I was very pleased with my trail ride at Pocono Adventures. First, they are the best deal in town, with prices that are about half that of other riding stables in the area. In addition, they use mules for the trails, which is a great improvement over the "nose to tail" boring horse rides that you usually experience. The trails are all natural and not prepared or cleared in any way. I've been riding horses for 30 years and I can tell you that a horse would never be able to handle that terrain. The mules definitely required more muscle to control, but you don't have to worry about them bucking you off or spooking at a falling branch. Their gait is also much more comfortable for the trail, especially on the two hour ride.
The guides were great. Their instructions before and during the ride were detailed and helpful. They were informative, humorous and very good riders. The guides and their animals know their jobs well and they do it right!
After reading some of the other reviews, I have to laugh at some of the supposedly "experienced" riders who complain about the mules' behavior. I guess if you hop on a broke horse and ride around a ring, it doesn't really prepare you for riding the trail. As a matter of fact, there was an allegedly "experienced" rider on our ride and all she did was complain about not being able to steer the small mule she was riding. After watching her for a while, I didn't really see anything in her technique that impressed me much!
I highly recommend this ride for anyone. If you are a novice, its a great way to learn. If you're an experienced rider looking for a trail ride that is actually challenging and fun, this is the place to be.
