My sister and I did that excursion last year and we both enjoyed it and she had never been on a horse in entire life. The scenary was absolutley breathtaking - that alone is work the cost. The only drawback for me was the inability to take photos because they don't stop the horse and I didn't want to let go and fall off. However, if you are braver than I, perhaps this will not be a problem. And I must say the food was delicious. They also do a show during dinner that was delightful - I would most definitely recommend this excursion and I would do it again myself.
ps...the horses are very calm and I think a littler older. When I mentioned the fear of falling off - it was because the path is rocky, but my horse was delightful and knew where to put her feet...the horses are not to be feared, they are quite gentle.
Hope this is helpful
