Impossible to pass this pool! Danube Arena is an aquatics complex located in Budapest, Hungary. Designed by Marcell Ferenc and completed in 2017, this cool spot features two Olympic-size swimming pools, a diving pool, and a short course training pool. With a seating capacity of 5,000 permanent seats and 8,000 temporary seats, it has hosted various events like the World Aquatics Championships and European Water Polo Championship. It's basically a must-visit for all water sports enthusiasts!

It is open for public and easy to get in! Recommend to try it out because exactly here I was breaking the records at World Cup and spent so many hours training.
