Visitor numbers on Mount Karthala, estimated
No official count of Mount Karthala visitors is published. Until the first QR code registrations come in, Karthala 360 has estimated visitor numbers since 2020 from hikers’ public traces, tourist arrivals in the Comoros and Discovermores’ field experience. These figures will be replaced by measured figures.

Data Pro preview: visitor profile, typical year (≈ 1,700 people)
This is the kind of detail Data Pro will provide. Here, everything is estimated and shown openly as an example; with real registrations, this detail will be reserved for Data Pro subscribers, always as anonymous totals of at least 5 people.

How these figures are estimated
- Public traces: 25 confirmed visits found from 2020 to 2026 (Wikiloc tracks, TripAdvisor reviews, blogs, videos, press), about 1 to 3% of foreign visitors.
- Tourist arrivals: 69,831 air arrivals in 2023/2024, 68% from Europe, 19% from Africa and 13% from other regions; over 80,000 in 2024. We assume 1 to 4% of leisure tourists climb Mount Karthala.
- Field experience: according to Discovermores, the high season is very busy, mostly with young diaspora holidaymakers and schoolchildren. These groups post little on the open web: their share (about two thirds) is the most uncertain.
- Visitor profile: an assumed breakdown (sex, age, nationality, month, with whom) for each of the four groups, weighted by their size. These are assumptions, not measurements.
- Not counted: guides, drivers, scientific and technical staff, herders going up to their camps.
