Trailer Parking Policy

Blenheim EquiSports is pleased to provide trailer parking for exhibitors during the show weeks in which they are entered.

However, The Riding Park facility is home to many events between horse shows and parking space is extremely limited. As such, exhibitors are required to remove all trailers and other personal property from the park by 10pm on the final day of the show in which they are entered.

If you would like to make a request to keep your trailer on-site after this time, you must obtain authorization from Blenheim Facility Management, sign a release waiver, and pay $75 per week.

A request is not guaranteed until approved in writing and payment is received.

Approved trailers must display a valid parking pass affixed to the license plate of each vehicle.

Unauthorized vehicles will be towed at the owner’s expense.

To apply for a parking permit, please contact Vendor Relations at:
