As soon as you have spawned you will notice you are in a village. The surrounding area consists of mostly plains but there are some extreme mountains and lava behind you too.
Go to the center of the village and find the well. Jump in the water and dive to the bottom and then mine down from there. As you do that you will drop down into the beginning entrance of a stronghold.
The stronghold will look similar to other strongholds with chests and an end portal room.
