A karst cavity up in the mountains near Las Guáranas, carved out over eons by water eating away at limestone. The name comes from the wild lilies (lirios) framing the entrance. Back in the day, it was a go-to shelter for campesinos (farmers) passing through; nowadays, it's a magnet for hikers chasing that natural AC deep inside and killer views of the valley.
