Since the modernization of the caves it has become more difficult to access it not like the previous updates as it has become impossible to find a normal entrance to the caves in order to explore them, even after repairing them it is still very rare.

*The entrances to the caves are:
A large opening that leads to a huge cave (when you have started a new world it will be difficult to enter and mining even if it will be full of monsters)
Or a crescent-shaped entrance from the outside and then descending in a narrow slope and difficult to walk inside (which causes some resentment to the players due to the difficulty of moving in it and mining, especially in the beginning) it is closed or submerged in water
Very rarely do you find entrances in the form of ancient caves, even if you find them closed or submerged in water, and do not lead to other caves as deep as the previous ones. Or it may lead you to another exit, instead of going down and branching into other caves

You can enter any world in update 1.17 and you will notice how the entrances are spread out and easy to notice and find, and are connected and you can go down with them and find other caves connected together

There should be a variety between huge entrances and entrances from the caves of Noodles and ancient caves and enable you to reach other caves like update 1.17 instead of being closed or filled with water

In addition, you cannot find ravine from the surface like the previous updat
