Cabo Polonio Lighthouse

Mon, 01 Jan 0001 00:00:00 +0000

Years ago, went on a trip to explore Buenos Aires and Uruguay. The best place we visited was Cabo Polonio, a very small city, reachable only by 4x4 or walking. Amazing place to meet. Hope to visit it again with more time. The photo is of its lighthouse.

Near it, you can find some sea lions laying around.

Ilhabela is an archipelago and city in Sao Paulo, Brazil. Reached by ferry or boat, it has a vast number of available treks and beachs to explore. Went with my dad and some friends some years ago.

Ubatuba was some of the best beaches in Sao Paulo state. Really clean water and high biodiversity. With some luck, you can even find turtles and dolphins there!
