Hey, cool! I didnt know you could dive in the lake. What do you see there? Yes, San Marcos was nice, but a bit too hippy haha :D I saw the place from Iguana Perdida but didn't have time to go there in the morning. I did teach a class spontaneously at our hostel. They had a big platform right next to the lake, which was perfect to practice. And once I started my morning practise, people joined. It was a nice vibe, and great to teach a international group of backpackers ;)
