A path of about ten minutes through the tropical forest separates the chaotic world of Costa Rican beaches from Playa Biesanz. You walk among tangled roots and dense canopies, with the muffled sound of howler monkeys echoing through the trees even before seeing the sea. Then, suddenly, the vegetation opens up to a crescent of dark, compact sand, nestled between two rocky promontories that protect the bay from winds and currents.
Playa Biesanz is located a few kilometers from the center of Quepos, in the province of Puntarenas, nestled along the central Pacific coast of Costa Rica. Its location within a protected natural cove makes it structurally different from nearby beaches: while Manuel Antonio National Park attracts hundreds of thousands of visitors each year, Biesanz remains off the mass tourism circuits, devoid of kiosks, rental loungers, and street vendors. This complete absence of tourist infrastructure is, paradoxically, its most distinctive feature.
The water and the colors of the bay
The water of Playa Biesanz changes color depending on the time of day and the light. In the early morning, it appears a deep emerald green, almost opaque, reflecting the vegetation that descends to the shore. Throughout the day, when the sun is high, the surface shifts to a transparent turquoise that allows for a clear view of the sandy bottom and submerged rock formations just a few meters from the shore. This transparency, combined with the almost absolute calm of the waters due to the closed cove shape, makes Biesanz one of the best spots for snorkeling along the entire coast of Quepos.
The sand is dark in color, tending towards gray-beige, with a fine and compact texture that distinguishes it from the lighter beaches of the national park. At the edges of the bay, where the forest meets the shore, volcanic rocks covered in green algae emerge, and during low tide, small natural pools where tiny crabs and fish can be observed trapped in the puddles. The perimeter of the beach measures just a few dozen meters: it is not a place designed for long walks, but for stopping.
The forest above the head
One of the elements that makes Biesanz visually unique is the fact that the vegetation does not stop at the shore. The trees grow right up to the water's edge, and the branches extend towards the sea, creating a sort of natural canopy at the beach's edge. The howler monkeys (Alouatta palliata), present throughout the biological corridor that connects Biesanz to Manuel Antonio Park, regularly move among the treetops during the morning hours and late afternoon. Their low and guttural call, which can sound like a roar, is often audible along the access path.
In addition to the monkeys, it is common to spot iguanas basking on the rocks at the beach's edge, and various species of tropical birds including toucans and parrots. The wildlife is not domesticated or accustomed to human food as is the case in some areas of the national park, which means that the animals maintain natural distances and behaviors unaltered by tourism. This makes sightings less guaranteed but more authentic.
How to reach Playa Biesanz
Access to the beach is exclusively on foot via an unmarked path that starts from the main road near the Hotel Byblos, a historic landmark in the Quepos area. The route is short but requires closed shoes or sandals with a non-slip sole, especially during the rainy season — which typically runs from May to November — when the ground becomes muddy and slippery. There are no official signs, and the path is more easily found by asking for directions from those staying in the area or consulting updated local maps.
The best time to visit is early in the morning, preferably before nine. During those hours, the beach is almost always deserted, the light is favorable for photography and snorkeling, and the monkeys are more active. In the afternoon, especially on weekends, local groups from Quepos may arrive. Swimming in rough sea conditions is not advisable: the bay is sheltered but not completely immune to the currents that form during seasonal swells. Bringing your own water is essential, as there are neither bars nor fountains nearby.
Why the Detour is Worth It
Playa Biesanz does not offer services, has no formal entrance, and does not appear in many printed travel guides. It is precisely for this reason that it works. In an area like Manuel Antonio, where mass tourism has transformed many beaches into extensions of resorts, finding a place where the only noise is that of the waves and monkeys represents something concrete and measurable, not just an advertising promise.
Those who arrive here with expectations of comfort will be disappointed. Those who seek direct contact with the Costa Rican coast in its least mediated form — clear water, dark sand, forest reaching to the shore — will find in Biesanz one of the most honest experiences that the Quepos region can offer.
