Wearing a helmet. At riding stables where you "rent" a horse for so much time, you will be required to wear a helmet. However, some riding stables will not require you to wear the helmet if you are of a specific age. I still recommend wearing a helmet at all times. Wearing a shoe with a small heel is also nice (no huge heels - "pumps") because your shoe will fit into the stirrup better. That is usually not required.
