Not sure if it's still this way but there are two entrances to Mayfield Falls. Our driver took us to the old original entrance. The best in his opinion. The other place starts and ends at different points on the river (I think further upstream). Maybe someone can correct me if I'm wrong.

There is an entrance fee that gets you a cabana style place to change and keep your personal items. The guide will take your camera and look after it on the journey. Tips are a must for the guide. Be generous and extra generous if he's really good. Mayfield is a guided walk up a flowing river cascading over relatively shallow falls. Places along the way to dive, swim under rock structure, rope swing etc.. It can be a bit challenging for those with mobility issues. Very enjoyable and stunningly beautiful. It's really a great experience. But even the walk out is long and uphill. It's could be a bit exhausting for those not used to physical exertion. Not me of course.

YS falls on the other hand has a series of 2 or 3 cascading falls with a large fall that you can swim to and get under. Your going against the current so you need to be a reasonably good swimmer. There is a Zip line (I didn't try). There's also a concrete wading pool. Very beautiful area and an enjoyable and less physical excursion. It's been a long time but I think there was food available.
