Our tours operate rain or shine. Rainfall is generally very short lived, and may offer the chance for you to see rainbows or waterfalls over our famous mountains. We do carry rain ponchos and umbrellas on the vehicles in case of inclement weather. In the case of extreme weather, Highland Excursion and/or the US National Forest Service reserves the right to modify, shorten or cancel any tour to prevent damage to trails or avoid unsafe conditions.
