Kern River Tours Inc at 2712 Mayfair Road, Lake Isabella, California.

5 stars!!!! They have exceptional staff!! Very knowledgable and experienced when it comes to river rafting!! We went through level llls and lVs with no problems. Our guide leaders were Sean and Drew and both were exceptional and fun!!! The location was perfect. We didnt need to take a little walk or take the bus to the start point like everyone else did since it was right in front of us. They also had an exceptional photographer to take pictures while we were rafting. We were not aware of that but at the end when we did see the pictures, it was worth buying them all.
We did the "SAMPLER" tour and was so worth it!! The water current was extremely fast and strong but was a good challenge since it was our first time. We did several level lVs and llls and because we had exceptional guides anyone who are first timers can do this... You just need to be ready and a good listener to do it!! :)
