We are loving Columbia.    The people are friendly, the town is bustling and full of colour and the countryside is fascinating.    We’ve cycled miles, eaten local food (with no detrimental effects), had a real challenge to understand the language and currency (5,000 pesos = £1), socialised and been on a guided tour to Quebrada Valencia (famous for its waterfall and crystal clear water) and Taironaca (architectural ruins of the Tayronas, rainforest and tubing).      The tubing was such fun: more a drift than shooting the rapids but it gave us a wonderful opportunity to see the rainforest and wildlife from the water.   We were thrilled to see howler monkeys – shame they sit so high in the trees.    We could easily spend a month in Santa Marta without any danger of getting bored but the days are just flying past and we can hardly believe we will be on the move again tomorrow!
