I am in medellin right now. Whenever I am in a new city normally I find a tour group / bar hopping group or a pub crawl and join in. As I dont speak spanish at all it is very difficult for me to go into a general club alone.
I had been in medellin for a few days now and have not found any groups like this. Is there anything happening during the New Years night with an international flavor? May be an exotic mix of american / european tourists hanging out at a local bar or a club. If so I would love to join on.
