Once you arrive at the gate going to Daranak Falls, pay the entrance fee then walk for a few minutes to reach Daranak falls.
Batlag Falls is just a few meters away from Daranak (there is a separate entrance fee if you opt to visit this waterfall).
There are available cottages that you can rent.
The place gets crowded during weekends, holidays and summer vacation.
You can ask the tricycle driver to wait or just come back for you at the agreed time.
Always observe the LNT principles.
