Highway to the Andes
“You‟re going to DRIVE to Merida? But it‟s so far – it will be horrible”. This is what my friends said when I told them I wanted to go to Merida by car.
The Venezuelans love to take planes. Domestic flights are reliable and cheapand there are lots of them. So people thought it a little strange that I wanted to hire a car and drive, what is only 700 kilometres, to the Andean city of Merida.
But the journey wasn‟t horrible at all. The roads were in good condition, there was motorway for part of the way and regular petrol stations (where petrol cost lessthan water).
There was even a roadside self-service restaurant between Caracas and Valencia.
I drove out of Caracas, and its mixture of modern skyscrapers and old, poor housing, on a mountainous highway. At first the scenery was Caribbean: bananas, small villages, coconut trees.
When you reach Valencia, orange trees mix with sugar-cane. A little further on, past Acarigua, the country changes into the llanos or plains. This is real cowboy country, with huge isolated farms and occasional roadside ovens where you can buy roast beef by the kilo. Everyone agrees that the last four hours to Merida are the best, so it‟s a good idea to spend the night in Barinas and drive the remaining 250 kilometres in the morning. An hour or so out of Barinas and the Andes seem to appear suddenly around the corner. From then on, it‟s an exciting climb up to 3,000 metres and the Venezuelan paramo.
The paramo is the cold, windy mountain range. Although there are no trees in these mountains, there are lots of plants and flowers. At 3,600 metres you notice that the air is getting thinner. After a strong cup of Venezuelan coffee at the village of Apartaderos, my heart seemed to beat much faster than usual.
My car didn‟t like the thin air and slowed down. I didn‟mind – this gave me time to look at the mountains. Locally,”crossing the paramo” means dying, and the car seemed to know this.
The scenery on the way down into Merida is spectacular. Some of it is Andean with its low, stone villages and potato fields and some is Alpine with its rivers full of fish, and inviting hotels. Merida itself is a pleasant town. It has three claims to fame: the University of the Andes, the world‟s highest cable-car – to the snowy 4,800-metre Pico Bolivar – and an ice cream shop with the world‟s biggest number of flavours (400), including garlic and spaghetti bolognese. But this wasn‟t why I had come.
