Comprising the neighborhoods of Dharavi, Matunga, Vadala, Sion, and Mahim, the northern boundary of this district is where the city ends and the suburbs start. But this distinction has been steadily blurring since 1945 when the city and suburbs were merged into an entity called "Greater Bombay" (The official preferred term is Brihanmumbai, which means the same thing.) The only remnant of this distinction is the fact that autorickshaws cannot enter the "city" limits.

This is a solidly middle-class district, which developed due to immigration after independence (in 1947). The Sindhis and Punjabis were refugees from the partition. They settled in Sion and parts of Matunga. Another prominent community to settle here were the South Indians, especially Tamils. They settled in Matunga and Vadala areas. The poorer migrants from Tamil Nadu settled in Dharavi, which was essentially a drained out swamp. So Dharavi turned into Asia's largest slum.

The district is not a tourist haunt, but if you want a slice of Chennai in the city, you could visit King's Circle, Matunga and explore some of the bylanes. This is one rare district where the roads are actually walkable, as the footpaths in the Sion Circle and King's Circle area are well-maintained and free of hawkers and other encroachments.

Get in

This district is very well-connected with the rest of Mumbai. All three of Mumbai's local railway lines pass through this area. The Central railway stations are Sion and Matunga. The Western railway stations are Matunga Road (not to be confused with the Matunga station on the Central line) and Mahim. The Harbour line stations of Vadala, Guru Tegh Bahadur Nagar and Chunna Bhatti also lie in this region. In addition, the Western-Harbour link runs through this region and there has a stop at King's Circle.

The Eastern express highway runs as far as Sion and runs into a perennial traffic jam at one point. Then it changes over to the Dr. Ambedkar road that runs all the way to South Mumbai. Road connectivity with the Central line is not that good. The roads exist, but are very crowded. BEST buses in the series 1-199 that serve South Mumbai also serve this area and are very frequent.

Mahim

• 1 Astika Samaj Ram Temple (Matunga Khocu Guruyauor Temple, Astika Samaj Kochu Guruvayoorappan Temple), Bhandarkar Marg, (Matunga Stn.). 
• 2 Don Bosco Church and School, Nathalal Parekh Marg ? Matunga East, Mumbai 19 (Kings Circle Station). A very special and tranquil church. This is probably the most prominent landmark in this area. 
• 3 Mahim Fort remains (Marathi: माहीम किल्ला), Mahim Causeway (from Mahim Junction Stn. 0.7 km west). Strategically located in the Mahim Bay, the fort overlooks Worli to the south, Bandra to the north, and Mahim to the east. The origins of the fort are unclear, but it occupies a strategic location that has been frequently contested. The fort is in disrepair, suffering from administrative neglect, encroachment of slums, and exposure to tidal erosion. Large boulders are strewn on the sand and crevices as high as 3 metres (15 feet) are visible. 
• 4 St. Michael Church, Mori Road, Mahim (from Mahim Junction Stn. 0.5 km west), ☏ +91 22 2445 4483.

Sion

• Jesuit chapel (Near to Sion railway station). In 1543, the Portuguese took possession of the islands of Bombay by force, naming it Sião. The Portuguese gave the Jesuit priests the sole ownership of some of these islands. The Jesuits then built a chapel on the hill near the present-day and named it after Mount Zion (Sion) in Jerusalem. 
• 7 Sion Hillock Fort (Sion Killa), Sion East, Air Force Quarters, Sion (Jawaharlal Nehru Garden (Pandit Jawaharlal Nehru Udyan) - Sion Stn. 300 m). It was built by the British Governor of Bombay Gerard Aungier atop a conical hillock. The hillock is a few metres from the Sion railway station. Sion was the boundary between British-held Parel island and Portuguese held Salsette Island and the castle marked the northeast boundary of their possession. The fort was built between 1669 and 1677. The fort is dilapidated and a collection of broken stone steps, scattered walls and ruins, overrun by trees and ground cover. The fort wall has a small room on top. A series of pathways lead to it. The fort offers a panoramic view, overlooking the salt pans in the Thane Creek. However vandalism and apathy have taken toll on the structure.
