The hike Antigua is famous for: climb through cloud forest to a high camp facing Volcán de Fuego, watch it erupt through the night and, if you are fit and acclimatised, push on to the Acatenango summit for sunrise. Strenuous, cold and unforgettable.
2 days, 1 night$$Book on Viator → The easy volcano: a short guided hike over black lava fields on Pacaya, with views of Fuego and Agua, followed on the tour linked here by lunch and a soak in nearby hot springs. A full day, and far gentler than Acatenango.
9 hours (full day)$Book on Viator → A volcano-ringed highland lake with Maya villages on its shores. A long but rewarding day from Antigua takes you down to Panajachel and across the water by boat to lakeside villages. Start early and expect hours on the road.
About 10 hours$$$Book on Viator → The highlands' great Maya market, with textiles, masks, produce and incense at the steps of Santo Tomás church. The tour linked here adds the Iximché ruins and runs about eleven hours, so confirm market day before you book.
About 11 hours$$Book on Viator → Walk a family coffee farm in the hills near Antigua and follow the bean from plant to cup. The linked tour is rated near perfect by reviewers and runs two to three hours, with a gentler walking option or a 4x4 version.
The best first morning in town: a guide-led small-group stroll through Central Park, the San Francisco church and Casa Santo Domingo, with the earthquake story that explains every ruin. Rated highly, three to four hours, and priced gently.
