#mapyourmonday! Let’s go exploring some caves this week. This cave stretches for 31km and is located in a national park in Asia, which contains the oldest karst mountains on the continent. The national park was designated a Unesco World Heritage site in 2003. Quick – we’re looking for the name of the national park and the country it’s located in (bonus if you can tell us the name of the cave too!). Thanks @macandtherambler for sharing using #bbctravel.
