We went for a hack on the beach at Holkham - which is on teh North Norfolk coast this lunchtime.
It costs 10 pounds to park your horsebox in the carpark and they supply you with a map which shows where you can go.
You ride through some pine woods on a special track then through the dunes onto the fantastic beach which is massively wide and flat.
We rode for ages across running streams etc until we got to the water (high-tide had been at 10.45) and then the connemara was encouraged to go in. She was reluctant at first and then didn't seem to want to come out of the waves! Here is a short video link
It was a warm and sunny day by my word it was incredibly windy which got the roan sec a revved up.
Definitely worth a visit for anybody who fancies a beach gallop and can get up there.
