It should be mentioned that there are about three undeveloped
hot springs located in the Hoover Dam area, on the Colorado River. The
springs are actually over the Arizona border, in the Willow Beach area,
but are within a two hour drive from Las Vegas. These springs are accessible
by primarily by boat (land routes are difficult). You can rent boats
and some places will provide a map of the hot springs route.
The springs are: Arizona (Ringbolt) Hot Springs, this
is the only spring that is accessible by hiking. Gold Strike Hot Springs,
and Boy Scout Hot Springs, there are also sauna caves.
