Adalaj Vav, 18 kilometres north of Ahmedabad on the road to Gandhinagar, is the most spectacular stepwell in Gujarat. Five storeys deep, the well descends through octagonal landings with carved pillars and brackets on every level. The carvings mix Hindu, Jain, and Islamic motifs — a sign of the syncretic culture of the period — and the temperature at the bottom is reliably 5 °C cooler than ground level, even in summer.
The well takes about 45 minutes to visit. Combine it with a stop at the Akshardham temple in Gandhinagar for a half-day trip from the city.
