Dive into Earth's Pupil! Guangxi Sanmen Sea: A Karst Wonderland Rivaling Jiuzhaigou

"A sea within mountains, with doors upon the sea" — this isn't mythology, but Sanmen Sea in Fengshan County, Hechi, Guangxi, a "pupil of Earth" carved by karst landforms. Here, the water shines like blue tears, caves resemble sci-fi theaters, and the area holds the longevity secrets of a renowned region for long life. Every photo you take looks like a scene from "Avatar"! 【Core Experiences: Unlocking Three Dimensions of Geological Wonders】 1️⃣ Boat Journey Through "Earth's Pupil" Sanmen Sea is famous for its "7 pearl-like skylights." Riding bamboo rafts through them, watch as the water transitions from jade green to Tiffany blue. Sunlight penetrates the skylights creating "Jesus rays," while stalactites hanging from the ceiling resemble relics of alien civilization. Boatmen pole slowly through the water, with a 40-minute round trip visiting 3 open skylights. Every frame looks like God's spilled palette. 2️⃣ Paddleboarding on "Jelly Waters" Just 40 minutes by car from the scenic area, **Jiudun Skylight** is Guangxi's paddleboarding paradise! The crystal-clear water has 30-meter visibility, with underwater forests swaying with the waves. Professional adventurers can try cave diving to the 212-meter deep "China's Underwater Everest." 3️⃣ Hiking to Discover the "Longevity Code" Visit Bama Longevity Village (1-hour drive), meet centenarians, drink magnetized spring water, and taste hemp soup. Climb to the Baimo Cave observation deck to breathe in "air vitamins" with 30,000 negative ions per cubic centimeter, and experience the wonders of geomagnetic therapy. 【3-Day 2-Night Itinerary: From Hidden Wonders to Earthly Delights】 Day 1: Self-drive from Nanning → Boat exploration of Sanmen Sea → Overnight in stargazing bubble houses, falling asleep under the stars.
