Rapids Ride

Rapids Ride is a region located in the eastern part of Koholint Island from Link's Awakening. For a fee of 200 Rupees, Link would be able to travel on a raft down a series of high-current rapids and waterfalls. Link could obtain items floating above the rapids, such as rupees, arrows and bombs, by leaping with the Roc's Feather to catch them. The rapids also serves as a shortcut for getting from the northeastern to the southeastern parts of the island.

Twilight Princess
Iza's Rapid Ride, or just Rapid Ride, is an event that takes place in Twilight Princess, and is located in Upper Zora's River, in Lanayru Province. It is run by Iza and her Zora friend. To get to it, Link must have access to Zora's Domain.

If Link speaks to Iza, she will simply ignore him. Walk around the area beside the fishing hole as human Link and soon he will be attacked by Shadow Beasts. Defeat them, and Iza will let Link into her hut. She will request that Link help her out by clearing a path downstream. If he agrees to clear the debris that has clogged the flow of the river, she will lend him a bomb bag and fill up his quiver with arrows. Shoot the rocks visible from the hut's interior with bomb arrows twice, and Link can get into a canoe. About halfway down the River, Iza's Zora will appear, and ask Link to blow up a rock. Do it, and Iza's Zora will guide Link the rest of the way(she will leave a trail of water ripples and Rupees). Get to Lake Hylia, and the Zora will let Link keep the Bomb Bag Iza lent him.

Later in the game, return to Iza's hut. This time, Link has to smash pots that he sees using bomb arrows (yellow ones are worth 1 point, red ones 2 points). Score at least 25 points by the time Link reaches the Lake, and the Zora will double his bomb capacity in all bags that he currently has, and all bags that he receives in the future.

Link's Crossbow Training
The Rapid Ride appears in Link's Crossbow Training. Link will float down the falls and shoot Tektites, Toadpolis, Jars and a Scarecrow.

Trivia
Inside Iza's Hut, there is a yellow pot that can be destroyed with bomb arrows. Destroy it, and Iza says to stop destroying her stock. Do this again, and you have to pay 10 Rupees.
