Considered one of the best surfing locations in the world, the beach is extremely dangerous. People die here every year, as they do in Jaco as well, and the riptides and large waves in Hermosa are notorious. Be extremely careful when swimming in Hermosa. The black sand at midday is scalding hot, and will burn your feet. But the beach is beautiful and uncrowded. Most people prefer to spend their time in Jacó, and Hermosa is largely ignored. A great place for a drink or a snack while in Hermosa is the Backyard Bar. In contrast to the rowdy bars of Jaco, this one has a very mellow, surfer vibe.
The river is famous for one thing, its crocodiles. Park alongside the road and walk along the bridge to view the hundreds of crocodiles lying below. Many of the local resorts and hotels offer crocodile tours to Tarcoles where you can see the creatures up close. If that's a frightening idea, the view from the bridge is impressive enough.
