I Didn't Know That!: Leave No Trace Principle #2 - Travel & Camp on Durable Surfaces

You’ve seen it before. You’re walking along a trail or path, when all of a sudden - BAM - a mud puddle is taking up the entire width of it. What is the most Leave No Trace thing to do?

You might assume that the best course of action would be to walk around the mud puddle. Who wants to get their feet all wet and muddy? But let’s think about what we would be stepping on if we were to do that. The sides of trails are typically lined with all sorts of vegetation. Grass, flowers, moss, ferns - all surfaces that our footsteps could easily damage, especially when we consider all the other hikers who will come after us and may do the same. Perhaps we are in the desert and going around the mud puddle would require us to walk through fragile soil crusts. All of these options could cause a great deal of impact. Luckily, there is an easy and low impact alternative.

Go through the mud puddle.

Did You Know?

Traveling and camping on durable surfaces is one of the 7 Leave No Trace Principles. These Principles empower you to leave nature as unchanged by your presence as possible. It’s a way of protecting the natural world and yourself and to preserve our outdoor spaces for the enjoyment of generations to come.

The most durable surface for us to walk, hike, or bike on is always going to be the trail. That is still true when the trail is muddy. Instead of walking off the trail to go around the mud puddle, it is a more Leave No Trace practice to stay on the trail and walk right through it.

We still likely don’t want to get our feet wet, so this can require us having proper footwear for the activity we are doing. If the trail is really wet and muddy and our steps or bike tires are causing a lot of wear and tear, it might be the most Leave No Trace option to wait a few days for the trail to dry out before we use it.

There are instances when you can get around a mud puddle on durable surfaces - maybe some perfectly placed rocks provide a stepping stone - but we always want to be ready and prepared to go through puddles we encounter on the trail. This helps to protect vegetation, minimize soil compaction, and improve the sustainability of the trail.

What Can You Do

Going through mud puddles rather than around them is one of the least known concepts in Leave No Trace. Teaching the other people you meet outdoors "the why" behind this practice can protect fragile vegetation and soils from being trampled.

Pass It On!

Did you learn something new? Pass it on! Protecting our ecosystems is a job for us all, but there’s no way for everyone to be an expert in everything. That’s why sharing knowledge is so important!
