Hired a car to work our way around Lanzarote and planned in a trip here with no expectations. We arrived just after 15:00 so our entry was discounted to 8€ each and this was well worth it. A small wait outside the cave whilst group numbers built up before heading into the cave with a friendly and informative guide who provided just enough information without it becoming boring in both Spanish and English. You make your way through the fascinating cave system and ending with a final acoustic test - “the secret of the cave”. This was a fantastic activity for a bargain price.

Visited this on a bus tour with a multinational group of mostly elderly people. The guide warned us that the path through the caves might be uneven. A few people with walking sticks sensibly decided to remain behind having had trouble negotiating the rather steep slope to the entrance! As it turned out, the paths underground were fine, and any danger came from the very low roof at several places. This necessitated bending double in a badly lit tunnel. Why can't they simply paint these parts with white paint. If you're able to walk freely, elderly or not, it's fine underground. The attraction itself is worth seeing. The underground lava tunnels and enormous natural caverns are surprisingly extensive. I was expecting it to be chilly, but the temperature was good. We ended up in a very large amphitheatre which is used for concerts because of the excellent acoustics. That would be well worth experiencing. The highlight was an enforced stop near the edge what looked like a massive drop to the centre of the earth. The guide made a big drama of making us all stand safely back while she ventured forward to toss a loose rock over. I'll not spoil what happened. You'll need to take the tour.

Brilliant! Really enjoyable, really informative and how often do you get to walk through a tunnel in a lava flow? €10 very well spent. I would recommend that if you are taking yourself here - probably go to Jameos Del Agua first, as it seems to handle queues and capacity a bit better, and then go to the caves (on the same day) later in the day. They are 2 minutes apart in a car. You will be grouped in to about 50 people and then you are taken in with a guide, and there are two staggered groups in at the same time. This does mean (if it is busy) you could be in for a bit of a wait. We found that at after 2pm (or better - around 3.30pm) you'll find the smallest queues.
