Over the past few years I've been taking advantage of prolonged transits in airports to visit a zoo or aquarium. Does anyone else do this? A quick online search reveals that a lot of people enquire about these journeys but I'm unsure about how many people follow them through. It's sometimes a risky game, but often much easier than expected. A few features are required/preferable for this to be a success: Easy & rapid exit and re-entry to the transit zone Straightforward transportation to the desired collection Most importantly; reliable transport and good time management. Easy airports where I've attempted this include Zurich, Switzerland - Zoo: train from airport to main station and tram to the zoo - Voliere: train from airport to main station and a walk/tram ride to voliere Istanbul Ataturk, Turkey - Turkuazoo: metro from the airport to Kocatepe station. - Akvaryum Istanbul (located near the airport complex) - a quick taxi ride, though traffic can be fairly bad. Brussels National airport, Belgium - Brussels aquarium: train ride from the airport to Centraal station, metro from there to Simonis and then a walk through the park. - Antwerp Zoo/Aquatopia: train from the airport to Antwerp Centraal station; the zoo is adjacent and Aquatopia is across the square. Discount vouchers available from the information desk in the station (or for other zoos from the foyer in Aquatopia). Frankfurt, Germany - a failed attempt due to numerous train cancellations on the day of my travel. Airports where I've travelled directly to/from a zoo which seem like potential transit destinations: Copenhagen, Denmark - Den Bla Planet aquarium: a 15-minute walk from the airport. The airport's information desk provide a discount voucher. (Trips to Tivoli Gardens and Copenhagen Zoo or Malmo Aquarium/Reptile Centre [Sweden] also seem feasible) Chiang Mai, Thailand - Taxi from the airport to the zoo/night safari (both are roughly 3 miles away) Changi International Airport, Singapore I don't envy those who have to choose between which collection to visit rapidly in Singapore. Sentosa is probably a less efficient choice. Also worth seeing is the Butterfly garden within the airport (open 24h) - Jurong Bird Park: metro and then bus to the Bird Park Malaga, Spain - Aula del mar: drive/taxi from the city centre to the airport. I believe buses would need a connection. Other nearby collections might be a better use of time (e.g. transfer to/from Benalmadena or Fuengirola) Others which look feasible include Athens International airport, Greece - Attica zoo nearby Tenerife North airport, Spain - Loro Parque a bus ride away (and then a walk, or a quick ride on the zoo train) Banjul International Airport, Gambia - Eagle Heights Gambia nearby Sharjah International Airport, UAE - Arabia's Wildlife Centre nearby For these I have no idea how easy it is to get in/out of the airport so I wouldn't advise these without further knowledge. I'm not sure about US airports - I've not had long enough stopovers with enough freedom to explore apart from Charlotte, NC, where zoo visits were not an option. I'll add others as I recall them. Does anyone else have other experiences of airport transit visits?
