We were here in mid April to complete our open water certification class, and I had no idea what to expect (for obvious reasons).
The facilities were definitely adequate. There is a large covered area near the water with picnic tables and such underneath was nice as well, although I would have appreciated another entry / exit point near the water. This goes quickly, but there are also several picnic tables closer to the water, most of which are situated by smallish trees that provide a bit of shade during the day. I would suggest bringing a tarp for your gear because the ground is pretty sandy out there. The restrooms aren't too far of a hike from the spring itself, and are located in close proximity to the main office / dive shop. The bath house with the three (blessedly hot) showers, however, are a bit further out... but not too far that I didn't take a hike over there to warm up between dives on our second (windy) (colder) (rainy) day of diving. Both of the restroom / bath buildings are exactly what you come to expect from campground type places - concrete, a little sandy, most everything is working but it's a little run down, décor is either nonexistent or has a kinda home-made kitschy feel to it. I didn't see any spiders, though, so I was cool.
The spring itself was a lot smaller than what I was expecting. There were stairs with handrails for water entry (although the right side of the wooden set we were using was a little too steep for my comfort), which was much appreciated. There are also several concrete platforms for divers to hang out and check out on skills (it's a popular place for the checkout dives it seems), as well as a swim-through and a talk box, a couple of rings for working on neutral buoyancy, as well as a couple of ascent lines with buoys. Gravel bottom for the most part, with odd hose-type things running all over the place, and LOTS of green algae-ish type stuff everywhere. On our first day of diving, this crap was so thick in the water that our visibility was severely limited (like10ft-ish) due to all the divers in the water stirring things up all day (we dove around 230pm from what I remember?). From what I understand, they have a filtration system to try and cut down on some of that stuff, and also a guy that works to maintain it as well, but there's only so much you can do. The second day was actually pretty nice -- we were there waiting when the shop opened up at 7am and we wanted to get checked in, in the water, and get our dives done before the severe weather started rolling in. And because of that forecast, there were hardly any people there, which made the water conditions ridiculously better. We could see plenty of fish swimming around (fun!) and visibility was muuuuuch better. Even so, I still got myself turned around on our last dive (which was a plan-and-execute-yourself kind of deal). The water is a cool 68 degrees -- I am cold-natured, so even with a 5mil 2-piece wetsuit on (which means 10mil on my core), I was still a little chilly while we were just sitting around on the platform while the other folks in our class did their skills. It definitely gets dark down in the cavern area, so make sure you bring at least a small light even if you're not planning on going into the cave itself. The dive store sells feed for the fish from what I've been told, and then fish themselves are definitely not people-scared as a result.
Bottom line - this was way more fun than I expected, and the facilities were definitely up to par. I'm more into nice warm water and tropical fish, but I was kind of surprised at how many different fish we saw (including a few koi near the edges early that morning) and how neat it was to poke around on the 2nd day. If you're coming here for a fun dive and not classes / training, I would avoid doing so at peak times -- you won't see a thing due to all the crap being stirred up in the water by inexperienced folks (like me, ahem). read more
