The hike is quite easy and the caves are interesting. But most important, you should do the cave part as a circuit. When you see the caves, you should continue along the valley. Then you will gain some elevation and follow a trail leaving you to the caves.
Feel free to check out my video from when I visited the caves to see what it is like
Start at 4 minutes into the video, and go until 5.30 for the Bone caves part of the video.
