Is there a height requirement? Or age minimum? I want to take my baby girl. She's 13 months

For the big pony rides (riding alone) yes. You can walk around with her in a smaller pin of horses (just goes in circles)

There is no height requirement, just age 1-3, 3-5, or 5-7 for slow medium or fast pony. Slow just walks slowly in a small circle w/parents inside a pen. medium is a slow walk alone around a track and fast is a quick trot around the track (each 2X)

there is but I don't remember how tall need to be
