What I love about this tour is how seamlessly everything is arranged — the private round-trip transport makes the journey stress-free, especially if you’re traveling with luggage or want to avoid public transport. The cave visit itself is a highlight, packed with fascinating geological features and little surprises along the way. Plus, the tour includes a guided commentary in English, which makes it more engaging and educational.
However, a word of caution: the cost of entry isn’t included in the base price, so you’ll need to factor in that extra fee.
