September is one of the easiest months to explore Europe. Summer crowds begin to thin, temperatures are generally more comfortable and many destinations are still warm enough for outdoor activities.

From English villages and Croatian cycling routes to volcanic hikes and Mediterranean sailing, these six places work particularly well for an early-autumn trip.

Cotswolds, UK

The Cotswolds are ideal for travellers who want picturesque villages and long countryside walks. Castle Combe and Bourton-on-the-Water remain popular, but the region’s extensive network of footpaths makes it easy to escape the busiest spots.

The 164km Cotswold Way links Chipping Campden with Bath, while September also brings the first autumn colour to local gardens.

Westonbirt Arboretum enters its peak autumn pricing period from 25 September: adults admission costs about €22 on weekdays and €26 at weekends. Batsford Arboretum is cheaper at roughly €12.70 for a standard ticket and is open until 5pm.

Istria, Croatia

September is particularly rewarding in Istria, when grape harvesting begins and truffles appear in the forests. Cycling is one of the best ways to explore the peninsula, with the 123km Parenzana Trail following an old railway route between Trieste and Poreč.

Rovinj offers colourful Venetian architecture, while Motovun and Buzet are good bases for exploring the inland hills. In Pula, the Roman amphitheatre remains one of the region’s major historic attractions.

Admission to Pula Arena currently costs €10 for adults and €5 for students. In September, the site is open from 8am to 9pm.

La Palma, Spain

La Palma is one of the Canary Islands’ strongest hiking destinations, with around 1,000km of trails crossing volcanic landscapes, pine forests and steep mountain terrain.

Caldera de Taburiente National Park is the highlight. Access to the park is free, and the El Paso visitor centre is also free to enter. If you are driving to the popular La Cumbrecita viewpoint between 8.30am and 4pm, however, you need to reserve one of the limited parking spaces in advance. The reservation itself is free.

For a more demanding day, allow seven to eight hours for the longer route through the interior of the caldera.

Bologna, Italy

September suits Bologna particularly well because outdoor dining remains pleasant while autumn ingredients such as mushrooms, pumpkin and chestnuts begin appearing on menus and market stalls.

Between meals, explore Piazza Maggiore, the Fountain of Neptune and the Quadrilatero food district. The Civic Archaeological Museum costs €6 for a standard ticket.

One important 2026 update: the Asinelli Tower is currently closed for maintenance, so the famous 498-step climb is not available. For panoramic views, the Clock Tower in Piazza Maggiore is the practical alternative. Admission costs €10, and from 7 September the last entry is at 6.20pm.

Turquoise Coast, Türkiye

September remains warm along Türkiye’s Turquoise Coast, but temperatures and visitor numbers are usually more comfortable than during the height of summer.

Bodrum, Marmaris and Fethiye are major starting points for cruises along the Aegean and Mediterranean coastlines. Trips combine swimming stops, quiet bays and visits to historic sites.

For travellers watching their budget, shared boat trips from Fethiye are advertised at roughly €35–55 per person for a full-day outing, depending on the vessel and season.

Transylvania, Romania

Romania’s Transfăgărășan Highway is one of Europe’s most dramatic mountain drives, winding past Bâlea Waterfall and Bâlea Lake before descending towards Curtea de Argeș.

As of 16 September 2026, the road is open, although conditions can change quickly at high altitude.

The Bâlea cable car runs daily from 9am to 6pm. The ticket costs about €15 one way or €30 return, while parking at the lower station is free.

September is especially attractive because mountain scenery begins to shift towards autumn colours, but drivers should check conditions before setting out.

Europe in September offers a useful balance between summer weather and autumn calm. Whether you prefer hiking, cycling, food-focused city breaks or coastal trips, travelling after the peak season can make both sightseeing and accommodation noticeably easier.
