I was interested in going horseback riding along the beach while in Hawaii.
Does anyone know of a good company in either Maui or Kauai that does this?

I just watched the top 10 beaches in the U.S. on the travel channel and the number one beach was Poipu Beach on Kauai. It showed horseback riding on the beach. A helpful website is www.poipu-beach.org

We've used CJM stables out of Poipu before. They have a 2 hour ride where part of it is on the beach/along the ocean. Riders were grouped 6 to a guide and spaced so that you did not see the groups in front of or behind you. Our guide let us do some loping as well after he gauged our experience level. Prices were very reasonable for Hawaii standards.

Princeville ranch also offers options for various prices. There is another ranch on the North Shore, Silver something or other.

Just got back from Kauai and took a three hour trip with Princeville Stables. Our guide was wonderful - BUT, if you've any horseback experience, you'll be disappointed. The ride is strict, you cannot allow the horse to do anything but walk (not that they would want to - they are used to this), and it's a straight ride across ranchland. You'll see the ocean but not closely and there's a bit of a hike involved - down to waterfalls that are breathtaking - that they are not specific about. If you're not in good physical shape, it's tough (involves a bit of rock climbing and they do not tell you this ahead of time). For the price ($120 pp) it was decent, but as an experienced rider, I was somewhat bored.

Great feed back Sherl thought I had heard similar complaint about that bit down to waterfall somewhere else. Sorry 120 to me is a bit outrageous. Yes it is a beautiful but a rip off is a rip off. I went on the North Shore of Oahu straight on the beach last summer 1.5 hours for $35 dollars we did gallop for a short bit and there were other sessions for experienced riders where you could gallop more. Also we were in a small group of just 5 riders. Just seems like the North Shore Kauai activities increase every year and they try to take you for every last dime. I think I would die if I had to walk a horse for 3 hours.
