Fodor's Expert Review Ialomicioara Monastery and Cave

Within Bucegi Natural Park, this pint-size monastery abuts the enormous cave, making it look even tinier. The monastery dates back four centuries, but the reason it looks in such good condition—you'll notice that the colorful paintings adorning its interior walls are particularly vibrant—is that what you see today was built 1993 following a huge fire. A guide will take you into the cave, which has 1,300 feet of accessible paths, so wear sturdy footwear. To get to the monastery, you can take the cable car from Busteni up to Babele and then hop on the cable car going toward Pestera (meaning cave). From there it's about a 10-minute walk.
