Beijing Aquariums: Underwater Tunnels & Night Sessions to Beat the Summer Heat
Last updated: Jul 19, 2026
Beijing in late July is peak "sanfu" heat — the stickiest weeks of the year, when sightseeing at noon genuinely hurts. On July 19, 2026, the Beijing Municipal Bureau of Culture and Tourism highlighted four city aquariums as summer escapes, and for once the recommendation fits tourists perfectly: they're indoor, air-conditioned, near other major sights, and one of them opens rare night sessions this month.
The Four Spots
- Beijing Aquarium (北京海洋馆) — The flagship, inside Beijing Zoo in Haidian. Over 1,000 species and nearly 10,000 marine animals across themed zones. This is the one with the limited night sessions: 18:00–22:00 on July 24, 25 and 31, 2026 — a rare chance to walk the tunnels after the daytime crowds leave. Day admission is around CNY 170–175 (official Beijing tourism site); night tickets are sold separately.
- Andover Taipingyang Under Water World (太平洋海底世界) — Under the CCTV Tower, so it pairs naturally with a tower visit. Roughly 8,000 m² with an 80-meter underwater tunnel that wraps 90°–270° around you, plus underwater performance shows (currently a "flower goddess" theme).
- Blue Zoo Beijing (富国海底世界) — Near the Workers' Stadium area, the easiest to combine with a Sanlitun evening. Its 120-meter panoramic tunnel is the longest of the four; 6,000+ creatures including 10+ shark species, plus a touch/interaction zone that works well with kids.
- Yasewangguo Ocean Park (亚瑟王国海洋公园) — The newest-style one: 13 themed areas including a rainforest zone, a "Jellyfish Maze" with light-and-music displays, an underwater theater with mermaid shows, and an ocean-themed restaurant.
Why the Night Sessions Are Worth Planning Around
Summer daytime slots at Beijing Aquarium are packed with school-holiday families. The night sessions (18:00–22:00, July 24/25/31) flip the experience: cooler outside, far fewer people, and the tunnels lit up after dark. Night tickets are sold separately from day admission and are typically cheaper — but they can sell out on these limited dates, so book as soon as your dates are fixed. Note the aquarium sits inside Beijing Zoo: daytime visits usually mean buying a zoo + aquarium combination, while night sessions enter for the aquarium only. Confirm the entry gate and rules on the official account when you book.
How to Book
1. Pick your venue
First-timers: Beijing Aquarium for scale and the night sessions. Short on time near Sanlitun/CBD: Blue Zoo. Pairing with the CCTV Tower: Taipingyang Under Water World.
2. Book ahead via WeChat or Trip.com
Each venue sells through its official WeChat account / mini program, and most also list on Trip.com — the easiest option if you don't read Chinese, with English pages and foreign-card payment.
3. Bring your passport
Real-name ticketing is standard at Beijing attractions — carry the passport used at booking for entry checks.
4. Time it right
Go at opening, after 16:00, or to a night session. Midday weekends in July are the worst slots.
Practical Tips
- Use aquariums as your midday block. A good summer rhythm in Beijing: outdoor sights early morning, aquarium 11:00–15:00, back outside for the evening.
- Weekdays beat weekends by a wide margin in school-holiday season.
- Food inside is average and pricey. Eat before or after; the zoo area and Sanlitun have far better options.
- All four accept mobile payment. Have
