The Venado Caves (Cavernas de Venado) are a wild limestone cave system about 45 minutes from La Fortuna, near the village of Venado in northern Costa Rica. Visits are by guided tour only, and the tour takes about two hours underground. You’ll wade through an underground river, climb over rocks and squeeze through at least one very tight passage. It’s a good half-day adventure for fit travelers and older kids, but skip it if you’re claustrophobic or have back or mobility problems.
This guide is for travelers staying around La Fortuna and Arenal who are deciding if the Venado Caves belong on their itinerary. It covers what the tour is like, how hard it is, how to get there, what to wear and when to go.

The caves
What Are the Venado Caves?
The caves formed in limestone laid down when this part of Costa Rica was under the sea, millions of years ago, and marine fossils are still visible in the walls. The mapped system runs for roughly 2.7 kilometers (about 1.7 miles), with chambers up to about 35 meters high. Inside you’ll see stalactites, stalagmites and other formations, plus an underground river and small waterfalls. Local hunters stumbled on the caves in the first half of the 20th century, and cavers have been mapping them since.
Venado isn’t a developed show cave with walkways and lighting. You see it by headlamp, on the cave’s own floor, which is the main reason people go.
The tour
What the Venado Caves Tour Is Like
Tours start with a short briefing and gear: a helmet, a headlamp and often rubber boots. From there, a local guide leads small groups through the cave. Expect:
- Water: parts of the route follow the underground river, and you’ll wade through it.
- Climbing: scrambling over wet, slippery rock and up short drops.
- Tight squeezes: the best-known is a narrow crawl that guides call the “birth canal.”
- Wildlife: bats roost in the chambers, and you may see crickets, frogs and whip spiders (sometimes called scorpion spiders), which look alarming but are harmless to people.
Guides point out formations and fossils along the way. Not every guide speaks fluent English, so ask for an English-speaking guide when you book if that matters to you. Afterward, operators usually have a changing area and showers.
Fit check
Who the Venado Caves Are Best For
- Good fit: active travelers, teens and older kids who like getting dirty, and anyone who has done the main La Fortuna sights and wants something different.
- Think twice: anyone uneasy in the dark or in enclosed spaces, travelers with knee or back problems, and young children; check the operator’s minimum age before booking.
- Skip it: claustrophobia, pregnancy, heart conditions, or serious mobility limits. The cave isn’t accessible.
Getting there
How to Get to the Venado Caves From La Fortuna
The caves are about 45 minutes north of La Fortuna by car. The usual route heads toward El Tanque and Monterrey, then turns off toward Venado, with the last few kilometers on gravel. Search “Cavernas de Venado” in Waze or Google Maps. The gravel stretch is short; drive it slowly, and expect mud after heavy rain. See our guides to driving in Costa Rica and rental car insurance.
Without a car, book a tour with transport from La Fortuna. Those tours take about half a day and usually include the guide, gear and hotel pickup.
Tour with transport vs. going on your own
- Tour from La Fortuna: easiest, with no driving on gravel; costs noticeably more than paying the entry and guide fee at the cave.
- Drive yourself: cheapest, and you can combine it with other stops; reserve your time slot with the cave operator ahead, especially in the dry season and on weekends.
Prices and tour times change, so confirm them when you book.
Pack
What to Wear and Bring
- Clothes you can ruin: quick-dry shorts or pants and a synthetic T-shirt. Cave mud can stain.
- Shoes: rubber boots if offered, or closed water shoes with good grip. Avoid flip-flops.
- A full change of clothes, a towel and a plastic bag for the wet gear.
- Leave valuables behind. If photos are allowed on your tour, use a waterproof case with a strap; some tours don’t allow cameras at all.
- Insect repellent for the walk to the entrance.

Timing
Best Time to Visit
The caves are open year-round, and conditions underground change less than conditions outside. The dry season, roughly December to April, gives easier roads and a lower river. In the rainy season, especially after heavy downpours, the river runs higher and tours may be shortened or canceled; book a morning slot and keep a backup plan. See our guide to the rainy season.
