When Delhi feels a bit choking or when you just need a green break the Lodi park seems to like the perfect place to escape to. It's a big green park, which hosts the tombs of the old Sayyad and Lodi rulers of Delhi. It's got some great spots to just sit and soak in the greenery. At least on the day I was there you could even find a tranquil spot for yourself as well. The tombs date back to around the 15th century and sport some beautiful Arabic inscriptions in addition to their imposing architecture.
