You'll have to check the laws at the beach where you want to ride. Most horses LOVE being ridden on the beach, but some get nervous the first time. I'd suggest riding on the wet, compacted sand. This is better for their footing and joints than riding on the loose, dry sand (especially if you're going faster than a walk.) Added bonus: Salt water is GREAT for a horse's hooves and legs!! If your horse will allow it, talk it out in the water.
It depends which beach.
Depends on the beach .and the people who owns it.
It is just according to the beach some beaches allow it but then others don't.
Check the law.Some beaches do some beaches don't.Because my friend has a picture of her riding a horse on the beach.I do not know which beach.Good luck!Hope I helped!
