I have phoned to check and the 7th November is free for the use of the XC course. Whether riding or on-line this is a great way of introducing your horse to various scary obstables including a water complex.
It is a great day out and you can stay for as long as you want for a one off payment.
Bring a packed Lunch and drinks and make a day of it...
Bring a towel if you intend of walking into the water and maybe a change of shoes
