I love caves. This one is easy to get down and up. The story of how the cave was formed was the best part of the trip. I will leave it up to the guides to explain the story.

This is so interesting and beautiful. None of our pictures captured how pretty it is inside. I'm a bit leery of caves in general (a bit claustrophobic), but this was fine. It's cool inside so bring a light jacket. Be prepared to get dipped on a bit and to me amazed.

This was a unique experience to walk into a volcanic cone. Fabulous it was too. Wet and drippy and cool, with lots of steps. Luckily there are hand rails all along the steps. Wear flat sensible shoes to see the caverns, silica stalagmites (quite small but amazing) and other volcanic formations. Prepare to stand in awe and gaze!

Great time exploring this volcano. Lots of stairs so wear comfortable shoes (actually saw a lady is heels, impressive but not practical) and layers, you will work up a sweat climbing up the stairs. It is moist in there.

This is a must do while on the island. It's quite the work-out but worth every bit. The lake at the bottom is amazing. The view from inside is beautiful.

This cave was pretty cool. There wasn't a tour or anything, but was cool to walk down into, had stairs and lights throughout and even a small lake at the bottom. Very wet inside, I would recommend sneakers.. not flip flops..

I've been to this attraction 3 times and it always amazes me!!! The last time we went or kids were to small to remember, I'm glad we had a chance to come back at an age our children will now remember because it is incredible. A must see attraction. Where else in the world can you walk into a volcano?

I am a portuguese travel blogger, I read a lot about several different places and I had no idea that Terceira island had such an amazing attraction as this one. I have had the chance to swim inside a beautiful crater in São Miguel island, to walk around a huge crater in Faial island, to relax inside natural hot water... More

This is a superb, amazing place. As the guide said, this is the only place in the world where you can actually visit the inside of a volcano. The volcanic caverns are huge with a lake at the bottom caused by all the drips of water. It was also quite quiet. An amazing attraction like this would normally be inundated... More
