Walk across magnetic sand on the edge of the rainforest

Just a few minutes from Puerto Viejo a wide, dark beach runs directly along the road: Playa Negra. What at first glance looks like a normal stretch of coast turns out, on closer inspection, to be a fascinating natural phenomenon.

It contains magnetite, an iron-rich mineral that actually reacts to metal. You don’t need a magnet: simply hold your key or a coin lightly over the sand and watch as fine grains cling to it. A simple experiment that surprises – especially because you can experience it in the middle of a walk.

Playa Negra is ideal for a short stop and for walking barefoot in the warm sand. The beach lies right next to the road, is easy to reach and offers space for small discoveries.
