Went on a tour and visited Robinson Crusoe Island (that's not it's proper name but is what all the tours call it)
Went snorkelling here, but was pretty rubbish compared to the other places we had been shown at the resort. Nowhere near as many fish.
Had a BBQ lunch followed by a few shows (pics attached), and a walk through the jungle. Saw a huge turtle which was good.
Very touristy place though and if honest not as good as the waterfall tour, but still good.
