Hiking the Grand Canyon
It takes one full day to hike down the

Hiking down and back up in one trip is
not recommended because
dehydration or hypothermia can
occur.
It would take about one week to
make a full length river trip in a
motorized boat.
From the North Rim to the South Rim the
Grand Canyon is about 12 miles long.
A drive in the car from rim to rim would
take 215 miles and 5 hours.

water tends to be calmer.
The primary reason for building the
Glenn Canyon Dam was to
prevent silt from building up
behind the Hoover Dam.
The dam has actually had a negative
affect on the ecology of the area
because the water no longer floods
low lying areas, the water is colder
an native fish can’t survive the new
colder water.
