On the Yucatan shore, also close to Playa del Carmen/Cozumel, you can do some amazing sweet water diving (brakkish) in the sinkholes (Cenotes). Don't miss out on that while you're in the area!
Cons: Not a lot of life in there...almost no fish at all
Amazing steep walls, clear water, best biodiversity I've ever seen. Beats Mexico, Egypt, Maldives, Caribean anytime in almost all aspects...by far...
Cons: Quite difficult to reach (this is improving though), and not much else to do beside diving.
Literally everyone I took to this place liked it (especially all art museum haters). IMHO THE main charm is the fact you can see his style changing from painting to painting. He's slowly going mad!
Cons: Can be really crowded with long waiting lines outside.
A pageturner that will grab you instantly. Called 'Millenium 2' in some countries. Stieg Larsson was a genius!
Cons: Not as good as the 3rd Millenium book...once you've finished #2, there is no way you can avoid reading the 3rd. Make sure #3 is within reach when you finish the last page!
