• Book the Alcázar tower ahead: tickets that include the Torre de Juan II often sell out on weekends and holidays, and the climb is a narrow 152-step spiral staircase
• Free family gymkhanas from the city tourism office: a treasure hunt across the city, one along the walls, and Real Casa de Moneda hunts for under-8s and over-8s
• Under-16s need an adult inside the Alcázar, and the palace and museum take about 40 to 45 minutes on your own

Segovia's Roman aqueduct strides through the city center on stacked granite arches, and kids can stand right beneath them in Plaza del Azoguejo. At the far end of the old town, the Alcázar is a turreted castle on a rock above two rivers, with suits of armor inside and a 152-step spiral climb up the Torre de Juan II. The city tourism office also runs free treasure-hunt gymkhanas for families.
