A self guided, 5 mile float on the Truckee River from Tahoe City to at, or near, the River Ranch.
You can use your own raft, but this can be a transportation issue...once you float down the river...how do you get back to your car?
There are companies in Tahoe City that rent rafts, and transport you back to your starting point after your trip down the river.
Each of these raft rentals pick you up, at the end your 5 mile float, somewhere near the River Ranch. At the River Ranch you can have lunch, drinks or just enjoy the view. You can, then, catch their free shuttle bus back to your car.
