The Nicoya Peninsula's protected areas range from the forest at its southern tip to caves, turtle beaches and waterfalls farther north. Two are easy days from Santa Teresa; the rest fit a route up the peninsula. Trails are generally easy to follow, and you have a good chance of seeing monkeys, birds and more.

Cabo Blanco Absolute Nature Reserve
Cabo Blanco covers the southern tip of the Nicoya Peninsula, just south of Malpaís. Created in October 1963, it was Costa Rica's first protected area, and it inspired the national park system that followed. It exists thanks to Nicolás Wessberg, a Swede, and his Danish wife, Karen Mogensen, who settled nearby and campaigned to save the forest from logging and farming.
The reserve protects about 1,270 hectares of land and 1,790 hectares of sea. It's an "absolute" reserve: about 95% of it is off limits to visitors, which is why the wildlife is so easy to see on the part that's open. Much of the forest has grown back on old farmland.
How do you get there, and when is it open?
- Open Wednesday to Sunday, 8:00 a.m. to 4:00 p.m. Closed Mondays and Tuesdays.
- Entrance: the ranger station south of Cabuya is the only public entrance. There's no entry from the Malpaís side.
- From Santa Teresa: about 29 km, roughly an hour, via Cóbano, Montezuma and Cabuya. From Montezuma it's 20 to 25 minutes, and a small local bus runs to the entrance.
- Tickets: not sold online; pay at the ranger station.
Which trail should you take?
| Trail | Length | Time | Who it suits |
|---|---|---|---|
| Sendero Danés | A loop of about 1.5–2 km | Short and easy | Everyone, including young kids |
| Sendero Sueco | About 4.5–5 km each way, to Playa Cabo Blanco | About 2 hours each way | Fit couples; school-age kids who like to hike |
The Sueco trail climbs more than 200 m over roots and loose rock, and it's muddy in the rainy season. It ends at Playa Cabo Blanco, a white-sand cove with turquoise water, but the bottom drops off suddenly, so it's better for wading than swimming. Look for howler and white-faced monkeys, coatis, deer and anteaters, trogons in the trees and brown boobies over the water.
Insider tip: Be at the gate at 8 a.m. The animals are most active early, the forest is cooler, and you'll have time for the full Sueco trail and a long break on the beach before the 4 p.m. closing. Wear closed-toe shoes, and pack lunch and more water than you think you need. And check the day before you set off: the gate is closed on Mondays and Tuesdays.
Curú Wildlife Refuge
Curú is a private refuge on a family farm on the Gulf side, about an hour from Santa Teresa and 6 km from the Paquera ferry dock. The Schutt family has run it since 1933, and the property covers about 1,496 hectares of dry and moist forest, mangroves and beaches. It's the easiest wildlife day on the peninsula for families: easy trails, monkeys, deer, parrots and scarlet macaws, and a gentle bay for swimming and snorkeling. Some trails open only in the dry season. Day visits run from 7 a.m. to 4 p.m., and the entrance takes cards only, no cash. More in our guide to Tambor, Curú and the Gulf side and the Curú profile.
Barra Honda National Park
Barra Honda, about 22 km northeast of the town of Nicoya, is Costa Rica's cave park, created in 1974. Of more than 40 limestone caves, about 19 have been explored, and one, Terciopelo, is open to visitors, with a smaller cave, La Cuevita, for children. You go down with a guide from the local guides' association, clipped into a harness and wearing a helmet, then climb down a ladder of about 17 m among stalactites and stalagmites. Allow 3 to 4 hours in all.
- Hours: caves and trails 8:00 a.m. to 1:00 p.m.; last entry 1:00 p.m.
- Minimum age: 12 for Terciopelo, according to the park authority (SINAC).
- Booking: a guide is compulsory; reserve ahead by WhatsApp through SINAC's Barra Honda page. The park may close in heavy rain.
Barra Honda is 3 to 3½ hours from Santa Teresa on paved roads, so it isn't a day trip from here. It fits a drive north toward Sámara, Nosara or Liberia, or a day around Nicoya and the Blue Zone.
Ostional Wildlife Refuge
Ostional, just north of Nosara, is one of the world's most important nesting beaches for olive ridley turtles. Once or twice a month, thousands of females come ashore together over a few nights: an arribada. They happen all year, and are biggest in the rainy season, roughly August to November.
- A certified local guide is required during arribadas and the nesting season. The local guides' association can tell you when the next arribada is expected.
- Open daily 5:00 a.m. to 9:00 p.m. No flash, no white flashlights, no vehicles on the sand.
- From Santa Teresa: about 185 to 210 km, around 5 hours by paved road. The shorter coastal road crosses rivers that are often impassable in the rainy season, just when arribadas peak.
Stay in Nosara and go from there: see our Nosara guide and the Ostional profile.
Camaronal Wildlife Refuge
Camaronal, about 12 km south of Sámara, was created in 1994 to protect a beach where leatherback, olive ridley and hawksbill turtles nest. There's a ranger station. It isn't a swimming beach: a river meets the sea here, and crocodiles live in the estuary. Visit from Sámara or Carrillo; see Playa Camaronal.
Karen Mogensen Reserve
Named for Cabo Blanco's co-founder, this 960-hectare community reserve in the hills above Jicaral is run by ASEPALECO, a local conservation association. Its highlight is the 84 m Velo de Novia waterfall, about 40 minutes' hike each way with river crossings, and you can stay at the simple Cerro Escondido forest lodge, reached on foot or on horseback. Every visit must be booked ahead, with one of the reserve's guides, and the office is closed on weekends.
The entrance is at San Ramón de Río Blanco, up 16 km of dirt road from Jicaral, well north of Paquera. From Santa Teresa, treat it as a full day or, better, an overnight.
More nature near Santa Teresa
Closer to home, the Malpaís tide pools and the Montezuma waterfalls are easy half days, and a boat trip to Isla Tortuga takes you snorkeling in the Gulf of Nicoya. For a full list, see things to do in Santa Teresa, and for the whole peninsula, the Nicoya Peninsula map.
Frequently asked questions
When is Cabo Blanco open?
Wednesday to Sunday, 8:00 a.m. to 4:00 p.m. It's closed on Mondays and Tuesdays. There's no online ticketing: you pay at the ranger station south of Cabuya, the only public entrance.
Can you enter Cabo Blanco from Malpaís?
No. The reserve starts just south of Malpaís, but there's no public entrance on that side. You drive round via Cóbano and Montezuma to the ranger station past Cabuya, about an hour from Santa Teresa. A direct track from Malpaís to Cabuya exists, but it's a rough 4x4 route with river crossings, often impassable in the rainy season.
How long is the hike to Playa Cabo Blanco?
The Sendero Sueco is about 4.5 to 5 km each way, and most people take about 2 hours in each direction, so plan 4 to 5 hours with time on the beach. It's hilly, with roots and loose rock, and muddy in the rainy season. Start by late morning, since the gates close at 4 p.m.
Is Cabo Blanco good for kids?
Yes, with the right trail. Younger kids do well on the Sendero Danés, a loop of about 1.5 to 2 km near the entrance. School-age kids who like hiking can manage the Sendero Sueco to the beach: one family did it with a 5-year-old, in about 2½ hours each way. Bring lunch and plenty of water, and at the beach, wade rather than swim, because the bottom drops off suddenly.
What wildlife can you see at Cabo Blanco?
Howler and white-faced monkeys, coatis, white-tailed deer and anteaters are the usual sightings, with trogons in the forest and brown boobies over the sea. Arrive at 8 a.m., when the animals are most active.
Is Barra Honda worth the drive from Santa Teresa?
Only as part of a route north. The park is 3 to 3½ hours from Santa Teresa, and cave tours must start by 1 p.m., so it doesn't work as a day trip. It's a good stop between Santa Teresa and Nosara, Sámara or Liberia. The main cave descent is for ages 12 and up, with a shorter cave for younger children.
When can you see the turtle arribadas at Ostional?
Arribadas, when thousands of olive ridley turtles nest at once, happen once or twice a month all year, and are biggest in the rainy season, roughly August to November. A certified local guide is required. The local guides' association can tell you when the next one is expected. Ostional is about 5 hours from Santa Teresa by paved road, so stay in Nosara.
What wildlife refuge is closest to Santa Teresa besides Cabo Blanco?
Curú, on the Gulf side, about an hour from Santa Teresa. It's a private refuge with forest trails, monkeys and a calm swimming bay, and it's open to day visitors from 7 a.m. to 4 p.m. See Tambor, Curú and the Gulf side.
