We did do the horseback riding excursion through the rainforest and it was just OK. They do not have their horses go single file so the whole way they are jostling each other for their space in a free for all and you end up fighting them if you get a.... spirited one. My horse kept biting the other horses and running me up against other people and vegetation - my knees got pretty bruised up. My husband on the other hand had never ridden before so he got a horse that would barely go. I was in the front and he was in the back the whole time so it was a little lonely... They also did not warn us about the mud so I ruined my new sneakers which is probably my own fault I suppose. I didn't even consider it and the mud STAINS badly. I was very glad I didn't wear pants as they would have been similarly ruined.
There was no food or water although they did try to sell $2 bottles of water at the river stop. Its just a quick one to let the horses rest a bit - no one got in the water or swam or anything, it was pretty dirty there - a couple benches and an outhouse. I did rinse my legs off and try to clean my shoes a bit in the river though I just got them muddy again.
I am glad we did it - my husband knows he doesn't like horseriding now at least, lol - but we would not do this again and wouldn't recommend a newbie do it since the horses can be a pain to control. They trot and mine even went off at a gallop at one point which was a bit out of my comfort zone.... they wanted to get back quickly and kept trying to pass our leader which they weren't supposed to do.
OH! And someone was injured as well - his horse bit another horse and that horse kicked out and caught the kid in his leg. He was not badly hurt but it still DID hurt and he was bleeding from a cut on his leg. Just unruly is I guess how I would describe it. I'm not turned off of horses mind you, but I would not go with that place again.
