260 Mountain Trail Lane, Acme, PA — a 54.3-acre equestrian estate in the Laurel Highlands of western Pennsylvania, currently home to Stoneybrook Foundation, Westmoreland County's only PATH International Premier Accredited Therapeutic Riding Center.
The property is offered for sale with exceptional operational flexibility. Stoneybrook Foundation — a well-established, mission-driven nonprofit — currently operates from this location and has expressed a genuine willingness to work collaboratively with a new owner. Depending on the buyer's vision, arrangements may include a partial lease, a negotiated occupancy agreement, or a clean transition in which the Foundation vacates upon closing. There is no adversarial dynamic here: Stoneybrook Foundation fully understands the property is for sale and is committed to facilitating a smooth outcome for all parties. This gives a qualified buyer rare optionality — the ability to acquire a fully operational therapeutic riding facility and choose, on their own terms, whether to continue that legacy, partner with an established program, or reimagine the property entirely.
PATH International Premier Accreditation
Stoneybrook Foundation holds PATH International Premier Accreditation — the highest recognition level achievable for equine-assisted services centers. This credential certifies certified instructors, documented equine welfare protocols, accessibility compliance, and safety standards that rival clinical facilities. It took years to earn, it cannot be purchased, and it represents meaningful value, healthcare network, equestrian investor, or nonprofit seeking to expand therapeutic programming in western Pennsylvania. No comparable PATH Premier Accredited facility exists anywhere in Westmoreland County.
The Equestrian Facility
The professional-grade equestrian complex includes 23 horse stalls (10×10), an 80×110 indoor riding arena with 500+ hay bale storage capacity, nine electro-braid fenced pastures, additional three-strand fenced pastures, and a 52×72 pole barn. Every structure was developed and maintained to support therapeutic riding operations at scale — with year-round indoor programming, safe turnout rotation across nine managed pastures, and on-site hay storage sufficient for full-year feed independence. Two handicap-accessible bathrooms serve program participants, caregivers, and visitors with mobility impairments.
The Residence
The 3-bedroom, 2-bathroom home provides comfortable, year-round living at the center of the working property. Features include a wood-burning fireplace, oil-forced air furnace with central air conditioning, full cinder block foundation, carpet, ceramic tile, and laminate flooring throughout, private water well, and septic system — a fully self-sufficient rural homestead.
Location — Acme, PA / Westmoreland County

The Opportunity
Whether you are an equestrian investor seeking a going-concern operation, a healthcare or nonprofit organization looking to expand therapeutic programming, or a private buyer envisioning a premier rural estate — 260 Mountain Trail Lane offers infrastructure, accreditation, and flexibility that simply cannot be replicated at this price point in western Pennsylvania. The Stoneybrook Foundation's cooperative posture makes this one of the most straightforward transitions available in the regional equestrian market.
