It might be one of the first towers you find
The Eldin Canyon Skyview Tower in Tears of the Kingdom is one of the more straightforward “tower puzzles,” but given the game’s penchant for stumping people, I can see some folks missing out on it. Here’s where to find the Eldin Canyon Skyview Tower, and how to open it up for future use.
Where to find Eldin Canyon Skyview Tower
The Eldin Canyon tower can be found northeast of Central Hyrule, very close to where you end up after the tutorial.
The exact location is pinpointed in the map above.
How to solve the puzzle of the Eldin Canyon Skyview Tower
After walking up to the tower, you’ll notice an NPC, Sawson, provides a hint for how to open it up: “maybe if you used the terminal inside, that would force the door back open.”
In short, you need to climb to the top of the tower and fall into the cannon, down to ground level; then interact with the Sheikah device behind the gate. Once you do that the gate will open and the tower will be open for business.
When climbing up the tower, note the footholds in the middle that allow you to recover some stamina. Stop, take a breather, get a full stamina meter, then resume climbing up (hopping will swiftly deplete your stamina, so try and just take it slow and steady).
