On a shared trail, bikers give way to hikers and horses, and everybody gives way to folks with mobility differences. It's the same rule you already follow at a four-way stop: know your place in line, and go.

Think you know Leave No Trace? Take our free online course and find out.

LNT 101 covers the 7 Principles, wildlife basics, waste disposal, and low-impact camping — the stuff that actually keeps trails and campsites in good shape. Most people who take it tell us the same thing: at least one thing they thought they knew turned out to be wrong.

It's free, it's online, and it takes less time than binge-watching this video ten times. Take it here: https://zurl.co/3dAUS

What an incredible few days on the Fjällräven Classic USA! We had the opportunity to connect with hikers from around the world, sharing Leave No Trace education and simple ways we can all protect the places we love. From trail conversations to stewardship, every interaction reminded us that conservation is a global effort. Here's to more adventures and more outdoor stewards!

When a trail's backed up, it's tempting to step around the crowd. That's how braiding starts — multiple parallel paths eating into vegetation that won't grow back this season, or maybe ever. Waiting ten seconds costs you nothing. Widening the trail costs everyone.

Same trail, different day, completely different experience. Hitting popular spots early morning or on a weekday means less crowding, less impact, and, honestly, a better experience. Check visitation data or ask local land managers before you commit to a Saturday afternoon at the most popular overlook in the park.

It's Plastic Free July, and we're here with some tips to keep our coastlines free of plastic! 🏖️

Plastics make up a significant portion of litter both on beaches and in the oceans. This waste not only makes beaches less enjoyable for humans, but hurts marine life. Reduce your plastic usage and Leave No Trace by following our principles.

🚰 Know Before You Go: Start off strong by not bringing any single-use plastics or styrofoam with you. Instead, bring your food and liquids in reusable containers to keep them fresh on your trip!

🗑️ Trash Your Trash: Pack out all your trash with you, plastic or not! Instead of using a new plastic trash bag, consider getting a reusable dry bag, or repurposing another bag you have.

🐕 What To Do With P**p: Bring a reusable or eco-friendly bag for your pet waste, or reuse a handy bag from the grocery store.

🫂Be Considerate of Coastal Communities: We love our coastal communities, so respect them by not leaving plastic litter.

The best way to Leave No Trace is to stop waste at its source! While it can be hard to stop using plastic entirely, eliminating single-use plastics and reusing what you have goes a long way.

Most outdoor spaces don’t stay open simply because they’re public. They stay open because people care for them.

The future of our public lands depends on the choices we make when no one is watching.

Protect the place. Protect the experience. Protect access.

Land managers don't want to close trails, cap permits, or add more rules. They do it when overuse forces their hand. Every person who packs out their trash, stays on the trail, and gives wildlife space is part of why a place stays open instead of getting locked down.

Every time we gather outdoors, we have an opportunity to make a difference.

Through education and strong partnerships, we’re helping people build the skills and confidence to enjoy the outdoors responsibly while protecting the places that make these experiences possible.

The outdoors belongs to all of us, and caring for it is something we can accomplish together. Thanks to everyone who helps make this work possible.
