Open Door Experience with waterfall

We took the open door with landing at Jack's lava house. It was a very neat experience getting to walk on the lava rock. Be prepared for being wind-blown on the open doors, and take a jacket as it can be chilly in the air. Overall a very nice experience, but don't expect big "red lava flows" as that is not realistic. You can't exactly "feel the heat" and the waterfalls are not close up views they are more from a distance and thrown in at the end, But still pretty spectacular scenery!
