Visited Devbagh, Tarkarli and Malvan. Stayed at Omkar Deluxe in Devbagh.
Devbagh beach is more like a secluded private beach, with very few visitors around.
Water sports Jet ski, Water scooter, Banana ride etc. at Tarkarli back water is fun.
Best is the Scuba Diving organised near Sindhudurg fort at Malvan. The guides are well trained and helped novices/first timers like us to do Scuba diving. They also took under water Photo, while I was holding the coral reef. It was thrilling to hold the coral reef, while small fishes were swimming all around.
Only draw back is water is not very clear and hence visibility is limited. Request the Scuba diving organisers to develop new Locales, which are less crowded.
Tip to pure vegetarians, stay at Malvan or nearby, as Pure vegetarian food joints are in Malvan only. In Devbagh and Tarkarli all Hotels serve mixed fare, though the quality of Veg preparation is also good. Most of the Bill Boards in this area read "sudh sakhahari, swadist manshahari, translated it means Pure Vegetarian, Tasty Non Vegetarian. This belt is famous for its Malvani Sea Food.

Traveled all the way from Mumbai to get nothing.
A vast expanse of beach with nothing much of interest.
Had gone for snorkeling which was not possible due to unclear water.
wasted 10 hours of travelling one way and then back for nothing

The Konkan coast has a number of beaches... and nice beaches I would say however this recent trip to Tarkarli just swept me...
Ganpatipule used to be on top of my list however Tarkarli has given a big fight... n ya... am a waterbody :) I love water however thats not the only thing I look for while planning a vacation, I also look for the place, the facilities, approach and other to do things around... counting all of that, Tarkali is certainly an Ace.
The place is far from Pune and took us fair amount of time to reach... an advice, dont go via Kolhapur, take the Nipani route which has much better roads... Tarkarli has the beach and a few good resorts/ hotels however the town is Malvan (8 kms) where you get what you get in a town :)
now talking about Tarkarli... I have never seen a beach so calm... at 3 PM, there was not a single wave coming, water had no push or pull... as silent as a pool... weird hmmm!!
n the clarity...wow... shoulder depth water and I could see my shadow on seabed...
no rocks... no stones...no weeds... just blue vastness... ah... heavenly...
MTDC has the best property I would say... beach just in front of cottages and restaurant...
there are other hotels as well and not so costly...
now Malvan... thats the town with okay restaurants, you could find food which is not seafood... ha ha... the beach there is nice too...
now to add to it all... Scuba and Snorkeling... I think its the only scuba site in Konkan... though they dont take you quite deep yet its a fun experience... loved it...
I could brag more about the place... colors... cleanliness...serenity... n tell me assure you... you will get it all...
the CALM I wanted to find...
