Lake Hylia

Lake Hylia features most famously in Ocarina of Time (although is it also seen in several other games). It is the largest body of water in Hyrule, and is commonly relevant to the Zora people.

In Ocarina of Time
In OoT, Lake Hylia is a vast lake containing a hidden temple that goes by the name of the Water Temple. You can use the Iron Boots to sink to the bottom of the Lake to discover a few secrets (the Zora tunic is also recommended). On the shore of the lake there is the Observatory, which is home to an old man that watches you when you dive in his oversized tank. Many Guays roam this place, and can get very frustrating when you're trying to get somewhere. Also on the shore of Lake Hylia there is a scarecrow named Pierre who helps you obtain the Scarecrow's song. There is also a fishing hut, where you can fish to your heart's content for only 20 Rupees a time. You also you obtain the fire arrows from here at a point in the game.



In Twilight Princess
Lake Hylia, as home of the Lanayru Spirit Spring and Fyer's Cannon Rides, has changed much since its debut in Ocarina of Time, and has been adapted to handle the rigors of Twilight Princess. The Lake is also home to the underwater Lakebed Temple, similar to the Water Temple in OoT, and with that, the final Fused Shadow that Link must collect to continue on this journey to rid the land of Hyrule of twilight. It is here that the final Fairy Tear is fought for from within a gargantuan light bug, and the Spirit Lanyru is rejuvenated from the depths of the Spirit Spring. It is here where Link can hop a ride to the Gerudo Desert from the cannon of old Fyer, and visit with the Hylian ally Auru to learn of the demon within the Arbiter's Grounds to the east. The Great Bridge of Hylia strafes the core of the lake from high above and is the location where Link triumphs against King Bulbin in a makeshift jousting match. Lake Hylia is home to three Heart Pieces and is the prinicpal area that Link can recieve the Clawshot for the first time (from within the Lakebed Temple).
