After two days of doing pretty much nothing except the necessary job of backing off photos, eating at Media Luna and gazing at a massive world map behind Liz, I was keen to do the one and only must do - the famous mud volcanos. Doing this would mean we could get out of touristy Cartagena where drinks and costs are comparable with the US.

My watch was 10 minutes out but we still arrived at the agreed time to be told the bus had departed. I did not take the news well - another day of doing nothing.

With the aid of some happy hours we had a go at cheering ourselves up but the cost didn't make us happy so we decided to go back to the room.

At about midnight things started to get really loud at the nightclub below. By 3 am both of us were thinking whether to join rather than put up with it.
