Alibaug, a coastal town in Maharashtra's Raigad district just 100 kilometers south of Mumbai and accessible by a scenic ferry ride from the Gateway of India, is the preferred beach escape for Mumbaikars and is increasingly popular for its luxury beach resorts, water sports, and historic Maratha coastal forts. The Kulaba Fort rising dramatically from the sea near Alibaug beach, the beautiful Kashid Beach, and the forested hillsides of the Konkan coastline make Alibaug a scenic destination beyond its role as a city escape. The region's fresh seafood, particularly the Alibag seafood thali, and the lush Konkan landscape in monsoon make Alibaug particularly enchanting from June to September.

Kolaba Fort is Alibaug's most iconic attraction — a 17th-century Maratha sea fort by Chhatrapati Shivaji on a tidal island just offshore, accessible on foot at low tide or by boat at high tide. Remarkably well-preserved, with ancient cannons, temples, and freshwater wells within its walls. A top Alibaug sightseeing and heritage destination. Free entry; check tide times before visiting. Best explored with a local guide for historical depth. The low-tide walk across the sandy causeway is memorable.

Alibaug Beach is the Konkan coast's most accessible beach from Mumbai — a wide stretch of black sand near the town centre with fine views of Kolaba Fort and the Arabian Sea. The closest good beach to Mumbai (2 hours by ferry), it is the top Alibaug sightseeing destination for Mumbai weekend getaways. Horse riding, water sports, and beachside seafood are available. Free entry; most lively on weekends. Take the ferry from Gateway of India for a more scenic arrival.

Kashid Beach is the Konkan coast's finest white sand beach — a 3 km pristine stretch of unusually pale sand flanked by casuarina trees and rocky headlands, 30 km south of Alibaug. Far cleaner and less crowded than Alibaug Beach, it is a top Alibaug day-trip and Maharashtra beach destination. Free entry; several beach resorts offer overnight stays. The coastal drive along NH66 through the Konkan is itself rewarding. Best visited October–February on weekdays.

Murud-Janjira is India's most unconquerable sea fort — an island fortress off the Murud coast, 50 km from Alibaug, that resisted Marathas, Portuguese, and British fleets across 350 years of naval history. Its towering 19-metre walls and 19 bastions remain largely intact. Accessible only by boat from Rajapuri jetty. A top Alibaug and Konkan coast heritage sightseeing destination. Boat charges apply; best visited October–February. One of Maharashtra's most extraordinary and dramatic historical landmarks.

Kihim Beach is Alibaug's most serene and least-commercialised shore — a narrow, forested stretch lined with coconut palms and casuarina trees, known for its rich birdlife and butterfly population. Popular with Mumbai nature enthusiasts seeking quiet over crowds, Kihim is a top Alibaug eco-sightseeing destination. Free entry; a few heritage bungalow homestays nearby. Calm, shallow waters are safe for children. Best visited October–March on weekdays. A complete contrast to the busier Alibaug town beach.
