Just to let you know that the last pictures of Mexico are now online... you can view them on the Mexico page to have an idea of what Palenque Ruins are like.
Instead of going to Guatemala directly as we initially planned we crossed through Belize... and it was really worth it ! We only had two days on our vehicule permit but still managed to take a small boat to Caye Caulker. Snorkling there was amazing. A lot of fishes and sea rays... a lot of coral (it is the second reaf in the world).
You can see a few picture of Belize here.
