I took my kids to Haichang this weekend. The weather was cool and not crowded. We entered the park at 9:00 AM and left at 4:30 PM. We saw performances by killer whales, sea lions, beluga whales, and dolphins, went rafting and bungee jumping (Pelican Adventure), visited the seals, the Antarctic penguin pavilion, the Arctic pavilion, the underwater tunnel, Dinosaur Hill, and the Dragon Palace. It was a fun and fulfilling day.
