There were drone shots from above DCHS in the show, and they even had some close ups of you Neo peering out from some bushes! Just kidding around of course
The one woman while soaking in the Anniversary Pool did mention the springs as being a clothing optional place, but they did not show any unclothed people. In the various shots it looked like a pretty quiet day as far as how many people appeared to be there, and the beach across from the hot pools was quite clean, with just the big fire scar on the granite seen. Made me wonder if they cleaned up a bit before hand as there is usually some measure of a pile of trash in that location.
