Cueva de las Maravillas
Cueva de las Maravillas is a La Romana natural attraction that takes visitors underground into a deep cavern. This cave is estimated to be over 100,000 years old, but it wasn't discovered until 1926. Inside its walls you'll find interesting rock formations and elongated stalactites and stalagmites that resemble icicles. These were formed due to mineral buildup caused by the cave's constant moisture. You'll also see pictures on the cave walls left by the native Tainos, an indigenous group that once had a strong presence in the Dominican Republic.
The half-mile-long Cueva de las Maravillas is an easy cavern to explore, as it has a concrete walking path and is well lit.
