You have a choice of places to ride and I'd recommend Turtle Bay.
Fantastic leisurely ride fit for novice and intermediate riders. The ride up the coastline of Turtle Bay's huge 800+ acre resort is amazing. The guides even point out a sweet place to snorkel. There aren't many fish close to shore but if you go out a little you'll see some fish along with turtles.
Guides were fantastic and provided lots of interesting along the way including telling us about all the famous celebrity horses you're riding. One's from "at close range". A few horses have been on TV shows.
