Gujarat's newly inaugurated Tropic of Cancer Science Park at Salal village in Prantij taluka, Sabarkantha district, has welcomed more than 3,500 visitors within its first two months of opening, according to officials. Authorities expect footfall to climb further as the ongoing summer vacation draws students and families to the site.

Background and Development

The park was developed by the Gujarat Council on Science and Technology (GUJCOST) under the state government's Department of Science and Technology, at an estimated cost of ₹8 crore over an area of 5,930 square metres. Chief Minister Bhupendra Patel formally inaugurated the facility on 11 March.

At the inauguration, Patel said that 'such initiatives were important for nurturing scientific temperament among citizens and students.' Officials also noted that Prime Minister Narendra Modi has consistently emphasised the need to promote scientific thinking and build understanding among children about modern science.

What the Park Offers

Designed as a self-explanatory, open-air science laboratory, the park features outdoor exhibits, astronomical structures, and visitor amenities. Through interactive displays and instruments, visitors can observe how the Earth's axial tilt drives seasonal change, how the Sun's movement and shadow patterns shift across the year, and how sundials can be used to measure time and track the Sun's position.

The site also allows visitors to physically stand on a latitude line of global significance — the Tropic of Cancer, which lies at 23.5 degrees north of the Equator. Beyond scientific exhibits, the park incorporates natural surroundings and spaces for cultural programmes. Officials describe it as an interactive educational and research centre aimed at explaining the relationship between the Earth and the Sun.

Geographical Significance of the Tropic of Cancer

The Tropic of Cancer, also known as the northern tropic, is the northernmost latitude at which the Sun can appear directly overhead at noon. The imaginary line passes through 16 countries, three continents, and six water bodies worldwide. Tropical regions, which lie between the Tropic of Cancer and the Tropic of Capricorn, cover approximately 40 per cent of the Earth's land area and are known for rich biodiversity.

In India, the Tropic of Cancer passes through eight states — Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram. Within Gujarat, it traverses seven districts: Aravalli, Sabarkantha, Gandhinagar, Mehsana, Surendranagar, Patan, and Kutch. Officials noted that the line's passage through northern Gujarat contributes to the state's experience of both extreme heat and cold.

Broader Impact and Outlook

The government has positioned the park as a science tourism destination for students, tourists, and science enthusiasts, aiming to transform an abstract geographical concept into a tangible, experiential learning environment. Officials said the project is also expected to generate new local employment and development opportunities in the area. With summer vacation footfall still building, the site's visitor numbers are anticipated to grow considerably in the weeks ahead.
