Graja-Tours owner and guide, Lotte von Lignau (R), talks to hikers as they take part in a tour to visit the Tajogaite volcano, previously known as Cumbre Vieja for the ridge on which it sits, in Los Llanos de Aridane, on the Canary Island of La Palma, on September 12, 2022. - Since the Tajogaite volcano erupted on Sept 19, 2021, spewing rivers of molten rock and ash plumes into the air, interest in visiting La Palma -- one of the less visited of Spain's tourism-dependent Canary Islands off Africa's north-western coast -- is booming.
