The state park museum has very interesting historic displays and, of course, a little gift shop. It doesn't take a very long time to go through it and you can learn many interesting facts about the town. There are videos and panoramic photographs, artifacts of all kinds and sizes. I really enjoyed it. It was very relaxing after all the hiking we did during our first few days in the Sedona area.
After we visited the state park we went into town to look in the shops and have lunch. There are only a few streets and they climb back and forth across the side of the hill. Not too hard to walk if you pace yourself.
We had lunch at The Haunted Hamburger. It is a restaurant and bar that has very reasonable prices, good service and good food.
Some shops have a lot of the same things you see in all the tourist stores all over the place. There are also a lot of shops with unique items, locally made arts and crafts which are moderate to high priced. In my humble opinion it is worthwhile to visit Jerome.
