How to get into the Divine Tower of Caelid
Situated at Caelid's Northern coastline, the Divine Tower here needs to be accessed with Parkour. Approach from the Southern side and ride or run up the giant roots alongside it, then jump across to the ledges and scale the building using the ladders and careful platforming - and be careful about the knights along the way! Eventually, you'll find the Divine Tower of Caelid: Center Site of Grace on a balcony. Use it, then take the West path around to a door with the central elevator beyond, which'll bring you up to Elden Ring Items the top for Radahn's Rune. You can also carefully descend to the tower basement, where you'll find a boss fight, so good luck!
How to get into the Divine Tower of Liurnia
This one proves a sticking point for a lot of people, and we can't blame them. Connected to the Carian Study Hall via a bridge, this requires you to get quite far through the Ranni the Witch quest. While you can wander in and explore at any point, you have to complete Ranni's questline at least partway to reach the top and restore the Great Rune.
We've put a guide on how to do that in our Elden Ring Ranni questline and secret ending - once you reach the fifth part of that quest, you'll be able to use a special item to flip the Carian Study Hall and access the bridge, though you'll have to watch out for a nightmarish hostile NPC and blob monster along the way. We recommend killing Preceptor Miriam (as horrible as she is, it's easier in the long run), but just run around the giant Godskin Noble on the bridge if you don't feel ready to fight him.
Of course, once you're up there, you won't get to restore any Great Rune, as the only Rune in the area is one you get for killing Rennala, and it comes pre-restored and ready to go. Instead, this serves as another point of Ranni's questline. So don't worry about getting to the top if you're not bothered about the Princesses' quest.
How to get into the Divine Tower of West Altus
One of the easier Towers, the West Altus Divine Tower is found by going into the moat around the capital of Leyndell and accessing the Sealed Tunnel mini-dungeon at its Southernmost point (the entrance to which you can see below). The Sealed Tunnel is practically a straight line, made up of illusory walls you can hack through.
However, there is a boss at the end called the Onyx Lord, one that's fairly weak to best site to buy elden ring items weapon attacks (a vulnerability that melee fighters can make use of). Once you've beaten him, you can access the outside door of the Divine Tower of West Altus - though if you haven't beaten Rykard, Lord of Blasphemy, yet, you'll get a message stating that it's "tightly locked shut". Once he's dead, you can open the doors and simply step on the elevator ahead to reach the top.
