A tourist captured a rare full-circle rainbow at Lushan Waterfall Scenic Area, Jiangxi—a complete optical phenomenon rarely visible from ground level.

Social Context

Full-circle rainbows occur only when light refracts through uniform droplets at precise angles—common at high-altitude waterfalls like Lushan. The scenic area’s 2023 ‘Phenomenon Observation Protocol’ trains staff to guide visitors to optimal vantage points during post-rain conditions.

Safety Tip

Photographers should avoid cliff edges during misty conditions, use tripod anchors on wet rock, and check weather radar for sudden downbursts that disrupt optical conditions.
