Biodiversity Park (Sector 91)

Spread across roughly 75 acres in Sector 91, along the Noida–Greater Noida Expressway corridor, the Biodiversity Park is the largest green lung the city has and one of the more quietly ambitious rewilding stories in the National Capital Region.

• What is today a canopy of native neem, jamun, banyan, peepal and mango began as a monotonous plantation of thirsty eucalyptus; the Noida Authority reimagined the site as an urban forest planted almost entirely with indigenous species, threaded by two lakes, an amphitheatre and several kilometres of looping cycle and walking tracks.
• The result is the closest Noida gets to a genuine forest bath within its own postal code.
• Come early and the park belongs to walkers, joggers and cyclists tracing the paved loops beneath the trees.
• Peacocks call from the undergrowth, parakeets streak green between the branches, and the two water bodies pull in butterflies, dragonflies and a rotating cast of resident and migratory birds — the sort of small, unglamorous biodiversity that a monoculture never supports.
• Grass lawns, bamboo stands and shaded benches make it as much a place to sit as to move, and the amphitheatre occasionally hosts community events.
• It is worth being clear about what this is not.
• Despite the shared 'green' billing, the Sector 91 park is a different animal from the Botanic Garden of the Indian Republic in Sector 38 — a formal, curated botanical institution.
• The Biodiversity Park is a working neighbourhood forest: free, informal and built for daily use rather than labelled specimen-viewing, which is precisely its charm.
• Families spread out on the lawns at weekends, cyclists log laps on weekday mornings, and the mood is unhurried suburban rather than touristic.
• Vegetarian visitors will find the park itself food-free by design, so plan to eat before or after.
• This is comfortable territory: pure-vegetarian dining is easy across Noida.
• The dependable names — Sagar Ratna for South Indian tiffin and Bikanervala for chaat, thali and mithai — sit around Sector 18, roughly nine kilometres north, an easy cab hop.
• Carry your own water and a few fruits or snacks for the walk; there are no full-service restaurants at the gate, and packing in keeps you fuelled without wandering into the area's many mixed non-vegetarian eateries.
• Time your visit to the season.
• October to March is glorious — cool mornings, active birdlife and soft light through the canopy — but do check Delhi-NCR's air quality between November and January, when the regional smog can turn even a leafy park hazy; an N95 mask on the worst days is sensible.
• Summer afternoons are punishing, so aim for the first hours after opening or the cooler evening.
• Entry is generally free, the paved tracks are largely pram- and wheelchair-friendly, and an hour or two is plenty to unwind.
