You can use the alltrails app or viewranger app to download trails/ use as gps on your hikes.
Go to the visitor center, there you can get familiar with all the trails and enjoy fresh water. They have volunteers who are friendly and helpful
Water fountains would be great, and besides the cost, too many fools would ruin it for everyone...play safe and bring your own, and perhaps a little extra for a thirsty fellow hiker.
There are three or four benches on the trail to the top of the mountain
