Santa Teresa Without a Surfboard: Cabo Blanco Is Shut Mondays and Tuesdays

The reserve opens Wednesday to Sunday, the Cabuya sandbar needs a low tide, and the glow needs a dark sky. How to lay out your one non-surf day here.

Article Marta Daví · October 14, 2026 · 6 min read

If the one day you set aside for something other than surfing falls on a Monday or a Tuesday, Cabo Blanco is closed. SINAC's own entrance fee sheet lists the Reserva Natural Absoluta Cabo Blanco as open Wednesday to Sunday, 8 a.m. to 4 p.m., at $12 for non-resident visitors and 1,600 colones for residents (sinac.go.cr, read 13 October 2026). Every roundup of things to do here lists the reserve's trails. Almost none of them mention the two days you cannot walk them.

Which day you have free matters more in Santa Teresa than which activity you pick. Three things in this corner of the Nicoya Peninsula are decided for you: the reserve sets Wednesday to Sunday, the tide sets the walk out to Isla Cabuya, and the moon sets the night the water glows. Everything else bends around your morning.

Pin Cabo Blanco to a Wednesday, Thursday, Friday, Saturday or Sunday

Cabo Blanco has been protected since 1963 and sits at the bottom tip of the peninsula, past Cabuya, down a dirt road slow enough that you should budget an hour each way from Santa Teresa. There are two walks from the ranger station: a short loop in the forest near the entrance, and a long trail that drops to the beach at Cabo Blanco and climbs back. The long one eats most of a day, and the gate closes at 4 p.m., so this is a start-at-eight plan rather than an after-lunch one.

What SINAC publishes, and what we checked today, is the schedule and the fee: Wednesday to Sunday, 8 a.m. to 4 p.m., $12 for non-resident adults, $5 for non-resident children from 2 to under 12, 1,600 colones for resident adults. What SINAC does not publish is a way to buy this one ahead. Cabo Blanco is absent from the list of parks you reserve online at serviciosenlinea.sinac.go.cr, and absent from SINAC's list of gates that take a card on site (sinac.go.cr, read 13 October 2026). Carry colones in cash as well as a card, and treat the hour you arrive as the part you control.

Cabo Blanco Nature ReserveSanta Teresa, Costa RicaLocated on the southern tip of the Nicoya Peninsula in Costa Rica, Cabo Blanco Nature Reserve stands as a beacon of biodiversity and natural beauty. Established in 1963 as the country's first protected area, Cabo Blanco encompasses lush rainforests, pristine beaches, and diverse marine habitats, offering visitors a glimpse into the unspoiled wilderness of Costa Rica's Pacific coast. Key Points to Consider: Ecological Diversity: Cabo Blanco Nature Reserve boasts a rich tapestry of ecosystems,…

Howlers, capuchins and a long list of birds live in that forest, and the animals are loudest in the first two hours after the gate opens. Go early for the shade as much as the wildlife. The last stretch of road in is rough enough that most people take a quad or a 4x4.

If your free day is a Monday or a Tuesday

Do not drive to Cabuya. Put your water day there instead. The boat out to Isla Tortuga ignores the park calendar, the water around the island is clearer than the surf zone you have been swimming in, and boats go out in the morning, which is when this coast is flattest.

One thing to plan around: the Isla Tortuga tour leaves from Bahía de Tambor, not from the beach in front of you. That means a drive east across the peninsula before you get on the water, so set the alarm earlier than you would for a surf session and ask us about the pickup when you book.

Tortuga Island Santa TeresaSanta Teresa, Costa RicaLocated off the coast of Santa Teresa on the Nicoya Peninsula of Costa Rica, Tortuga Island is a pristine tropical paradise known for its crystalline waters, white sandy beaches, and abundant marine life. Accessible only by boat, this secluded island offers visitors a serene escape from the hustle and bustle of daily life, inviting them to immerse themselves in the beauty of nature and unwind in a picture-perfect setting.

A Monday or Tuesday is also the right slot for the canopy above Mal País, which holds up on an afternoon when the sky turns and with kids who are finished with sand.

The tide decides two of the best free hours you will have

The walk out to Isla Cabuya, where the village cemetery sits on a rock island under white wooden crosses, only exists at low tide. So do the rock pools at the north end of the beach, which hold starfish, crabs, urchins and water that goes bath-warm once the sun has been on it a while. Both are free. Both are shut to you at the wrong hour, and that hour slides roughly 50 minutes later every day.

Check the night before rather than the morning of. The Instituto Meteorológico Nacional publishes Pacific tide tables at imn.ac.cr/tabla-de-mareas. Aim to be at the pools or the sandbar within an hour either side of low water.

The moon decides the glow

People ask where in Costa Rica you can actually book a bioluminescence kayak or boat trip. This peninsula runs both, a kayak version and a boat version, and we book either for guests staying in Santa Teresa, Mal País or Montezuma. Darkness is the deciding factor. The plankton only read as bright blue when there is no moon in the sky, so the trip belongs on the darkest night of your week rather than the most convenient one. The dock and timing detail sit in our separate piece on Santa Teresa's moonless night.

Message us with your dates and we will tell you which night of your stay is the dark one, then hold that night before you fill it with dinner.

Montezuma, the other half of the same day

Montezuma sits over the hill to the east, and it pairs with a Cabo Blanco morning because the road back runs past Cabuya anyway. The waterfall trail starts behind town and involves wet rock and some scrambling. People get hurt jumping into the upper pools, and we would not do it with children along. Arrive in shoes you are willing to soak.

If you are driving yourself, our piece on getting to Montezuma and whether your car rides the ferry covers the crossing. If you are still working out the arrival, how to get to Santa Teresa works backwards from the last useful ferry.

How to lay out a three day stay

Take your dates and sort them in this order. Find a Wednesday through Sunday and give it to Cabo Blanco, early. Look up low tide and put Isla Cabuya or the rock pools in the hour that matches. Then put the boat or the canopy on the Monday or Tuesday the reserve is shut, and the glow on the darkest night, whichever one that is. Surfing fits in the mornings that are left, and if this is your first time standing up on a board, which beach and which hour matters more than which school you walk into.
