HAZARDOUS CONDITIONS WARNING FOR THE LOST COAST TRAIL: Visitors to the Lost Coast Trail have been faced with hazardous coastal conditions as winter storms wash over the King Range National Conservation Area. With swells frequently reaching heights above fifteen feet, an increased number of hikers have reported being caught off-guard and struck by sneaker waves (large waves which surge up unexpectedly). Sneaker waves can be hazardous, and all visitors are urged to practice extreme caution! Where possible postpone travel if inclement weather is predicted during your scheduled trip, as hiking along the Lost Coast Trail is not advised during winter storms.
Creek crossings may also be impacted as heavy rainfall swells them to unsafe depths and speeds. When attempting creek crossings always seek a safe point to cross that is well away from the ocean to avoid any sudden wave surges. For more information about the area, visit: https://go.usa.gov/xAh7n
