Hot Springs
The entrance to the hot springs is a massive cave opening, doted with holes and gaps that allow light to shine down onto the clean, slightly salted water. The hot spring is actually one massive pool that spreads around and down deep into the ground, getting hotter as it goes deeper. The floor is uneven, deep in some parts and high in others to allow for seating. The saltiness comes from the minimal amount of salt that is mixed into the hardened and polished floor from years of water traveling through it.
