The caves and lake were pretty cool, but the whole place is a bit tacky. I guess that's to be expected. I learned some interesting stuff, but would not go again. More

The Lost Sea Adventure is a good attraction and different to your usual cave trip. It is a fair but easy walk underground to the lake but it is worth it.
