As the autumn chill sets in many of us get the itch to go away one last time before the year ends. Although sun-seekers may be hard-pressed to find an autumnal getaway with the weather they want, there is a grand city that has much more to offer than sandy beaches.

You can explore its string of islands with no car; and for those who still want a seaside fix, you can enjoy the ocean from the warmth of a hot tub. The city is Gothenburg in Sweden, which the United Nations has officially declared as the new host city for its Sustainable Lifestyle Hub. This honour places the Swedish city at the forefront of climate-smart living. It also presents a unique opportunity for travellers to visit and experience the city that's moulding the future of travel.

From commuting on a public transport network powered by 95% renewable energy to exploring the car-free southern Gothenburg archipelago, here are the top ways to relish a sustainable city break in Gothenburg.

Getting to Gothenburg doesn't necessarily mean flying; from London, you can reach Sweden entirely by rail in less than 24 hours.

For those choosing to fly, Gothenburg's Landvetter Airport is just 25 minutes from the city and is well connected by public transport, meaning you can enjoy a car-free stay from the moment you touch down.

A whopping 95% of Gothenburg's public transport is powered by renewable energy. Plus, trams, buses and boats are always included in travel, regardless of which ticket or public transport card you use.

Gothenburg, being compact, flat and bike-friendly, is also perfect for cycling, which is why many visitors hire a bike to explore the city's waterfront and green spaces.

By 2025, a staggering 96% of hotel rooms in Gothenburg will be eco-certified, one of the highest rates globally. From chic boutique accommodations like Jacy'z Hotel and Resort to larger chain establishments, such as the new Scandic Europa, holidaymakers can opt for hotels dedicated to recycling, energy efficiency, and sustainable operations without compromising on comfort.

For a luxurious wellness accommodation option, consider the new Kusthotellet Styrsö.

Just half an hour from the city centre, ferries transport you to Gothenburg's southern archipelago, which is a series of car-free islands.

Once there, tourists can trek along coastal trails, bask on sandy beaches or take a dip off granite rocks - all devoid of traffic. It's slow, sustainable travel at its finest, right on the city's doorstep.

The city has subtly positioned itself as Sweden's gastronomic capital. Food enthusiasts can relish Gothenburg's status as Sweden's culinary capital, with an increasing number of Michelin-starred restaurants.

Enjoy a meal at the award-winning Signum, or taste fresh shellfish at the newly refurbished Feskekörka fish market.

Gothenburg is leading the way in the circular economy, making shopping a sustainable activity. Browse vintage boutiques, second-hand shops and design stores that champion reuse and upcycling.

The city also backs over 100 sharing initiatives, from tool libraries to clothing rentals, making it a hub for conscious consumption.

Experience a truly Swedish ritual by combining an invigorating sea swim with a restorative sauna session. Gothenburg offers everything from urban harbour saunas made from reclaimed materials to wood-fired saunas on the archipelago.
