A postcard travels from Antarctica’s Penguin Post Office to Ochopee, Florida – the tiny Everglades hut known as the world’s smallest post office.
This season, UKAHT was part of another extraordinary postcard journey – this time from Port Lockroy, the world’s southernmost post office, to Ochopee in Florida, home to the smallest post office in the United States and often celebrated as the world’s smallest in the world post office.
Once again, UKAHT was delighted to work with Gerhard Freund, a keen philatelist from South Tyrol in northern Italy. Gerhard has a special interest in pushing the boundaries of global postal systems and connecting some of the world’s most unusual post offices.
Over the years, we have collaborated with Gerhard on a series of wonderfully inventive postal journeys. This latest journey, however, felt particularly special to me. That is because I was not following the story from afar. I was at Port Lockroy for the season and had the pleasure of personally writing, cancelling and posting the postcard myself.
Ochopee: the smallest post office
The destination for this journey was the Ochopee Post Office in Florida, USA. Tucked beside Route 41 in the Everglades, it is a tiny white wooden hut measuring just 61.3 square feet. The building was originally used as a storage shed for irrigation pipes on a nearby tomato farm, but was pressed into service as a post office in 1953 after a fire destroyed Ochopee’s previous post office and general store.
What began as a temporary solution became permanent. More than 70 years later, the little shed is still a fully functioning post office, serving residents across a wide rural area, including nearby Seminole and Miccosukee communities. It has just enough room inside for one postal worker, a counter and a set of mail slots.

Its tiny size has also made it a much-loved roadside landmark. Tourists, travellers and stamp collectors regularly stop by to take photographs and request the famous Ochopee postmark.
Donald Walters, the postmaster at Ochopee, kindly helped mark the arrival of our postcard and photographed it at the tiny post office. As if its size and setting were not characterful enough, the Everglades occasionally finds its way indoors too: one of Donald’s photos even shows a snake making itself at home among the mail slots.
The journey begins at Port Lockroy
The postcard began its journey at Port Lockroy on 2 January 2026. I wrote a short message on behalf of the team, stamped the card with the Port Lockroy cachet and added the date, location and HSM number.
The message read:
“Dear Postmaster!
Greetings from the world’s southernmost post office, AKA The Penguin Post Office in Antarctica!
All the best from the Port Lockroy team.
Pete, Rachel, Tiago, Amanda + Lisa”
The postcard was then placed inside an envelope addressed to Donald Walters, postmaster at Ochopee Post Office, Florida. British Antarctic Territory stamps were added and hand-cancelled at Port Lockroy, giving the envelope its first official mark of the journey.
Before posting it, I took the postcard outside Bransfield House for a final photograph at Base A. Then it went into Port Lockroy’s red post box, joining the thousands of other postcards sent from Antarctica each season.
From Antarctica to the Everglades
Mail from Port Lockroy has one of the most unusual postal routes in the world. After being cancelled, bundled and packed into mailbags, it is carried down to the landing site and collected by a visiting expedition ship.
In this case, the mailbags were collected by SH Diana, which took the post north from Goudier Island towards the Falkland Islands. From Port Lockroy’s icy harbour, the postcard travelled by sea across the Southern Ocean to Stanley, where mail from Antarctica is sorted by destination country.
From Stanley, the postcard would have joined the regular route for Port Lockroy mail, flying to RAF Brize Norton in the UK before entering the Royal Mail system. From there, it travelled by air to the United States, entered the USPS network and made its way south through Florida to Ochopee.
Finally, after travelling by ship, plane, road and hand, the postcard reached Donald Walters at the little white post office in the Everglades.
As the crow flies, Port Lockroy and Ochopee are around 10,200km (6,340 miles) apart. But postal routes are rarely direct. Following the likely route from Port Lockroy to Stanley, then via the UK and on to Florida, the postcard probably travelled around 21,800km (13,550 miles) in total – more than twice the straight-line distance.
That is an astonishing journey for one small envelope.
From one tiny post office to another
There is something rather wonderful about this particular pairing. Port Lockroy may be remote, icy and surrounded by gentoo penguins, but the post office itself is modest: a counter, a post box, stamps, mailbags and a small team carefully hand-cancelling every item of post.
Ochopee could hardly look more different. Instead of glaciers and brash ice, it sits among the warm, humid waterways of the Everglades, where alligators live nearby and snakes occasionally wander indoors. Yet it too is a tiny working post office, loved by collectors and visitors because of its scale, character and sense of place.
Both post offices remind us that mail is about more than logistics. A postcard carries a message, but it also carries a story: where it came from, who handled it, how far it travelled and the people who helped it on its way.
For me, this was a particularly lovely one to be part of. Standing at Port Lockroy, writing a message to a postmaster thousands of miles away, then stamping and posting the envelope myself, brought the whole journey to life. It was a small act of connection from one of the most remote places on Earth to one of the smallest postal outposts in the world.
UKAHT would like to thank Gerhard Freund for bringing us another imaginative postal challenge, Donald Walters for receiving and photographing the postcard in Ochopee, SH Diana for helping carry our mail north, and everyone involved in getting this little envelope from Antarctica to Florida.
From the Penguin Post Office to the smallest post office, this postcard travelled a very long way to connect two wonderfully unusual corners of the postal world.
