The cave is filled with unique rock formations, including stalactites, stalagmites, columns, and curtains, created by thousands of years of dripping water, erosion, and other geological processes. The temperature inside the cave is a bit colder than the outside making it a nice place to visit in summer.

Team Nicerio visits Toma Limestone Cave

My family and I visited Toma Limestone Cave for the first time last September 17, 2022, during our 3-day Respect for the Aged Day Road Trip. It was also my 46th weekend as an ALT under the JET Programme. The cave is in the outskirts of town and it was a bit of a drive from the town center. Regardless, the drive was worth it as the cave was well-lit and had well-preserved (protected) stalactite and columns.
