Begin your adventure at Debrecen Zoo, the second-largest zoological park in Hungary. Home to over 165 different species of animals, including endangered ones like red panda and snow leopard, you can easily spend a couple of hours admiring them all. Don't miss the giant aquarium which offers a glimpse of the underwater world.
For the ultimate water adventure, head to Hajduszoboszlo Aqua Palace, one of the largest indoor waterparks in Europe. With 30 pools, including thermal pools, and over 20 different slides, you'll be spoilt for choice. The kids will love the various water attractions, while adults can relax in the wellness area with massage treatments and saunas.
If you want to take a break from the adrenaline, visit the Bocskai Istvan Museum, one of the oldest public collections in Hungary. The museum showcases the history and culture of Debrecen and its surroundings with numerous archaeological, ethnographic, and fine art exhibitions. The highlight of the museum is the collection of gold and silver objects, including a medieval treasure trove.
End your day exploring the Nagyerdei Park, the largest public park in Debrecen. The park features a variety of recreational activities from cycling to rollerblading in the skate park or rent a boat in the lake. If you still have energy, climb the 57-meter high observation tower to enjoy the panoramic view of the city.
If you have more time, you can check out the Hortobagy National Park, Europe's largest semi-natural grassland that is home to unique flora and fauna. If you have less time, skip the Bocskai Istvan Museum and stick to the outdoor activities for an adrenaline-packed day. Make sure to bring sunscreen, towels, and extra clothes for the waterpark.
