Slide is a relatively short drain but I’d definitely recommend it, not because there’s crazy art or anything there; but just because it’s a bit wacky.
Make sure you wear some shoes with grip and if you’re with a group go up one at a time. When you get to the top its possible to exit from the main chamber. Don’t be like us and go back down the slide!
There is a smaller tunnel continuing from the main chamber however we did not go through it. After this we ended up going to abyss.
