An In-Depth Look at the Underground Tour

What’s Included and What’s Not

Starting with the basics, this tour is priced at $290.27 per person, which might seem steep at first glance. But considering it’s a full-day private experience that includes hotel pickup and drop-off, transport in an air-conditioned minivan, and all caving gear, it offers good value if you’re after a personalized and hassle-free adventure. The fact that a professional guide also captures photos adds a memorable touch—something many travelers find invaluable.

However, it’s worth noting that tickets to Algar do Carvão and Gruta do Natal are not included. Both are iconic sites, but they are currently closed for renovation until 2026. This means you’ll visit some caves that aren’t open to the public, which could be a minor disappointment for those eager to see every major site.

The Itinerary: What to Expect

The tour kicks off at 9:00 am. Since it’s a private experience, your guide will tailor the day to your pace and interests—whether that’s focusing on the caves, hiking trails, or a mixture of both. The main highlight is exploring Christmas Cave and Algar do Carvão, famous lava tubes that showcase ancient volcanic activity.

The caves are described as spectacular and easy to visit, though they require some physical effort—so good hiking boots are recommended. The tour also includes additional caves that are not open to the public, which makes it feel exclusive and more adventurous. You’ll be equipped with a helmet and other gear, and your guide will ensure safety throughout.
