The cave was fairly short, but wide, the roof just low enough that he has to crouch slightly, and his hair still brushes it in places where it dips lower. It looks to be a quite old cavern, and leads fairly deep into the hillside, a steady drip, drip, drip of water guiding him deeper in. The floor is fairly slick, in places, though, so he'll likely want to take it slow, and make sure he has a way to keep his balance.
