Weekends we go to the beach for long, lazy unwinding sessions. Either that, or, when we're more actively-inclined, we rent a kayak, SUP or sail dinghy.
The Manamana beach (private) and Water Venture beach (public) are just down the road for us, so we go there more than Sentosa, which is great too for a day of beach-bumming, albeit a little off the beaten track from where we are. Not to mention a wee bit on the pricey side.
Anyhoo, if you're looking for a place that is blissfully devoid of any kind of leaf-blowing, whipper-snipper, mozzie-fogging, lawn-mowing, hedge-cutting, tree-pruning, construction or traffic noise, you can't really go wrong with the East Coast Park beach.
