From Jeri we headed west to the Lencois Maranhenses national park – 15,000 sq km of rolling sand dunes. We walked across mile upon mile of blinding white sand dunes interspersed with turquoise freshwater lakes.
It was unlike anything I had ever seen before and we even got to swim in the lakes before watching sunset from a dune.
The next day we caught a ferry past villages built on sand dunes and along jungle-lined rivers to the remote village of Cabure built on a sandbar between the river and the ocean.
It was beautiful and desolate; our only concern was whether we wanted to swim in the ocean or river.
