Located on Perhentian Kecil (Small Island), Long Beach is highly regarded as the center point of activities during the day as well as at night.
It is a long crescent-shaped beach with crystal clear water, excellent for snorkeling, swimming and sunbathing. There are plenty of resorts, from basic to high-end ones, flanking by the beachside.
This highly-reputable beach was supposed to be one of the best beaches in Perhentian, but much to my disappointment, the weather was not cooperating during the time I was there (indeed, 3 days of overcast sky and light drizzles weren't really the kind of weather you will expect during the peak season).
Nonetheless, even without the help of the sun, I could gauge that the water is indeed clear, and the sands are powdery soft.
The house-reef on the left-most side of the beach is a good leisure snorkeling spot. Most parts of the beach has no corals, making it an excellent spot for swimming.
At sun down, the life becomes abuzz with night activities and events, with Bubu Long Beach Resort hosting hula and fire dance at the beach pub.
