The country with the most forests in the world is Russia. This isn’t unusual since this is the largest country and every country has a lot of forests anyways. Also, Brazil has a lot of forests where you can travel through because these forests are rainforests and they are part of the Amazon Rainforest which is one of the biggest rainforests in the world.
Anyone can travel through there, but you should be careful. There are a lot of different animals that live in this forest. They could be dangerous. Also, if you don’t know where you are going, you should get a tour guide. Russia may be limited in regards to the forests that they have available to see based on the climate there.
