My Personal Experience Visiting Jantar Mantar in Delhi

During my visit to Jantar Mantar in Delhi, I went in the late afternoon of February. The crowd was moderate—enough to make the place feel lively, but not overwhelming. If you are planning your trip, you’ll find India Gate just a short distance away, and Janpath Market is also close for some quick shopping. For a relaxed hangout, Connaught Place is a great spot, and it’s only a few minutes from Jantar Mantar.

However, if you are someone who would love photography at Jantar Mantar, I’d recommend visiting in the morning on a weekday. When I went on a weekend afternoon, the place was relatively busy, which made it a little challenging to capture clear shots without people in the frame. The lighting is also softer in the morning, which can help improve your photos of the astronomical instruments and yantras at Jantar Mantar.

So, if you are looking for a quieter experience and better photos, aim for an early visit on a weekday. It’ll give you a chance to explore the historic site without the crowds and capture the perfect shot of its fascinating instruments.
