Very relaxing and beautiful place. The landscaping is very well done. I almost forgot that I was IN a resort. The force of the water flowing over the rocks is amazing. There are beautiful and strong waterfalls to sit comfortably under. The feel of the warm volcanic water flowing over your body is amazing. The temperature of the water is perfect, Of course, these "waterfall" spots are popular, and it can get crowded at times, but almost all the hot springs there are large enough to seat many people. There are other pools with varying degrees of water current flowing. I did not find any very deep, but some very shallow. The volcanic sand was pretty soft--no need for water shoes unless you want the traction which helps getting in and out some of the springs. But, it seems like a very safe place. Perfect for families of most ages. There is a lovely area for adults only. It offers more privacy and a lovely area of beds near a large hot spring pool. Soft music plays in some areas, setting a romantic and relaxing mood.
For children, there is a water slide and large pool, closer to the restaurant/bar area. I don't think that is part of the hot volcanic springs, but it is nice for kids old enough to swim in.
Be aware that there is a deposit for a towel This is extra. Not a cheap place, but you can make it less expensive by not eating there or purchasing drinks. And you can come half hour or so before sunset and pay reduced admission fees
