On day 2, I went to Devbag and took ferry for Tsunami Island. They cost around 1200-1500 for ferry rides which covers 6-9 points. We took Rs1500 package which covered 9 points. Some of them are Dolphin point, Seagal point, Nivti rock Beach, Golden rock, Tsunami Island, Devbag Sangam, etc.
I will suggest you to take ferry in Morning if you expecting to watch Dolphins. You can get ferry at earliest around 8:30am. The feeling of sitting on the front top of ferry was just Jawdropping.
Although we didn't wore lifejackets but I will advice you to wear because we usually go 30-40km away from the Devbag Beach amid of sea.
Meanwhile, you will witness some of the small island and they will make you feel like 'Zindagi Na Milegi Dobara'. Do ask for halt at seagal island. The view is just spectacular sea water is crystal clear. Best for photography enthusiast.
In the end, We did kayaking at Tsunami Island. It costs around 200 for two peeps. It was amazing experience rowing it.
If you are wondering why It is names as Tsunami Island.. Basically it was formed during tsunami hits and luckily this Island was formed.
