It seems there’s been a mix-up in the initial request. Pelabuhan Gilimanuk Port is not located in India but in Bali, Indonesia. Therefore, the beach description might not exactly match the geographical details you provided. However, I'll go ahead and provide a description based on the typical beach aspects and specified amenities, adapting it to fit a general coastal area which could be imagined as Menamkulam for the purposes of this exercise, but keeping in mind the actual location is in Bali, Indonesia.
