It's included in the Arsenal National Park entrance fee and is far less visited. You can see quite a bit of wildlife. The approach via the unpaved road from Arsenal should definitely be avoided with a 2WD, and in my opinion, with a 4WD.

This green lake contrasts with the rest of the park because it is surrounded by slightly less dense vegetation and a little higher up there are meadows with humped cows.

We had to pay the 12 USD per person at the waterfall lodge and didn't even get to the crater lake. We were intercepted beforehand by the rangers who sent us back. They told us again that it was illegal for the lodge to charge entry into this area, that the trail was not their property. Call the tourist police. The lodge is getting richer and it is also a thorn in the side of the rangers and the tourist police.

Bring enough water to the hike taking into account the way back, as the path can be exhausting and it takes longer than 1.5-2 hours (which is what the locals told us).
