Returning from the caving trip, we found it to be very cost-effective. The instructor was excellent, taking many photos for us and providing a lot of information about stalactites and stalagmites. The chosen study tour was very safe, suitable for those with a fear of heights, yet fun, exciting, and full of a sense of exploration. There were very few people, and the caves weren't commercialized. Overall, we were very satisfied, and Instructor Yang was fantastic! 👍
