This public housing estate with the colorful rainbow facade has become a huge Instagram destination, but please remember actual families live here. The basketball court on the roof gets packed with photographers, especially at sunset. Best time to visit is weekday mornings around 9-10am when it's quieter. Take MTR Kwun Tong Line to Choi Hung Station Exit C3, then follow the signs. The view is free and genuinely striking against Hong Kong's grey skyline. Just be respectful of residents and don't block walkways or make noise in the stairwells. The colors look best in natural light anyway.
