💡 Blogger Pro-Tips for Timing

If you want a daytime tan: Arrive by 08:30 AM. Lines form before the 9:00 AM opening, and if you aren't early, all the prime shaded spots under the canopies will be taken. The best overall experience: Skip the scorching midday sun entirely and go for Night Swimming (06:00 PM – 10:00 PM) at Ttukseom or Jamsil. The water is cool, the city lights turn on, you escape the UV rays, and the vibe turns incredibly romantic and relaxing.
