Yes. It’s bear country; carry bear spray, make noise, travel in groups, and follow safety protocols.
Backcountry camping permits are required for overnight stays and some activities; day hiking may not require a permit, but verify with the Backcountry Office.
Very limited; expect spotty to no service on most portions; Verizon may be strongest near developed areas.
Estimate 6–8 hours for most hikers, depending on pace and stops.
Not mandatory, but essential for a safe one-way hike; arrange a shuttle or two-car plan in advance.
