At the South Rim, temperatures will range from upper 30s in the evenings to low 70s in the day. At the North rim the 30 degree lows and 60 degree highs have turned the Aspen yellow. This is the time to revel in exploring the many creeks along the inner Canyon trails. The narrow dark canyon of Phantom Creek and the Phantom Creek Wilderness area is cool and delightful in October. And the mineral caves beneath Ribbon Falls beckon hot hikers to sit under them.
Winter is the season of solitude and silence.
Fewer tourists travel the South Rim and below the rim, even the larger campgrounds are quiet and still. Temperatures at the South Rim range from 18 degrees to 41 degrees. While in the Inner Canyon the temperatures can range from the high 30s into the 60s. When the sun shines in the Canyon, you can hike in your shirt sleeves. In fact, every time has its own special beauty in the Canyon.
