All I can say is OH MY GOD!!!!! WE HAD A GREAT TIME. This year I did a 3-day trip with a friend, but last year I went twice: once for a one day trip, and then again of an over-night. The food is fabulous, the guides help with EVERYTHING, and that are all so knowledgable about the area as... More

I had booked a 1 day Tuolumne River White Water excursion for my son and I. Approximately 3 months before it was due I injured my back. I contacted Marty from Sierra Mac and explained what had happened, but as this was part of a grand adventure from Australia that I wanted to leave the cancellation to the last minute... More

Spent the day on the main Tuolumne River with Tom McDonnell as the guide, 6 of us in the boat, and had the best day. Lots of splashing going through the rapids, he was great getting us to row together, saw a bear and river otters, what a treat. The lunch was outstanding getting to make your own gourmet wrap...

We spent 3days and 2 nights rafting with Sierra Mac. Our guides, Scott and Joe were incredible, friendly and so knowledgable about the river. The scenery was breathtaking. The rapids fun and exciting and the food was fantastic. This trip was well planned by Sierra Mac. The best part of our trip was the lack of electronics and communication with... More

Marty McDonnell pioneered commercial rafting on California's Tuolomne River (fondly called the "T"). This is one of the most scenic and dynamic whitewater trips in California and once again did not disappoint us. My sons and I have run the T probably 10 or 12 times over the years, mostly with Sierra Mac. Why? Because we love running the T... More

An amazing day out! Stunning scenery and loads of wildlife spotted in between thrilling level 4 and 4+ rapids. On the quieter stretches of the river the guides are constantly scanning the sides of the canyon, and we spotted a black bear making its way back up the cliff-side, a bald eagle adult and chick, and a bob-cat. Our guide... More

We spent the day white water rafting on the tuolomne river with Sierra Mac. It was very well organised. The driver and guides were excellent. The groups were small - there were 5 in our raft. Lunch was delicious. This was one of the best days of our holiday. I highly recommend using Sierra Mac.

All Sierra Mac staff are very helpful, safety oriented and friendly. Our guide Tommy was not only a true pro steering our boat but also great fun, two teenagers on the boat had a blast. River Toulumne was just perfect for our taste, enough of challenge and you could really see the power of the water, yet we felt safe... More

Excellent service and attention, great guide (Hi, Mikey!). We had never done any whitewater rafting, but the guys at Sierra Mac made us feel totally comfortable and capable. We booked a one-day on the Tuolomne river, lunch included. Awesome team, all the guides made it very special. We have definitely gotten the bug, thanks again to the folks at Sierra... More
