To hang a hammock correctly, use two sturdy trees that are at least 10 feet apart and 15 feet from any other object such as a fire pit or rock outcropping. Make sure to choose trees with thick trunks that won’t be damaged by your weight plus the added force of swinging in the wind. Measure the distance between the trees before attaching your straps to ensure you have enough room for your desired tension level and comfort level when sleeping in it.
