Actually, first, we need to define what we mean by a good cocktail because there are strong cocktails, big cocktails and good cocktails and they don't always come in the same glass.
When it comes to the best-made and most original cocktails on the island, there really is only one place you need to know about.
The Atelier Cocktail Bar in Playa del Inglés
The Atelier Cocktail Bar is without any doubt the leading quality cocktail bar in Gran Canaria. The drinks here are made by mixologists using top quality spirits and locally-sourced ingredients and each one is a balanced marvel.
Set on the eighth-floor terrace of the smart Bohemia Suites & Spa hotel on Avenida Estados Unidos 28, the Atelier has panoramic views of the resort and the Maspalomas dunes.
It opens to the public every day with access to the rooftop via a lift. See the cocktail menu here.
The Atelier isn't cheap (cocktails for around 10 euros each) by Gran Canaria standards but you are paying for the best drinks on the island and a view to die for.
The best south Gran Canaria cocktail is your favourite one
When we asked Gran Canaria fans about their favourite cocktail we got a huge range of answers and not that much consensus (except for the fact that the very best ones are at the Atelier). It appears that there isn't a lot to choose from between the cocktails served at most Gran Canaria bars. They are big, bright and strong and that's what people like when they are on holiday.
Having said that, the drinks at The Tipsy Hammock down on the strip in front of Playa del Inglés beach got a good few thumbs up, especially the fruity daiquiris.
If wine is more your thing than big cocktails, head to Taste Mesón in Arguineguín for 300 wines all served by the glass.
Good cocktails in Las Palmas city
If you're in Las Palmas, the hipster-inspired giant gin and tonic boom is still going strong so you'll get a good choice in most places.
Head to El Tendedero de Catalina for good gin and tonics and well-made mojitos; you also get a great view of Santa Catalina Square from its rooftop terrace on top of the Bed and Chic Hotel.
Or go to the El Mono Malvado in Plaza Farray for a good range of well-made cocktails.
In old town Vegueta, La Azotea de Benito makes them big and bold and has great views of the rooftops from its huge terrace. Try a rum and coke with their cherry bitters!
