Volcano Watching information
Lonely Planet review
For a while, the attraction of watching the erupting Volcán Tungurahua practically dwarfed the town's baths. Although not as dramatic as it was, the volcano still puffs smoke and ash and seeing it is an unforgettable experience. The crater cannot be seen from the town itself. You have to walk either to Runtún, to the northern edge of town, near the Puente San Francisco, or to other spots outside town.
The tourist office provides free maps that pinpoint the best places. Tour companies offer night tours that are totally worthless unless the volcano is more active than it was in 2005 and 2006. Find out first.
