The Buddha's Travels

If we look at the map of Ancient India (here) with the locations of the places visited. Then it seems that the town called Thūṇa is further away than Mathura.

Other than that, in the Dhaniyasutta the verse attributed to the Buddha says:

by Mahī’s banks I bide this night alone

The Mahi river is quite far southwest. :point_down:
