A fantastic experience during New Year’s Eve. The guide was very welcoming and helped us to the best of his English.
Not related to the tour but it should be noted that we saw many people who couldn’t finish the hike to the crater — It’s a *very* steep hike, hence if you smoke, have not exercised long ago, or have respiratory issues, this may not be for you.
There doesn’t seem to have any regulation on how many people can go or safety mechanisms along the way - Weekdays are best
