Air Terjun Tumpak Sewu, Lumajang (East Java)

#tesaruonbudget Often called the "Niagara of Indonesia," Tumpak Sewu stuns with its horseshoe-shaped waterfall plunging into a jungle basin. Entry costs around IDR20,000 (~$1.25), and the main viewpoint is easily accessible. For those more adventurous, hiking down to the base takes effort — but the reward is spectacular. Prepare for slippery rocks, river crossings, and awe-inspiring views. It's truly one of Indonesia’s most incredible natural wonders and surprisingly cheap to experience. For raw beauty and epic Instagram shots, this is #tesaruonbudget perfection.
