If you go to Vortex, it is only about 12 miles south to Morrison Springs, which I like a lot better, and it’s free. No sign in at Morrison. Morrison has the caverns and caves, and I think the caverns are much better. Better facility all around. Bath house, covered pavilion, beach, board walk to a dive platform. Anyway, you could do both springs, which would make the trip more worth while.
Lots of rain will affect the visibility of the springs.
