The world's largest electric submarine.This Atlantis submarine is not a semi-submarine like any other island tour, it's a real submarine! The deepest can dive to a depth of nearly 50 meters, and can take 51 passengers to the bottom of the sea at a time. Taking a submarine is a very special experience, many people may have a chance to experience it, those who want to try it or those who are afraid of diving can try it.? The whole trip takes about 3.5 hours. You must first take a bus to the dock and then transfer to a barge from the dock to reach the submarine. The ride takes about 35 minutes and includes a pre-recorded Chinese commentary that can be listened to on the ship's headphones. There are lots of fish along the way, which is educational, and you don't have to worry about the pressure of the boat.
