The Adalaj Vav, 19km north of Ahmedabad, is among the finest of the Gujarati step-wells. Built by Queen Rudabai in 1499, it has three entrances leading to a huge platform that rests on 16 pillars, with corners marked by shrines. The octagonal well is five storeys deep and is decorated with exquisite stone carvings; subjects range from eroticism to buttermilk.
From Ahmedabad, an autorickshaw costs ₹450 return, or take bus 85 from Lal Darwaja to Chandkheda, transfer to bus 501 towards Sarkej, and ask the driver to let you off at the Adalaj Vav turnoff, from where you can walk or take an autorickshaw about 1km.
