To get to the Cathedral of the Deep in Dark Souls 3, start from the Crystal Sage's ruins in the Road of Sacrifices area. From the Crystal Sage bonfire, take the left path up winding paths that pass two Butchers and an Evangelist by a pyre. Along this path, you can find several items like Twinkling Titanite and a Herald Set. Continue until you find a bonfire at the foot of a great stairway, which leads you to the main entrance of the Cathedral of the Deep. The entrance inside the cathedral is initially locked from this side, so you'll need to explore rooftops and alternate paths, including traveling through the graveyard area, to find alternative ways inside, such as accessing the rooftop entrance of the cathedral. Once inside, you'll face various enemies, explore the cathedral, and progress through the area.
Summary of key steps:
- Start at Crystal Sage bonfire in Road of Sacrifices
- Take left path passing Butchers and Evangelist
- Find bonfire at bottom of stairway leading to cathedral entrance

This will get you into the Cathedral of the Deep area to continue your journey in Dark Souls 3.
