The SKYbar on the top floor of the DoubleTree by Hilton Edinburgh City Centre is usually only open to the public on the first Thursday of every month.
However, during the festival it's open every Thursday during August where it will be partnering up with various brands for each event.
The penthouse bar was also recently announced as a venue for the Edinburgh Cocktail Weekend in October, during which ECW wristband wearers can relax with SKYbar’s signature cocktail while taking in spectacular views of Edinburgh Castle and the city’s skyline.
Conference & events manager Annabel Drysdale said: "The SKYbar has a truly iconic view of the Edinburgh skyline and the best view of the castle in the city!
"This hidden gem on the 5th floor of the DoubleTree by Hilton on Bread Street and is normally open the first Thursday of every month, but throughout August we are open every Thursday 6pm – 1am.
"Enjoy cocktails and a special sponsored drink every week, have a bite to eat from the BBQ on the terrace and you’ll see the nightly fireworks from the Tattoo at the Castle.
"Taking in the views gets you away from the hustle and bustle of the festival on the street and lets you relax as you take in the sights of our hyper crazy city."
