The free tour system works differently in Granada because of the cobbled slopes of the Albaicín and the seasonal timetables. You pay nothing upfront — just enter your name and email and your place is confirmed for a walk through the UNESCO World Heritage neighbourhoods with privileged views of the Alhambra.
You receive email confirmation with the exact meeting point (Plaza Bib-Rambla or Plaza de Santa Ana depending on the tour), the departure time and your guide's direct contact details. If you have questions about the slippery cobblestones on rainy days or need recommendations for after the tour, you can contact the team directly before setting off.
Granada's free tours suit any type of traveller but do require comfortable footwear for the Albaicín slopes. The advantage is that you pay the tip you feel is fair after discovering the secret viewpoints with the finest views of the Alhambra and hearing the Nasrid legends that only local guides share.
In peak season, book in advance as the sunset time slots fill up quickly. The walk through Plaza Bib-Rambla, the Cathedral, the Alcaicería and the lower Albaicín gives you the perfect grounding to then decide which monuments to explore from the inside, such as the Alhambra or the Royal Chapel.
