What Are the Venado Caves?
The Venado Caves are a cave system cut into old sea-floor limestone, formed over millions of years. Guides point out shells and coral in the rock, from the time when this land was under the sea.
Researchers from the University of Costa Rica have mapped nearly 5 km of passages across three caves, and dye tests showed that the water links all three. It’s the largest known cave system in Costa Rica. The tour goes into one of them, called Gabinarraca, which has been open to the public for more than 20 years.
A local hunter, Lael Herrera, found the first two chambers in 1945. The caves take their name from Venado, the farming village nearby. Inside, you pass stalactites, stalagmites and a big chamber with water falling from the ceiling.
Where Are the Venado Caves?
The caves are in Venado, a small farming district of San Carlos, in Alajuela province. Some guides place them in Guatuso, but they’re in San Carlos. They’re on private land, and a local company called Cavernas del Venado operates the tours.
The drive from La Fortuna takes around 45 minutes to an hour. Most of the road is paved, but the last stretch to the caves is a slow gravel road. A regular car usually manages, but the gravel gets muddy after heavy rain, so take it slowly. Renting a car in Costa Rica covers the insurance you’ll want on that drive.
There’s no direct bus from La Fortuna. A taxi there and back costs more than a tour for one or two people, so ask for a round-trip price first. Without a car, a tour with pickup is the easiest way to go.
Two Ways to Visit the Venado Caves
There are two ways to see the caves. You can drive yourself and book the caves’ own tour, or you can book a tour from La Fortuna with pickup. The time inside the cave is much the same either way.
The Caves’ Own Tour (Drive Yourself)
The caves’ own tour costs around $40 per person, and kids can join from age 5. Tours leave at 8 AM, 10 AM, 12 PM and 2 PM, and each one takes around 2 hours at the caves. On some days, one of the slots isn’t offered, so check the booking page for your date.
Our pick is the same 2-hour tour, with a bilingual guide. Boots, a helmet, a flashlight and a mask are included. You also get private parking, showers, restrooms and use of the swimming pool after the tour, when it’s open. Towels, socks and a waterproof phone case aren’t included, so bring your own.
Online bookings need at least 2 people, and you can cancel for a full refund up to 24 hours ahead. With a rental car, two people save around $100 compared with a tour from town.
Tour From La Fortuna With Pickup
A tour from La Fortuna includes pickup, entry, gear and a guide. The whole trip takes 4 to 4.5 hours. Pickups are around 7 to 7:30 AM for the morning tour and around 12:30 to 1 PM for the afternoon one.
Our pick costs around $92 per adult and takes 4.5 hours, with up to 20 people. Transport in an air-conditioned van is included, plus the entrance fee, a certified nature guide and water. You also get a flashlight, a mask and a helmet. Food and tips aren’t included. Kids under 7 can’t join this one, and it needs at least 2 paying adults to go ahead.
Some companies add $10 to $25 per person for pickups at lodges outside town, so ask about this when you book. Bring a change of clothes, a sun hat and a camera you don’t mind getting wet.
What to Expect Inside the Venado Caves
The tour starts with a short briefing at the entrance, where you put on the boots and helmet. Then you follow the guide into the cave, along the underground river.
You walk, crouch and crawl through the passages. In some parts, the water can reach your knees or higher. You may scramble up wet rock, and one route ends with a climb up a small waterfall. Swimming in the river isn’t allowed, but you’ll be wet most of the time.
The guide shows you the main formations, like the one known as La Papaya. Bats hang above some sections, and that’s why masks are part of the gear. Expect a few scrapes and a lot of mud.
Stay on the guide’s route, and don’t touch the formations or the animals. Many guides also stop at one point and ask everyone to switch off their lights for a minute.
What to Bring to the Venado Caves
The caves give you rubber boots, so you don’t need special shoes. Here’s what to bring:
- Clothes that can get wet and muddy, like quick-dry shorts or light pants
- A full change of clothes and dry shoes for afterward
- A towel and socks
- A plastic bag for your wet, muddy things
- Water and bug spray for the walk to the entrance
- A waterproof case, in case you want to take your phone in
Long pants protect your knees on the crawls. Don’t leave valuables where people can see them in the car.
Best Time to Visit the Venado Caves
The caves are open every day of the year, though holiday hours can change. You’ll be wet the whole time anyway, so a cloudy or rainy day works well. It’s a good plan for a morning when the volcano is hidden.
Morning tours are the best pick in the green season, roughly May to November, because afternoon storms are more common then. In the dry season and over the holidays, book a day or two ahead.
What to Do After the Venado Caves
After the caves, you can go to one of the hot springs in La Fortuna, because it’s the best way to warm up and wash off the mud.
You can also stay for lunch at the restaurant at the caves, which serves Costa Rican food. With four days in the area, the caves make a good half-day trip. The La Fortuna itinerary shows where they fit.
Is the Venado Caves Tour Worth It?
Yes, go for the Venado Caves tour, because it’s nothing like the other tours around La Fortuna. Most tours here are about the volcano, the forest or the hot springs, and this one takes you underground, through mud and water.
With a car, book the caves’ own tour directly and drive there, as it’s the cheapest way to go. Without one, book a tour from La Fortuna with pickup. The caves fit a half day, and other short trips are listed with the things to do in La Fortuna.
Venado Caves FAQ
Is the Venado Caves Tour Hard?
It’s not hard, but it’s physical. The caves ask for a basic level of fitness, as you’ll walk, crouch, crawl and climb over wet rock for around 2 hours.
It’s not a good fit for people with reduced mobility or trouble on uneven ground. The caves also advise against it for anyone with heart or back problems. Expect a few scrapes and sore knees by the end.
Is the Venado Caves Tour Claustrophobic?
There’s one narrow section, nicknamed the birth canal, and it’s optional. Anyone who feels claustrophobic can skip it, and the guide takes you around it.
The rest of the cave has low ceilings in places, so you’ll crouch and crawl at times. Tall or broad-shouldered people may want to skip the squeeze. People with severe claustrophobia should skip the tour.
What Animals Live in the Venado Caves?
Bats are the ones everyone remembers, hanging from the ceiling in some sections. Look closer and you’ll also find cave spiders, crickets, small fish and freshwater crabs.
None of them are a danger to you, but the guide will ask you not to touch them. The masks in your gear kit are there because of the bats.
What Is the Minimum Age for the Venado Caves?
At the caves, kids can join from age 5, and children must be with an adult. Tours from La Fortuna set their own limits. Some take kids from 5, and others from 7 or 8.
The tour suits active kids who don’t mind getting dirty. It needs a basic level of fitness, so check with the company before booking for younger kids.
Do Venado Caves Tours Go Ahead in the Rain?
Yes, tours go ahead in light rain. Heavy rain can raise the underground river, though.
When that happens, the caves may cancel the tour and offer you a new date. On our pick for the caves’ own tour, you get a full refund when the tour is canceled for weather.
Can You Visit the Venado Caves and Río Celeste in One Day?
It’s not a good idea. Río Celeste is 1.5 to 2 hours from La Fortuna in another direction, and the trip there takes a full day on its own.
Plan the caves as a half day, and keep Río Celeste for another day. Tickets and the trail are covered in the Río Celeste from La Fortuna guide.
