micro-climates. The pass, coming from La Paz is more than 15,000 feet and the western slope features towering peaks of stark and barren andesite.

On the western side of the pass ice is not uncommon in the shady areas, while within a mile or two on the other side it begins to be replaced by moss.
Aout 10 miles past the cumbre (the highest point), we get our first glimpse of the road down to the Yungas, and the dramatic change of climate and landscape. The US State Department has labeled this road "The Death Road." In fact there is a cooperative effort between Bolivia and US AID to complete a new two-lane road  to Coroico a bit further northwest to replace this one-lane road.  It is fairly obvious that the motive in building this new road is for control of illicit cocaine trade. The Yungas is the heart of coca cultivation (the leaves are legal and widely used in Bolivia and elsewhere). This road has a few short stretches where it is two-lanes wide, but the majority of it is an extremely narrow one-lane that has traffic in both directions. The rule here is a left hand traffic pattern with right of way going to the uphill traffic. There are small spots every few hundred meters or so that are wide enough to pull to the side so the uphill traffic can pass. The majority of the traffic consists of trucks and buses.
