When to Visit

The optimal time to visit Mount Karthala is during the dry season from May to October, when rainfall is minimal and trail conditions are most favorable for hiking. Temperatures are more comfortable during these months, with less humidity and clearer skies providing better visibility for crater views and photography. The wet season (November to April) brings heavy rainfall, muddy trails, and increased cloud cover that can obscure mountain views, though this period offers lush vegetation and fewer crowds. Always check current volcanic activity levels before planning your visit, as access may be restricted during periods of increased volcanic activity.
