La Tovara National Park, San Blas, Mexico

The town of San Blas is a starting point for exploring Mexico's La Tovara National Park.

The park is a huge swath of protected mangroves and marshlands that is a bird-watching paradise.

Every winter the area is taken over by birds from both North and South America who have descending upon it for its abundant food supply (read lots and lots of mosquitoes).

The park is also home to a considerable number of crocodiles.

We took a boat ride through the mangrove swamps, spying all sorts of birds along the way.

We also spotted some newly hatched crocodile babies and a couple of full grown ones lurking in the depths.

The ride ended at a crocodile park where the beasts are protected and bred.

Unlike the ones we'd spied during our boat ride there, these big lizards are kept in cages so their eggs can be scooped up and hatched, then sent out to other parts of Mexico that are experiencing a shortage in their wild crocodile populations.
