From Calcutta, you can either drive down to Mandarmani or catch a train. Every day, about 4 trains run from Howrah to Digha. The journey being 3 hours, it is a beautiful way to set for a family vacay. That is what we chose for; munching on jhaalmuri, samosa, chop, chips, sipping on hot, and engaged in long and hearty laughable discussion, we reached Digha around 10:00 am. (We were travelling in the Tamralipta Express that departed Howrah station at 6:35 am. Note that to go to Mandarmani, Kanthi or Contai is a better station to get down. But the halt is for a very short time. Do not give it a try if you are carrying a lot of luggage and have elder members of your family travelling with you.)
The driver from our hotel had come to receive us at the Digha station. Ample of autos and tempos are always available outside the station and hence, the area is usually over crowded. In case you are looking for hassle free travel, do ask your hotel to send a cab. The travel time from Digha to Mandarmani is around 1 hour. However, based on the road condition it might take around 1 and a half hour. Cab fare from Digha to Mandarmani is Rs 600. And autos would charge you around Rs 300 for the same.
Mandarmani isn’t usually flocked by a lot of tourists. So, you would usually find it a little secluded. That is one of the main reason why we chose this place for a family getaway. We were put up at the Candlewood Park Beach Resort. The property was a little away from the main bus stop or market of Mandarmani. Needless to say, that this property was the single most reliable solution that I found over the internet.
