Which is the nearest beach? How far are Serenity and Paradise beaches from the hotel?
Nearest sea shore is 1.5 km away but this is a rocky shore with a beach road and walkway that is good for evening walks. Serenity beach was 4.5 km away. I rented a Honda Activa and drove there - 10-15 mins drive. It is OK beach - not very clean and does not have anything in terms of amenities - so don't expect much. For Paradise beach, go ~8km by road to Chunnambar Boat House, from where you take a 20 minute boat ride across chunnambar river to paradise beach (I think Rs200 per head). Paradise beach is definitely cleaner but again better to have low expectations.
Nearest is Promenade/Rock/Pondi Beach (all 3 are same). It's hardly 5 mins distance from a bike or a car. And it's one of the best beaches. But you cannot get inside water as it's covered with rocks at the front.
Best time to visit is in evening or night when they close the road for any vehicles, and only pedestrians can use it. There is lot of parkings available before the beach road starts.
Paradise beach is approx 12-14 kms from this hotel.
