    This is a fun and unique activity to see a tunnel left behind by the lava thousands years ago. The guide is friendly and explain things very well. The tour is a bit less than 1 hour. Most of the walk is relatively easy and not very long, not physically demanding. I didn't know inside the cave is rather camp and cold (around 6 degree Celsius) on a relatively warm day (17C) when we visited, so proper clothing is advised. I gave it a 4 star mainly because compare to other activities in Iceland you can do, I find this one more towards the expensive side.

    The lava tunnel was very interesting - various colors and types of stone and formations, etc. The guide was quite informative, personable, and humorous. The tour was worth the money. The guide even took everyone's pictures at the end (with their own phone or camera). Dress warmly - it was about 4 degrees Celsius (39 Fahrenheit) inside the tunnel. The only reason I didn't give this 5 stars was essentially because of others in our tour. They kept taking pictures instead of keeping up with the group. The guide had told us she'd stop during the walk in 3 times to explain our surroundings, and that on the way back we could leisurely take pictures. Unfortunately she waited for those taking pics on the way in, which was aggravating to those of us who followed instructions.

    Unfortunately we arrived too late, but it was absolutely no problem to move to the next appointment. The lava cave is worth a visit. You do not even believe how nature can fascinate you. Our guide was really entertaining and made the whole thing even more exciting. Only the price could be a tick smaller for the walk.
