The Rao Jodha Desert Rock Park was developed in 2006, with the aim of restoring the natural ecology of a large rocky wasteland area next to the Fort. Neglected for many years, it was overrun by an invasive thorny shrub. After the shrub was eradicated, over 80 native species of rock-loving plants from the Thar desert were grown there. The Park extends across 70 hectares (around 200 acres) of rehabilitated land and has a walking trail. It's interesting to explore at different times of the year, as its foliage changes with the seasons.
Location: At the foot of Mehrangarh Fort. Enter from the Visitors' Center, 800 meters from the Fort's main gate.
