Fantastic and intimate
, Nov 2019
Ivan led us on a stunningly personal and thorough tour of the cave and snorkeling. He was warm, courteous, patient, and funny. When my wife experienced some anxiety about tight spaces, he made her feel v comfortable.

Lava caving portion was canceled due to weather but was fully refunded. Was disappointed but can't do anything about the weather. The Silfra snorkeling however was awesome & our group leader Adam was super. He was funny & knowledgeable, made sure everyone was suited up & comfortable before going in to the water. Water was very clear for viewing & though cold wasn't too noticeable once in the water since you're suited up heavily. Overall great experience & would highly recommend!
