The actual meeting point is the steakhouse on the other side of the traffic circle (named CHILOGRAMMO FOOD&DRINKS). The actual tour time was from 9:00 AM to 1:50 PM, which is shorter than the scheduled time. Other than that, everything was very satisfactory. The tour guide was very enthusiastic and talkative, proactively offered to take photos, and was able to look after guests speaking different languages. The volcanic cave experience was very interesting (the guide provides the equipment). The hiking difficulty is low, but the volcanic rocks can be a bit tricky to walk on, so just watch your step.
