Discovering the Underground World of Arrábida

This caving experience takes you into the heart of Arrábida Natural Park, a protected area known for its stunning limestone formations, lush greenery, and easy access from Lisbon. The caves themselves, like the Gruta do Médico and the Lapa Verde, are multiple overlapping galleries that reveal the geological history of the region. As water and mountain meet beneath the surface, you’ll find formations formed over thousands of years, creating an underground landscape that feels otherworldly.

The tour is led by experienced instructors who have over 30 years of expertise in exploring caves and conducting adventure sports. They are accredited by the Portuguese Speleology Federation, which adds an extra layer of trust in their ability to keep you safe while exploring these underground corridors. The guides, such as Rafael and Samuel, are praised for their friendly, welcoming approach, making even beginners feel comfortable and well-supported.

The entire process begins with a safety briefing and an introduction to your equipment, which includes a helmet, harness, headlamp, and abseiling gear. The guides emphasize safety, but also encourage a spirit of adventure—so expect to learn some rope techniques to help you navigate obstacles. If you’re new to climbing or abseiling, don’t worry: the instructors tailor the experience to your comfort level, and the focus remains on enjoyment and discovery.

What the Cave System Looks Like

Once inside, you’ll explore multiple galleries on different levels, which adds to the sense of adventure and exploration. Some sections, like the Lapa Verde, are where the mountain meets the sea, providing a fascinating intersection of geological features. The caves are extensive enough that you’ll feel like you’re wandering through a secret underground world, filled with stalactites, stalagmites, and other formations that have been sculpted over centuries.

The reviews highlight that the caves are indeed millennia-old, and the storytelling from the guides enriches the experience. As Josefien shares, “…they took us into the mountains with a breathtaking view,” showing how the natural beauty extends beyond just the underground. She also appreciated the guide Rafael’s attentiveness, which made the adventure safe and informative, even for someone climbing on rocks for the first time.

Expect to encounter tight passages, some requiring gentle climbing or sliding, but always with safety gear and guidance. The experience is suitable for those with a moderate level of fitness, but it’s accessible enough for most people as long as you’re comfortable wearing sportswear and sports shoes.

Your journey involves navigating several galleries, some on higher or lower levels, using climbing and abseiling techniques. The guides are patient and clear, often sharing fascinating stories about the caves’ history and the geology of the area.

Throughout the tour, you’ll be provided with water and energy bars, helping you stay energized during the physical parts of the exploration. The gear provided is modern and well-maintained, and the guides ensure everyone is properly equipped before starting.

The caves’ temperatures are cool, which is a relief on warm days, and the dim lighting creates an atmospheric experience—day and night truly merge underground, offering a sense of timelessness.
