I understand the kennels are located in a wilderness setting. There are natural hazards that include rattlesnakes and wildfires. While we do our best to mitigate these hazards by removing all rattlesnake habitat and being alert to the area, this is part of Yosemite's landscape. We will always have someone present at the kennels as well. Click yes, if you have read this information and want to continue booking. If you choose no, we cannot move forward with your reservation. We do not normally have issues with rattlesnakes but they do live naturally in this elevation as well as in Yosemite Valley.
