The group of twelve that camped behind us said they were staying two nights but loaded up and left about 3:30 p.m. the second day. It was really interesting to watch them. I would have been very uncomfortable launching a group of that size that late in the day, but it seemed to work for them.
Unlike when we first started paddling this section of river, there is now a 32 page guide book printed on waterproof paper that points out many of the highlights. It's also available as a large pdf file from the Boulder City library.
We took out below the boat ramp at Willow Beach Marina. (about River Mile 52.5)
This section of the river was recently highlighted in Backpacker Magazine. Unfortunately, that article had lots of incorrect information.
This section can also be paddled upstream, launching from Willow Beach Marina, saving the cost and missing the experience of launching at the dam.
If you want to launch at the dam, I highly recommend our friends at Desert Adventures in Boulder City, NV or Desert River Outfitters in Bullhead City, AZ.
