Discover where to travel in September, from Vietnam touring and Portugal’s harvest season to Greece’s warm seas, USA road trips and Morocco’s comfortable heat.
In September, summer crowds begin to thin across southern Europe, temperatures soften and landscapes settle into a more relaxed rhythm.
Touring conditions become far more comfortable after the intensity of high summer in North Africa, while outdoor exploration remains in full swing across much of North America.
If you’re wondering where to travel in September, this is when you can explore popular destinations without the intensity of peak summer.
You can wander coastal villages in Portugal, explore Greek islands without peak season crowds, tour Morocco’s imperial cities in manageable heat or combine road trips and national parks in the USA.
Further east, Vietnam offers improving conditions in several key regions. It’s easy to see why these are among the best places to visit in September for relaxed, well paced travel.
Vietnam in September: Regional contrasts and cultural depth
September brings mixed but increasingly favourable conditions across Vietnam. In the north, Hanoi and Sapa begin to transition away from peak summer heat, and terraced rice fields around Mu Cang Chai turn vibrant green and gold as harvest approaches.
Central areas such as Hoi An can still see rainfall, though quieter streets allow for more relaxed exploration. In the south, Ho Chi Minh City remains lively despite intermittent showers. By focusing on the right regions, you can shape a varied itinerary that blends cuisine, history and scenery.
If you’re weighing up where to visit in September for cultural immersion in Southeast Asia, Vietnam is a really strong choice.
Portugal in September: Atlantic light and vineyard season
Golden light lingers across Portugal in September. Along the Algarve, sea temperatures remain inviting after the summer peak, while crowds ease from their August high. In Lisbon and Porto, you can explore historic neighbourhoods and waterfront districts without the intensity of midsummer heat.
The Douro Valley enters harvest season, bringing activity to vineyard terraces that overlook the river. Coastal walks and seafood lunches feel unhurried at this time of year.
If you’re considering where to go on holiday in September for coastal scenery paired with food and wine, Portugal feels especially well timed.
Greece in September: Warm seas and quieter islands
Late summer warmth continues across Greece, yet the atmosphere shifts as peak holiday numbers begin to fall. Sea temperatures remain high, which makes swimming and boat excursions particularly appealing around islands such as Crete, Naxos and Rhodes.
Inland archaeological sites are easier to explore in slightly milder daytime conditions. Evening dining stretches comfortably into the night without the relentless heat of July and August.
If you’re searching for the best September destinations for enjoying the Mediterranean coastline with a little more breathing space, Greece provides a lovely blend of climate and calm.
USA in September: Open roads and early autumn colour
Across much of the United States, September signals a welcome transition. National parks such as Yellowstone and Yosemite remain accessible, yet visitor numbers often drop after the summer rush.
In New England, the first hints of autumn colour begin to appear, while the Pacific Northwest enjoys clear skies and moderate temperatures for hiking. Cities including Chicago and San Francisco feel energised but not overcrowded.
With varied climates across regions, you can tailor your route to match your interests. If expansive landscapes and cultural diversity appeal to you, the USA ranks among the best places to visit in September.
Morocco in September: Imperial cities in comfortable heat
As summer intensity fades, Morocco becomes far more manageable for touring. In Marrakech and Fes, daytime temperatures ease compared to July and August, making time in the medina more enjoyable.
The Atlas Mountains offer cooler air for hiking, and the Atlantic coast around Essaouira benefits from steady breezes. Desert excursions are still possible, particularly with early morning departures. Markets remain vibrant, yet the atmosphere feels less hurried than at peak heat.
If you’re deciding where to travel in September for cultural depth in North Africa, Morocco strikes a confident balance between warmth and comfort.

Most journeys are designed to get you somewhere as quickly as possible. The Blue Train does the opposite. Over three days and two nights, it travels roughly 1,600 kilometres between Pretoria and Cape Town, turning the distance between the two cities into an experience in its own right.
Europe is packed with iconic destinations, but some of its most rewarding holidays begin just beyond the well-trodden tourist trail. If you've already ticked off the big-name cities or simply fancy somewhere that feels a little different, there are plenty of places offering beautiful scenery, fascinating history, and memorable food without the queues. From medieval towns on the Adriatic coast to volcanic islands in the Atlantic, these lesser-known corners of Europe prove that sometimes the best trips are the ones you weren't expecting.
Summer might get most of the attention, but autumn can be one of the most rewarding times of year to travel. Cooler temperatures make days outdoors more comfortable, landscapes shift into rich seasonal colours, and many destinations settle into a quieter rhythm once the peak summer crowds have gone. That’s where the ‘cool-cation’ comes in. Instead of chasing the heat, these trips are all about crisp mountain air, lakeside walks, dramatic scenery, cosy food, and the kind of weather that makes you want to pull on another layer and keep exploring. From the Italian Alps to the Canadian Rockies, here are seven destinations that come into their own in autumn.
