Bayinbuluke is definitely worth a visit. Besides swans, we also saw Siberian red-billed gulls at the Swan Sanctuary, and the interaction between the lambs and swans was particularly interesting. It's really cold up there, so be sure to dress warmly!
The scenic area is much larger than I expected. From the entrance to the main attractions, even with no stops and a speed limit of 60 km/h, it takes about an hour, so be sure to allow plenty of time.
The weather was exceptionally good the second time, and I wanted to go back in to watch the sunset. However, when I arrived at the scenic area at 6:30 PM, the staff said the sightseeing bus had already stopped running, so I unfortunately missed it. 🥲 If you want to see the sunset, be sure to check the last sightseeing bus time in advance. Also, if you're driving, after watching the sunset, drive slowly and carefully as it gets dark.
