This bathing spot in the middle of the jungle is really really nice! There is now a small restaurant again.
Behind the artificial pool there is a natural pool with a mini-waterfall, which you can also climb up (there are more cascades with mini-pools behind). You MUST go at least to the natural pool, otherwise you will miss the best!
For the lazy, there is a guarded car park (created with German tools) at the top at the beginning of the descent, where you can park for a good €3. Motorcyclists and riders offer to take you down or up. But the cultural landscape above (everything organic) and the jungle are really beautiful, rather park and walk on the outskirts of Polo!
