Twin Bays Stable

Twin Bays Stable is located on Great Island in Darien, Conn. surrounded by the Long Island Sound. The iconic 25-acre private equestrian property belonged to the late William “Bill” Steinkraus, a pioneer in the show jumping realm and five-time Olympian.

Owned and operated by Kim Mulligan, a professional with more than 30 years of experience, Twin Bays Stable offers an 18 stall barn inside a stunning stone building with an attached 60′ x 175′ indoor heated ring and new footing.

In the spring, summer and fall, riders practice outside on grass jumping fields — perfect for competition on the same terrain. Also part of the facility is an outdoor sand ring with new footing and an exercise track that encompasses the grass field.

On hack days, riders can enjoy several trails that lead through woods and down to the shoreline, or across the causeway. Great Island’s residents all know to drive slowly and watch for animals large and small.

What began as a love of horses, has turned into a life-long passion. In the saddle, Kim is a fierce competitor, focusing primarily on jumpers, including at the Grand Prix Level. When she’s not riding, she is helping clients of all ages and ability to realize their true potential.

Twin Bays Stable has successfully trained riders in the hunter/ jumper and equitation rings — from short stirrup to Grand Prix. While Kim’s students have earned top honors in highly competitive show arenas (regional/ zone/ national finals), she is always happy to work with anyone who willing to learn. Her ultimate goal is to have each of her students become safe, courteous riders with a lifelong love for horses.

Twin Bays Stable is named after her first two horses, Ruby and What, both dark bays. Even now, many of the horses in the barn are bays, of course, with a few exceptions! Kim keeps her retired horses close to home so she’s never too far away for a treat and a pat.

The art of matching horse and rider is a critical element of a successful equestrian experience. The first step is to assess a rider’s ability, goals, and limits. While sometimes we have horses available for sale or lease within the barn, the perfect match might live outside the barn — whether in Connecticut, South Carolina or Florida. Kim will use her expansive professional network to source the perfect horse or pony to match your level of experience, commitment, riding style, and budget.



Hemingway available for half lease at TBS or full lease. Honest , brave, sweet personality. Good for someone who wants to do 2’ up to the 3’ eq/hunter/jumpers. Contact Kim Mulligan ( for more information.

We believe that learning never ends and often host clinics throughout the year. Most recently we had Ken Whelihan on site.

A former rider and trainer for Lionshare Farm and the Ox Ridge Hunt Club, Ken is the resident trainer for the Berkshire Equestrian Center. Everyone always appreciates his knowledge and input as a trainer, rider, and big “R” judge.

MA Licensed Riding Instructor/ Trainer Ken’s extensive knowledge (experience) judging, competing and teaching uniquely positions him at the forefront of the field. A Licensed Massachusetts Riding Instructor, a veteran grand prix competitor and trainer and a USEF judge of hunters and equitation for over 19 years, Ken qualified for and competed in the 1992 Olympic Selections trials for Barcelona at Gladstone and Devon.

During his illustrious career, he produced Zone 1 USEF two-time Horse-of-the-Year, “Tanglewood,” regular working hunters; rode Zone 2 USEF Horse of the Year, “Ramsey” regular conformation hunters; and rode and produced over a dozen jumpers to Grand Prix including Rashnu, Ballybay, Lucky Again, Ashe, Skip With Me, Tango, Ballybay Nightcap and others. Additionally, Ken coached riders to wins at the Marshal and Sterling, New England and Connecticut finals.
