Lake Totori is a location found in Breath of the Wild.
Lake Totori is a body of water that completely surrounds Rito Village. It is a fairly large lake with very steep cliffs on all sides. If a Hylian were to fall into the Lake, it would mean near certain death as there is nowhere to climb up. There are some air geysers throughout the area that Link can ride with the Paraglider to reach higher elevations.
There are numerous large islands found sticking out of the lake. The massive island to the northwest has a hole at the top that Link can drop in. Here he will find two statues with offering plates which, if both given an Apple, will reveal a Korok. There are a bunch of Luminous Stone Deposits in this area as well. The island to the west has a seed platform that creates a ring at the island to the south. Use the Paraglider to reach it in time to get another Korok Seed.
