Few years ago, Emily was terrified of horse. Never has enough courage to ride. It's probably too intimidating for her.
Besides horse riding, there are other activities available for the whole family.
Archery. You can play for a few sessions and pay as u play. Can't remember how much but it's not expensive. They offer archery lesson too. For member it's $60 for 4 session.
Trampoline. For the young ones. And the young at heart. Very good to destress ;-)
