We had a great experience with Mudkat. Their website was clear and it was easy to book a rental. We chose to float down the river and since it was a Sunday morning, we ended up being the only folks on the river for an hour or two. The entire float took about 3 hours.
The guys that run this place are friendly and know the area well. They seem to really enjoy what it is they do. We're planning on booking with them again next time we're in the area, maybe a kayak this time.
We loved it hereQ I was nervous after reading some other reviews around the internet, but our little cabin (#4) was recently re-modeled and had everything we needed. It was clean, cool, and conveniently located near the center entrance of Shenandoah National Park.
The cabins are not set deep into the woods. They're right off a road, but in the evening it's quiet; not much noise from cars. Next door is a small restaurant; it's a great spot for breakfast or lunch.
This part of Berkeley Springs is a great stop along 522. We always like to stop and dip our toes in the springs and hey, there's George's bathtub, too.
