When we think of exploring nature, we often imagine traveling far from the concrete jungle. But sometimes, the most beautiful and enriching experiences lie hidden within our immediate surroundings.

On 3rd November, the Green City Trail to Sion For t by NaturalisT Foundation took place, proving to be a true hidden gem in Mumbai. Located atop a hill within Pandit Jawaharlal Nehru Garden in the busy, bustling suburb of Sion, this historic place often goes entirely unnoticed by everyday Mumbaikars despite its striking beauty and profound significance.

A Glimpse into Mumbai’s History

Sion Fort holds deep historical importance for the region. It was built during the rule of the British East India Company between 1669 and 1677 under the governorship of Gerald Aungier, standing tall on a conical hillock. At the time, it marked the boundary between British-held Parel island and Portuguese-held Salsette Island.

Over the years, it has silently witnessed the massive, sweeping transformation of Mumbai from a cluster of seven islands into a mega-metropolis. In 1925, it was formally recognized as a Grade I Heritage structure by the Archaeological Survey of India (ASI). Exploring this landmark felt like stepping back in time, surrounded by stories from centuries ago written directly into the weathered stone walls.

Biodiversity Spotted on the Green City Trail to Sion Fort

The path leading up to the fort structure was absolutely bursting with micro-habitats and life. Our naturalists guided the group to show that nature doesn’t stop for concrete. During the Green City Trail to Sion Fort, participants closely observed a variety of urban plant species and fascinating insects, including:

Flora: Massive Baobab trees with their signature thick trunks, delicate touch-me-not plants (Mimosa pudica), and wild yellow sulfur cosmos dancing in the breeze.
Fauna: Common Mormon butterflies fluttering near the canopy, tiny signature spiders weaving intricate webs across the shrubbery, and structured columns of carpenter ants sourcing food.

Stink bugs, Katydids, Leaf hoppers, Wasps, Mites, Beautiful species of spiders

This rich biodiversity, found right in the heart of Sion Fort, serves as a beautiful reminder that resilient ecosystems continue to thrive even within heavily populated urban spaces if left undisturbed.

At the Top: A Moment of Reflection

Reaching the summit, our breath was taken away as we were greeted with a panoramic, scenic view of the central city’s sprawling skyline juxtaposed against the green mangrove patches of Thane Creek.

At the same time, we felt overwhelmed by the raw history this place holds and incredibly surprised at how such a magnificent spot often goes entirely unnoticed. It became a powerful moment of reflection for everyone on the trail—a reminder of how easily we overlook the historical and ecological treasures around us in our everyday, fast-paced lives.

A Spiritual Extension to the Journey

At the thoughtful suggestion of one of our attendees, Mr. Chand Shahpuri, the group happily extended the trail past the garden gates to visit the nearby Gurudwara Shri Dashmesh Darbar. This spontaneous addition brought a deeply peaceful and spiritual dimension to the day’s exploration, making the entire weekend experience even more wholesome, inclusive, and memorable for the community.

More Than Just a Nature Trail

This particular Green City Trail to Sion Fort was unique because it beautifully bridged the gap between urban biodiversity, historical exploration, and a touch of local spiritual culture. It showed us that adventure doesn’t always require long train journeys or expensive flights. Sometimes, true exploration lies hidden within our own city lines, waiting patiently to be discovered. In a fast-paced city like Mumbai, experiences like these remind us to pause, observe, and reconnect with nature, history, and ourselves.
