The Sabarmati Ashram, on the western bank of the river two kilometres north of the centre, is where Mohandas Gandhi lived from 1917 to 1930. From here he ran his journals, organised the freedom movement, and developed the philosophy of satyagraha. His small whitewashed cottage, Hriday Kunj, is preserved with his spinning wheel and writing desk; an excellent museum next door displays original letters, photographs, and the few possessions he owned at his death.
The site is more atmospheric than its scale would suggest — a quiet riverside complex of low buildings, neem trees, and a meditation hall under a banyan. Entry is free and visits are best in early morning before the tour groups arrive. Plan an hour and a half at minimum.
