A stay here isn’t quite complete without a visit to Chill Cove at Treasure Bay Bintan, home to Southeast Asia’s biggest manmade seawater lagoon. Just a stone’s throw away, the lifestyle zone offers activities for both sea lovers and landlubbers—from wakeboarding and glass-bottom kayaking to jungle ATV sessions. Not an adrenaline junkie? Consider hanging out with the photo-worthy floats or enjoy a water slide or two. Those keen to explore beyond the resort can take a day trip to Gurun Pasir Busung, a once-abandoned mining site that now has white sandhills overlooking a blue lake. Foodies ought to make a beeline for Rimba Jaya, one of the best hangout spots in Tanjung Pinang after the sun sets.
