Founded by Sylvia Martin as a training and rescue facility for abused horses, Bosque Circle Ranch teaches pupils how to ride and care for noble steeds. In a one-hour Western lesson, instructors pair students with one of the ranch's horses and cover such in-stable preliminaries as brushing, tacking, and checking for vestigial pegasus wings. After prepping horses, riders hop into the saddle for activities that include fun, educational games led in classes. Small student-to-teacher ratios are capped at three to one, ensuring individualized attention for each rider. Bosque Circle Ranch is open Friday through Sunday, and riders should call ahead to schedule a lesson. Horse lovers can also donate $5 to the Walkin' N Circles Ranch, which provides neglected and abused horses with a comfortable life of shelter, attention, and horse-size top hats.
