Start your day in Alibaug, where you can experience an adrenaline rush by trying your hand at some water sports such as jet-skiing, parasailing, and banana boat rides. If you prefer to stay dry, head out for a trek to the historic Kolaba Fort. This sea fort dates back to the 17th century and offers stunning views of the sea and Alibaug beach. Continue your adventure by taking an ATV ride on the beach or a scenic horse ride along the coastline.
Mahabaleshwar is a trekker's paradise, and there are many trails that you can explore. Start early morning and take on the challenge of Pratapgad Fort trek. This trek leads you to the top of a hill where the fort is located, and you can witness stunning views of the Western Ghats. If you don't want to climb, then Mahabaleshwar has several beautiful viewpoints such as Elphinstone Point, Arthur's Seat, and Castle Rock. In the evening, relax and enjoy the sunset at Venna Lake.
Your final day can be spent exploring the natural wonders of Lonavala. Visit the Karla Caves and Bedse Caves, which are famous for their ancient Buddhist rock-cut temples. Trek up to the Rajmachi Fort and enjoy the panoramic views. Or, if you're seeking a more adrenaline-pumping adventure, try waterfall rappelling at the Bhivpuri Waterfall. End your day with a drive to Tiger Point, where you can witness the sunset while enjoying a cup of chai.
If you have an extra day, spend it exploring more of Mahabaleshwar, where you can visit its famous strawberry farms or do some wine-tasting at the Sula Vineyards. For a shorter trip, consider skipping Lonavala and simply adding another day in Mahabaleshwar to explore its quaint hill station.
