KOLABAFORT:
it is located 1 km across from Alibag beach. The Great Maratha-warrior Shivaji started the construction of this sea fort in 1680 A.D. The fort is 900 ft. long, 350 ft. wide and has 25 ft. high walls which have 17 bastions (burj) on all sides. The fort has been standing for over 300 years. The fort can only be accessed during ebb tide through a narrow strip of land which goes underwater during high tide. The huge front entrance arch has tigers, peacocks, elephants sculpted on it. Beyond that comes another small gate. Next to that gate are the shrines of Mahishasura and Padmavathi, Kanifnath, Sri Ganesh and the fort-deity. Next to them comes the sourthern gate which is variously known as Darya/Yeshwant Darwaja. Raghoji Angre built a beautiful temple of Shri Ganesh in front of the sweet water tank in 1759. The inner sanctum sanctorum includes images of Sri Ashtabhuja Devi, Shiv, Vishnu, Surya. The collection of the pantheon lends it the name 'Shri Ganesh Panchayatan'. Within the premises, you will find a well and a tank of sweet water in the midst of sea! On one of the 17 bastions, two cannons in intact condition can be seen. The Archaeological Survey of India charges a token entry Fee for the visitors.

VARSOLI BEACH:
It is situated just on the outskirts of Alibag. It is relatively less visited site and as a result is a quiet beach with sparkling white sand and cleaner seawater. Varsoli is a small satellite village across Alibag, complete with thick vegetation of coconut and Casuarina.

REVDANDAPORT:
This historic Port is the last destination in Alibag Taluka, situated 17 kms from Alibag. The creek, which meets the Arabian sea, separates Alibag and Murud Talukas. The creek is busy with sand and fish carrying vessels. To the right across the creek, is Vikram Ispat jetty for unloading the iron ore and to the left is the Ispat factory.

REVDANDA AAGARKOT:
Revdanda is 17 kms to the south of Alibag where remnants of huge outer walls of this fort, built by the Portugese in 1558, can be seen. The thick outer walls are hollow from within and these clandestine routes are interconnected. A structure, in dilapidated state today, known as 'Saat Khani Buruj (bastion) was constructed in 1534. These walls run 5-6 kms in length.

KHANDERI:
Three to four kilometers into the sea from Thai beach, which is 5 kms from Alibag, this fort was built in 1678 on a small island. Later, a light house was erected. This fort was for long under the Angre's control. Today it is under Bombay port trust administration. With their permission, you can visit the fort in local boats.

UNDERI:
Just 374th of a Kilometer away from Khanderi, this is another island fort built by Siddi Qasam in 1680. Supremacy over this fort kept shifting between the Siddis, Peshwas, Angres and later the British. One can visit this fort with permission from the Bombay port trust. Local fishing boats can be hired for a visit.
