Where do you find ravine in Minecraft?

In desert biomes, ravines can be hidden under sand blocks. When a player walks over these sand blocks, they will start falling and die as a result. Using elytra or horse is a better way to explore them.

How rare is it to spawn in a ravine in Minecraft?

It is relatively-common to find up to around half a dozen canyons intersecting close even to where they're first found (including vertically, often perpendicularly). So if one finds one, one may find more, soon-enough.
