Beautiful, the landscape is pure natural, magical underground dark river can be sightseeing by boat. There is also a strange geological phenomenon "calling spring and rain", that is, "calling spring", super magical! ... There is also the billion-dollar goose tube group, which is too spectacular. The crystal clear crystal tube is actually a calcified landscape of stalactites. It is really a world view! ! And the interpreter of Longhu Cave has a good service attitude and careful explanation. Worth a visit! Worth the trip!
