I'm a quiet experienced horserider myself. But I have had a severe accident at high speed a few years ago, and I'm scared at very high speed. The 2 guys who were with me on the tour could cross over the beach, the guide did really care about me and stayed a little behind with me so I could canter on a more steady speed. It made my experience wonderfull! I have never been horseriding on the beach and I loved it, thanks to my wonderfull guide! But experience is required!
