Browny's Pool is listed as a swimming facility in Grafton, Auckland. It has a 4.6 rating on Google.
A good swimming facility is clean, well supervised and clear about its rules, with water that is comfortably warm and properly treated. Before you go, check whether it is a public pool or a private one, what the opening hours are and whether there are separate times for lane swimming, lessons and play. Regulars know that early mornings and weekday afternoons are quietest, that school holidays and hot weekends bring crowds and that bringing a towel, a hat and a water bottle makes the day easier. Take a shower before you swim, keep young children within arm's reach and follow lifeguard instructions. Jandals help on hot concrete, and it is wise to put valuables in a locker or leave them at home. If you are swimming for fitness, ask about lane etiquette and what speed lanes are set for.
For anyone in Grafton and central Auckland, Browny's Pool is a local place to swim, and worth checking for opening times before you go.
