You will find fewer trail signs and markers. Wildland Areas are also accessible to hikers. These are areas where there are no trails, campgrounds or any other facilities. Campfires are not permitted. Expert route finding skills are required if you want to venture in to these areas.
Water levels are also at their highest due to spring run-off.
Trails are muddier at this time with spring melt, and June being the month to receive the greatest volume of precipitation. Towards the middle of July mountain passes should be open. Although conditions are drier from September to mid-October, temperatures are lower with greater chances of snowfall occurring, particularly at higher elevation. Regardless of what time of year, prepare for all-season travel. Your safety is your personal responsibility.
