Running the Rio Verde and Rio Samana for 5 days outside of Medellín, Colombia this May. It isn't purely a whitewater trip, as I've organized some downhill mountain biking and rock climbing too. Still think it would be a great experience for anyone on the forum, from beginners to more experienced rafters. We'll be running class 2,3,4 rapids for 50+ miles of Colombian backcountry.
Have a group of 4 now, but looking for a few more! I made a website for the trip, so definitely check that out and of course ask me any questions you might have! I know it's coming up quick, but for those who can get off time, flights from the US to Medellin, are incredibly reasonable during those dates!
