Andre was an excellent guide and the knowledge he shared added enormously to the experience. The volcano sites were spectacular. He even provided a cheese treat at the end. Recommend this tour and tour guide very highly!!

Going inside a volcano was awesome. Such beautiful sights! Lots of stair climbing. Amazing how they were able to give people access to such a natural beauty. Entering the lava tube was cool too! Ground is naturally very uneven and bumpy, so wear good shoes. There is a bit of climbing too. Our guide Andre was very good. He provided us with lots of interesting information and he was very friendly. Obrigada!

Excellant tour. Vwry knowlegable guide. Not for people with mobility issues as at some points clearence was minimal and terrain was very uneven, rocky. Also had to descend to great depths and climb back up many stairs

An incredible experience I highly recommend. Andre, our tour guide was very knowledgable and was careful to ensure our safety as we explored the caves. Exploring inside a volcano is something that must be felt not something you observe from photos. Thank you Andre for making this tour so special. Margaret

Amazing unique geology that you should see. Paolo took excellent care of those in our party with mobility issues while explaining the sights to all.

This tour gives you a snapshot of visiting 3 different venues of past volcanic activity. Our guide Andre did a great job in explaining the history of the formation of the Azores.
