I came for the adventure course/night zip line combo I found through Living Social. Entirely worth the full price. The adventure course was a challenge but not disheartening. I came away with a few bruises but the feeling I had accomplished something. The staff was excellent. Safety was paramount - seen both in the gear and in the quality of the course. The site was beautiful and I can't wait to come back in the spring. The jokes were horrid!
The zip line was amazing. This was my second zip line trip and my first night time trip. Again, safety was paramount. The towers were both functional and beautiful - kind of like Tinkerbell's Treehouse. This was probably enhanced by the fairy lights on the bridges and on the towers. This is a fun course, you'll need to be able to climb ladders, but you are always tethered to something so you needn't worry about falling.
I highly recommend River Riders based on these two activities. I'm looking forward to rafting in the spring.
