Another idea that our family members have enjoyed is a trapeze class. Check Groupon or google The Trapeze School of New York (they have branches in other cities).
My S has also enjoyed a race-track experience when he was younger (riding in a race car going more miles per hour than I care to remember) and for his most recent birthday a family member gave him stick-shift driving lessons as he wants to learn how and we don’t own a stick shift car.
