To minimize disturbance to the environment, you should camp in the backcountry on either a backpacking or dispersed trip. This means that your campsite shower should be at least 200 feet from all water sources. Some recommend going as high as 300 feet. It is not necessary to use soap. Campers and backpackers generally agree that it is unnecessary. To make your shower more pleasant, you can use a camping towel or bandana to apply the soap and then wipe off with a clean cloth. It is important to make sure that no water from your shower reaches another source. However, a soap that biodegrades can help reduce the environmental impact.
