The Central region of Hyrule is where Hyrule Castle stands, plus a lot of footpaths branching out in different directions. As a result, unlocking this Tower can be very helpful as you prepare to assault Hyrule Castle and defeat Calamity Ganon.
While the Tower itself is easy to spot and locate, being on flat ground in the open, it is surrounded by Guardians. They can even target you as you climb, making it difficult to ascend without getting a laser in your face. Attempting to Paraglide off the top after activating the Tower can also alert them.
If you are at the point in the game where you can safely and quickly defeat them, or if you have mastered the shield bash trick for using their lasers against them, then it is a better idea to dispatch of all the Guardians so that you can climb up and Paraglide off safely. However, if you do not want to engage them, and especially if you plan on fast traveling away, then you can run past them and climb as fast as you can.
As usual, you can bypass much of the challenge with a few well-timed uses of Revali’s Gale.
