Ya Naga Shrine
The shrine may not be readily visible from afar because it's located in a depression in the middle of the island. The area has a handful of Lizalfos swimming and jumping between the islets.
Due to its geographical position and lack of altitude, the shrine doesn't provid a practical travel gate for regular use, other than for the obtainment of the Korok Seeds nearby. A more practical travel gate is the Lake Tower nearby, which overlooks most of the lake.
Shatter the Heavens
First, place a square bomb on top of the block. Then place a spherical bomb into the tube that is right in front of it. Blow up the spherical bomb first, sending the large block up into the area. Then switch over and detonate the square bomb when the block is near the ceiling. This will cause the bomb to blowup the boulders near the ceiling.
Then place another spherical bomb into the tube, and stand on top of the block. Detonate the bomb and it will send Link way up to the air. At the apex of the jump, use the Paraglider to land on the column on the right side to get a treasure chest that contains an Eightfold Blade.
- For all intents, the depression in which the shrine is located should actually be filled with water, as collecting water wouldn't have anywhere to drain to.
