The name 'Lembah Pelangi' translates to 'Rainbow Valley', derived from the frequent appearance of rainbows in the waterfall mist.
The waterfall is technically part of the Ulubelu geothermal area, known for its active volcanic soil and geothermal features nearby.
The primary descent involves two main levels, with the upper tier feeding directly into the lower pool.
The location is remote, requiring a trek through hilly, forested topography that remains relatively untouched by mass commercial tourism.
Air Terjun Lembah Pelangi is a multi-tiered waterfall located in the Tanggamus Regency of Lampung, Indonesia. The waterfall features two distinct levels of water descent that create a mist-filled basin often producing rainbows when sunlight hits the spray. It is situated within a valley environment characterized by dense tropical vegetation and rugged terrain. The water source originates from the highlands, maintaining consistent flow throughout the year. Visitors must navigate a steep, descending trail from the main entrance to reach the primary waterfall basin. The site is known for its natural, unmanicured landscape rather than highly developed tourist facilities.

Wear high-traction hiking footwear as the descent path can be extremely slippery and steep.
Carry waterproof bags for cameras and electronics due to the heavy mist present at the basin.
Visit with a local guide if you are unfamiliar with the area, as paths are not clearly marked for tourists.
Avoid visiting during or immediately after heavy rainfall, as the trail becomes dangerously muddy and the waterfall flow can trigger flash flooding.
Respect local customs by dressing modestly and carry all trash out of the forest as there are no waste management systems on-site.
