The Annual Migration of Flip-Flops
A hundred and fifty years of falling for this valley, a man who never should have worn those shoes on a trail, and a reminder to give the new mothers their room

BEFORE THE COFFEE GETS COLD Moe was up at Bear Lake Trailhead before sunrise, headed for Dream Lake the way he does most weeks once the snow clears off. Said he passed a fella on the trail in flip-flops, moving steady toward Bear Lake itself, like the shoes were no kind of obstacle at all. Told me he didn't say anything to the man. Just kept walking and hoped to himself that Bear Lake was as far as the guy was planning to go. Said the thought of those flip-flops anywhere past Nymph Lake, on the climb up toward Dream, was enough to put him off his coffee for a minute. Said the rest of the hike made up for it. A cow moose and her calf working through the willows near Sprague Lake, taking their time about it. Mule deer with a fawn tucked against a downed log not far past that, the fawn doing the thing fawns do where they hold so still they look painted on. He came around a bend later and spotted a cow elk standing alone in a meadow, which these days means one thing. He gave her the whole meadow and then some. Baby season runs through the valley right now, and a cow elk by herself usually has a calf hidden close by that you can't see. Keep your distance, keep dogs leashed, and if a lone cow is standing her ground, that's not an invitation. Trail Ridge Road is open. The bighorn are at Sheep Lakes. This is a good week to be in Estes Park, as long as you give the mothers their room.
SIT DOWN. THIS ONE'S GOOD. |

What Is the Flip-Flop Migration?
Every June, a specific kind of visitor shows up in Estes Park, and you can spot them before they open the car door.
It's the footwear that gives it away first. Flip-flops on a trail meant for real boots. A cotton hoodie packed for a mountain town that can drop twenty degrees between breakfast and lunch. A gas station soda the size of a fire extinguisher, treated like a legitimate hydration plan at 7,500 feet. Locals have watched the pattern long enough to know it isn't random. It's a season, and it starts almost exactly when school lets out. How Long Has This Migration Actually Been Happening?The flip-flops are new. The migration is not.
Long before rental SUVs and cell phone maps, people were making this same trip by train and wagon, at a fraction of the speed and considerably worse suspension. Joel Estes found this valley in 1859 on a hunting trip and decided it was worth living in, moving his family of thirteen children into the valley the following year. The winters wore him down fast. By 1866, he traded the entire claim for two oxen and left for good.
Estes didn't stay long, but the people who came after him kept arriving anyway, drawn by the same thing that pulls in the flip-flop crowd today. Downtown grew up around that traffic. Outfitters to get visitors into the hills. Cafes to feed them when they came back out. Cabins, then motels, then condos hugging the hillside, each one built by somebody who fell for the valley on a short trip and wanted a reason to make it longer. How Many People Actually Come Through Here Now?The numbers explain why the sidewalks feel different in June than they do in February.
Rocky Mountain National Park draws more than 3.3 million visitors in a typical recent year, and the overwhelming majority of them funnel through Estes Park to get there. The town's year-round population sits a little over 6,300 people. For a few months each summer, the valley hosts a daily crowd that outnumbers its own residents many times over, all moving through the same handful of downtown blocks to reach the same handful of entrance stations.
That math is exactly why the timed entry reservation system exists in the first place. The park tested several approaches to managing the crowding, and the results were clear enough that the Day Use Visitor Access Plan, was finalized in May 2024, making the reservation system permanent rather than a pilot program.

Trivia Question❓Joel Estes traded his entire valley claim in 1866 for two oxen. Roughly how much would two oxen have actually been worth in cash at the time, and what drove him to make that trade? Answer at the bottom of the newsletter |

RMNP UPDATE
Trail Ridge Road is open to through travel. Timed entry reservations are required between 9 a.m. and 2 p.m. for general park access, and between 5 a.m. and 6 p.m. for the Bear Lake Road Corridor, through mid-October. Reservations for July dates were released June 1 on Recreation.gov, and any unsold slots for a given day go up at 7 p.m. the night before.
Old Fall River Road remains closed to vehicles for spring maintenance. The historic dirt section is shut to all uses, including hikers and cyclists, Tuesday through Friday from 6 a.m. to 4:30 p.m., through the rest of June. It typically reopens to cars in early July.
Bighorn sheep are making their seasonal trips down to Sheep Lakes in Horseshoe Park, usually sometime between 9 a.m. and 3 p.m. Elk, moose, and deer are also calving and fawning right now, which means cow elk and moose are unusually protective and can charge with little warning. Park officials recommend staying at least 75 feet back from any large animal, more if you can manage it, and never approaching a lone cow even if she seems calm. Keep dogs leashed at all times. . |
DID YOU KNOW?
Park officials recommend staying at least 75 feet away from elk and other large wildlife during calving season, and remind visitors that the better question isn't how close you can get, but how far back you can stay.
Rocky Mountain National Park draws more than 3.3 million visitors in a typical recent year, while the town of Estes Park itself has a year round population a little over 6,300. For a few months each summer, daily visitor traffic through town outnumbers full time residents many times over.
The timed entry reservation system now in place grew out of pilot programs the park ran between 2016 and 2023, before the Day Use Visitor Access Plan made the system permanent starting in 2024. Joel Estes moved his family of thirteen children into the valley in 1860, only six years before deciding the winters weren't worth it and trading the entire claim away. |
Buck's Joke Of The Day |
What do you call a tourist who shows up at the entrance station with no reservation and total confidence?
Early.😂 |
💡 Answer to Trivia Question: Two oxen in 1866 were worth somewhere in the range of 150 to 200 dollars, a meaningful sum for the era but nowhere near the value of an entire mountain valley. Joel Estes made the trade anyway because six winters of brutal cold and isolation had worn him down faster than the land's worth could keep pace with. |
UNTIL NEXT WEEK Saw Moe again that evening and asked if he ever found out how far flip-flop man made it.
He said no, never saw him again after the trail forked toward Bear Lake. Said he chose to believe the man had the good sense to turn around there and call it a win.
I told him that was a generous thing to believe about a stranger. He said somebody's got to be. Then he told me about the moose calf again, like it was the better story all along.
Trail Ridge Road is open. The bighorn are at Sheep Lakes. The elk, moose, and deer have their young with them now, so give the mothers room. The coffee is hot and the week is done.
Stay smart, stay safe, and leave the mountains exactly as crowded as you found them, and twice as well understood. . .- Buck Timber The Mountain Thread themountainthread.com/signup |
This account draws from National Park Service records, Colorado Parks and Wildlife public safety alerts, and local observation of downtown Estes Park traffic patterns during peak season. The broad facts are solid. The man in flip-flops is a composite, but every local has met him. - Buck |
