A 15-minute walk from the entrance on the way to Tiu Kelep leads you to the first cascade, Sendang Gile. A more challenging 45-minute trek through jungle and streams takes you to the second waterfall, Tiu Kelep. The entire experience takes about two and a half hours. The entrance fee is 20,000 IDR per person.
If you are going early to have Tiu Kelep to yourselves I recommend skipping Sedang Gile at first and visiting it on the way back.
