Wow. Amazing spot. Easy to access. A mile long paved trail takes you to a wonderful viewing point. We went off the paved trail and hike for a couple hours up the mountain side. Tricky hiking but gorgeous vistas and complete quiet.
Both the journey and the destination are worth it. Hana itself is remote which is what makes it so lovely. Explore the bamboo forests and go surfing on isolated beaches. It's a hippy hangout and a nice trip.
