I know it seems touristy and cheesy, but just do it. Do it, and do it early in your trip because you’re likely to make friends that will last longer than your time in Cartagena. For a set fee (I think it was about $20 per person, but not certain) you will ride around for a few hours with 50 or so of your best new friends from around the globe, drink the rough local aguardiente freely, and sing new songs at the top of your lungs. In fact, be smart and buy your own clave, guiro, or maracas from one of the hawkers plying the streets of el Centro before you board so that you can play along with the Vallenato band in the back. Buy your own bottle of Ron Medellin to take with you – you’ll make plenty of new friends by sharing shots with former strangers that can’t quite stomach the cheap local firewater the chiva provides. The chivas will tour around to pick up folks from various hotels that booked their activities in advance – welcome each group loudly with a smile and you will be their hero. Each bus has its own MC who will goad you into activities and contests, the most fun of which are against the other chivas at stoplights. Don’t be a wet blanket – throw yourself so far into it that other passengers think you’re part of the show and you will not be disappointed. Most chivas stop into several discotecas for a drink and a dance, then load up and you’re off! If you do nothing else touristy the whole time you are there, do this.
