We did the 5 days and 4 nights trekking in September and is was amazing. Sometimes it was really heavy with hiking up, but the guides were always helpful to the group.
The food was amazing!! Breakfast, lunch and dinner were always different.
Specially the guacamole was amazing! The 4th day we also did the ziplining and I would like to recommend everybody to do this. 1km long zip line with the ground 312m underneath you.
When it's raining the hike can be a bit dangerous so take care you have good shoes and take sticks with you. The mussel pain at the end is al worth it!!.
