3J Sen Sok is the quintessential local hangout, offering a budget-friendly escape that swaps resort polish for authentic neighborhood energy. Come on a weekday and you may find the pool quiet; come on a weekend or holiday and you'll find it packed with kids sporting bright orange life vests and enthusiastic cannonballers.

There is a shallow end for toddlers and non-swimmers, and a few small slides for fun. Floatation devices are available for rent.

You'll find parents floating around in the 1.5-meter deep end, or keeping an eye on their kids from one of the poolside shelters. Food can be brought in, or purchased from one of the food stalls, which serve up cheap Laotian snacks.
