Lava is best seen at night along the south rim. There are three main viewing locations: Kupina?i Pali (Waldron Ledge) from Crater Rim Trail, Kilauea Overlook, and Keanakako?i Crater. Keanakako?i Crater is the closest eruption viewpoint - here you'll see a lava lake that emits a reddish-orange glow at night!
