According to the Cambridge Dictionary, a nature reserve is "an area of land that is protected in order to keep safe the animals and plants that live there, often because they are rare". Also known as national parks, they're established to make sure that the next generations are going to see the incredible diversity of plants and animals inhabiting our planet.

There are numerous nature reserves and national parks all over the world. Some of them aim to protect certain species of wildlife inhabiting the area, while others mainly preserve the vegetation. But many parks protect both. To ensure the preservation of biodiversity, a lot of national parks are given the UNESCO World Heritage Status.

Naturally, almost any nature reserve in the world can show something interesting to its visitors. The landscapes of some of them have unique features that can't be found anywhere else in the world. For example, only the Göreme National Park has chimney rock formations, giant tortoises can hardly be seen anywhere else but the Galapagos National Park, and sunset observed in the Namib-Naukluft National Park has no equals.

By visiting nature reserves, you can see how magnificent our planet is. You'll see breathtaking views, hike in the mountains, explore the rainforests, and gaze at the pristine lakes and rivers. The hardest thing about visiting national parks is to choose which ones you should visit first, because there're so many of them out there in the world. So we're here to help you and give you the list of 25 nature reserves that you should certainly visit at least once in your lifetime. Be sure to add them to your Bucket List!
