Diamond Hill is the landmark of Hawaii and an extinct volcano. The mountain scenery should be good. It's hard to find the entrance for hiking up the mountain. In the crater, you need to buy a dollar ticket through the Kahala Passage to get up the mountain. You can see the volcano is not far from the hotel or walk there. It took 50 minutes to walk from Wikikipedia to Kahala Passage, 30 minutes to buy tickets, a circuitous path to the top of the mountain, and a black tunnel between 200 steps to the top of the mountain behind the first viewing platform. In fact, the top of the mountain was the military fortress of the former US army, and it was quite drifting to climb out of the shooting hole of a blockhouse. Lighting, north of Wangweijiji beach, east of Koko volcano, south of the lighthouse, west of the endless Pacific Ocean, the crater of the volcano like a big pot [snickering].
