Green lake is just one of the sites on the Palace tour. You can see part of it if you know where to look on the Natural Entrance tour. The small lake is very clear as are all water areas in the cave.

The Green Lake is part of the King's Palace tour. Since Carlsbad Cavern doesn't contain large bodies of water, this is a cool sight. Reflect was very pretty.

Green Lake is one of the first features you'll see in Carlsbad and about the largest area of water you'll see in the cave. Some may be underwhelmed, but if you like caves you'll like Green Lake.

This is not the most exciting part of the caverns, but it's nice nonetheless. The lack of water in the caverns is an interesting fact, but you won't know why there's so little water unless you do a bit of research before your visit.

We saw this little pool of water at the kings palace tour. It's absolutely beautiful. It fits perfectly as part of the tour. We loved the reflective water. It's about 8 ft deep.

Due to the incandescent lights that used to be used in the cave, there is a lot of green stuff growing on rocks, etc, that the Nation Parks hopes will stop growing since they've switched to LED lighting.

Amazing clear water with just enough green tint. Worth stopping on the trail to view. Nice to see it has not been a receptacle for coins or trash!
