Responsible Tourism

Leave No Trace: Traveling Responsibly This Summer

Summer travelers need to plan around mandatory permits (Zion's Angels Landing day-before lottery, Rocky Mountain National Park's timed entry from May 22-Oct 12, and Elkmont's 120-vehicle firefly lottery in the Smokies), pick the right swimming hole on Arkansas's Buffalo National River, pack mineral sunscreen, and spend tourism dollars at local businesses that depend on the ten-week peak season.

Traveling Light, Traveling Right, This Summer

Every year the same eight or nine weeks between Memorial Day and Labor Day take the hardest hit on American public land. Parking lots fill by 7 a.m., river gravel bars turn into tailgate parties, and rangers spend more time directing traffic than talking about wildlife. None of that is a reason to stay home. It is a reason to plan around a few specifics instead of relying on good intentions and a full water bottle.


Permits First, Trail Second

Angels Landing in Zion has needed a permit to hike, every day, year round, since 2022, and it still catches people off guard in July. The day-before lottery opens on recreation.gov each morning for the following day's hike, costs $3 per person if you win, and closes fast. Go earlier than you think you should; between May and September the sandstone holds heat well into the evening, and July through September is monsoon season, when a clear morning can turn into a flash flood warning by 2 p.m. Rocky Mountain National Park runs its own version of crowd control: a timed-entry permit is required daily from 9 a.m. to 2 p.m., May 22 through October 12 this year, for most of the park, with a separate Bear Lake Road permit covering 5 a.m. to 6 p.m. through October 18. Miss the window and you wait outside the gate with everyone else who didn't check.


What's in the Water Matters as Much as Who's In It

On the Buffalo National River in Arkansas, not every swimming hole is created equal, and that's worth knowing before you commit to a parking spot. Steel Creek, below Roark Bluff, stays cold even in August because of the spring feeding it. Ponca's low-water bridge is the one everyone photographs, which also makes it the one that gets crowded by 11 a.m. Grinder's Ferry, off Highway 65, is quieter and doubles as a gravel-bar campsite if you're willing to drive in. What you put on your skin before any of these matters more than most travelers realize: Hawaii banned the sale of sunscreens containing oxybenzone and octinoxate back in 2021, and Maui and Hawaii County now require mineral formulas only, zinc oxide or titanium dioxide. That's Hawaii law, not Arkansas law, but the chemistry doesn't stop working differently at a state line, and packing a mineral sunscreen for any freshwater swim is a five-second decision with a real payoff downstream. Best local stop: Pruitt, near its ranger station, has actual restrooms and a water spigot, a small thing that matters after the third gravel bar with none.


Small Towns Run on These Ten Weeks

Scenic byway studies have found that a well-developed route through a small region can pull in a quarter-million to nearly half a million dollars per mile annually in visitor spending, and almost none of that arrives evenly. It lands hard in June, July, and August and thins out fast after Labor Day. A diner, a hardware store that also rents kayaks, a farmers market that only exists because of the season, these businesses are not padding for the trip. They're often the reason locals can afford to live somewhere the rest of us just visit. Buying a $4 peach at a roadside stand instead of at the chain grocery two towns over isn't charity. It's closer to just paying the actual cost of being there.


Some Crowds Are Already Being Managed, Just Not by You

The synchronous firefly display at Elkmont, inside Great Smoky Mountains National Park, is a useful model for what happens when a park stops pretending unlimited access works. The park issues only 120 vehicle reservations per night through a $1 recreation.gov lottery during the peak window, this year predicted for late May into early June, instead of letting cars line the access road until nothing moves. It is a small, deliberate cap, and it works better than the alternative. The same logic applies wherever you're headed for a Fourth of July show or a weekend festival: carpool if there's any way to, carry your trash out if the bins are already overflowing by noon, and treat a local burn ban as the serious warning it is, especially in a dry summer. The parks and towns absorbing all of this traffic didn't ask for it to triple in ten weeks. We're the ones showing up.


None of this requires giving anything up. A permit checked the night before, a mineral sunscreen in the glovebox, a few extra dollars spent at the family-run place instead of the chain, that's the whole ask. Leave a place in better shape than the map suggested you would, and it's still there, unglamorous logistics and all, for whoever shows up after you.

Frequently asked questions

Do you need a permit to hike Angels Landing in Zion National Park?
Yes. Angels Landing has required a permit every day, year round, since 2022. A day-before lottery opens on recreation.gov each morning for the following day's hike and costs $3 per person if you win.
When is a timed-entry permit required for Rocky Mountain National Park?
A timed-entry permit is required daily from 9 a.m. to 2 p.m., May 22 through October 12, for most of the park this year, with a separate Bear Lake Road permit covering 5 a.m. to 6 p.m. through October 18.
Which Buffalo National River swimming hole stays coldest in August?
Steel Creek, below Roark Bluff, stays cold even in August because of the spring feeding it. Ponca's low-water bridge is more popular and crowds up by 11 a.m., while Grinder's Ferry off Highway 65 is quieter and doubles as a gravel-bar campsite.
Why does mineral sunscreen matter for a freshwater swim if you're not in Hawaii?
Hawaii banned the sale of sunscreens containing oxybenzone and octinoxate in 2021, and Maui and Hawaii County require mineral-only formulas (zinc oxide or titanium dioxide). That's Hawaii law, but the article notes the chemistry works the same everywhere, so packing mineral sunscreen for any freshwater swim is a simple precaution.
How do you get into the Elkmont synchronous firefly viewing in the Great Smoky Mountains?
The park issues only 120 vehicle reservations per night through a $1 recreation.gov lottery during the peak viewing window, predicted for late May into early June this year, rather than allowing unlimited cars on the access road.
