Hawaii Volcanoes National Park is open 24 hours a day, so your chance to see glowing lava (from near or far) is pretty good when the volcano is actively erupting (it's periodically erupting only at the summit in Halemaumau currently), especially when it's dark.
Where is the best place to see the lava glow?
Undoubtedly, the best place to see nighttime lava glow in Hawaii Volcanoes National Park is at the Keanakako'i Overlook. This area is at the end of the now closed portion of Crater Rim Drive. Seismic activity closed the road and now it's been turned into a pedestrian walkway to the overlook.
