The Giant Sequoias hike on this tour is dependent on trail conditions and weather. Please be advised that weather, road and trail conditions in the winter make it less likely that you will be able to enter Tuolomne Grove to see the Giant Sequoias. Safety is the number one priority, so the route and itinerary may be changed due to snow depth, road conditions, construction projects and detours. Note that winter in Yosemite might extend from October into April.
