The route is very simple, however we made the mistake of trying to follow the GPS route shown by Google Maps, and that was our undoing.
We ended up inside a very crowded part of Delhi with a tiny motorable road hemmed in by small shops and closely packed single-room homes, with water buckets, wares, furniture and children spilling over into the path of our car. Hence I thought I should make it easier for you.
I am taking out the crazy up and down, zig-zag, and u-turning we did for 45 minutes while following the GPS directions.
How to reach Aravalli Biodiversity Park, Vasant Vihar:
We approached the Aravalli Biodiversity Park from the Ring Road. First we took a turn at Bhikaji Cama Place towards Safdarjung Enclave/DLTA Courts/IIT. We went down that road till we reached the T-point under the flyover. There we took a right to get on to the Outer Ring Road.
We left the first left and looked for the main road into Vasant Vihar that leads straight to Modern School along the Poorvi Marg.
You will pass this marketplace on your left just before the turning.
