The answer is dependent upon the maturity of your two-year-old. There are 126 steps in/out of the cave, which could be difficult for her short legs unless you carry. Our tour guides do the best to accommodate all situations That said, it was a great visit for my 3-year-old Grandson some 14 years ago.
We brought our 2 year old last year. She goes on every adventure with us. She's pretty tolerant and we'll behaved. We had some up and down moments (like how to change a surpise diaper during a guided tour in a dark warm and humid cave). Given the option, I probably wouldn't take her again, so no, I wouldnt recommend it. The staff was exceptional and tolerated... I mean engaged her and tolerated a couple "2 year old" moments REALLY well. She stayed in my arms much of the time, but our lesson was to take turns taking the tour so she could play up top while we toured individually. Hope this helps.
Might depend on how well behaved the child is. AND there are a LOT of steep stairs to go down that are NOT like a nice staircase in a building. Climbing back up can be tiring too!
A child that young might not find the cave entertaining.
