Playa Hermosa is a tiny beachside village in the Guancaste province less than half an hour west from the airport at Liberia. Playa Hermosa appears to have no reason to exist other than its beach. Just off the main road on the way to Playa Panama, it has no post office, no banks, and no ATMs. (You'll need to get to nearby Playa del Coco for those.) There are two small general stores for the necessities. What it has is a long, wide, clean beach with warm, clear water; stunning sunsets; and no crowds.
The village is bisected by a small stream that has no bridge, so if you are driving, pay attention to whether you want the first or the second entrance to get to your particular destination. A very brief wade through very shallow water gets you from one side of the village to the other via the beach.
We were there at the end of November, and the weather was almost always hot and sunny. We had one brief afternoon rainstorm that lasted about 1 hour. The climate is dry, so the heat never felt oppressive, and the evenings were very pleasantly warm. The sand can get very hot in the afternoon, so bring those flip-flops to get to the water.
Playa Hermosa is a getaway spot for both Ticos and tourists, with many local families coming in to enjoy the beach on the weekends. All the tourist-oriented businesses we visited were owned by either Canadians or Americans.
Tourist development is starting to catch up with this sleepy, idyllically neglected spot. Many gated condo properties are being built in the hills along the main road; the all-inclusive Villa Sol resort development sprawls in the hills off the beach in the east end; the luxury Four Seasons resort can been seen across the bay; and an expensive private condo is slated for the last empty property on the beach. If you want what is still a somewhat out-of-the-way spot, the time to visit Playa Hermosa is now. In 5 years, the village will probably be almost totally transformed into a smaller version of the neighbouring boisterous Playa del Coco.
