Porto, Portugal’s second-largest city, is a vibrant blend of history, culture, and creativity. But beyond the postcard-perfect views and iconic blue tiles lies a new way to explore the city—through mindful, sustainable, and community-driven experiences. At 21 Sensations, we believe in travel that leaves a positive footprint. That’s why we’ve curated this guide to eco-friendly and conscious Things To Do In Porto, perfect for travelers who want to connect deeply with the city while respecting its people and planet.
Discover Porto by Foot or Bike
One of the most eco-conscious things to do in Porto is simply to explore it without a car. The city’s compact layout and walkable neighborhoods make it ideal for discovering on foot. Wander through Ribeira, get lost in the labyrinthine streets of Miragaia, or hike up to the gardens of Palácio de Cristal for sweeping views of the Douro River.
For a greener and faster option, rent a bike from a local company like Bluesock Bikes or Vieguini, which both promote low-impact urban mobility. Whether cycling along the Douro or coasting toward the oceanfront in Foz, biking is one of the most rewarding things to do in Porto for the eco-conscious traveler.
Eat Plant-Based at Local Cafés
Choosing plant-based meals is a powerful way to travel more sustainably. Thankfully, Porto’s culinary scene is evolving fast. For conscious food lovers, this is one of the most satisfying things to do in Porto.
Check out DaTerra, a buffet-style vegetarian restaurant using mostly organic and local produce. Or head to O Diplomata, a charming café with excellent vegan pancakes and eco-conscious coffee. By supporting plant-forward eateries, you’re also supporting a more sustainable food system—one bite at a time.
Shop Local & Ethical
Support local artisans and ethical brands by choosing handmade and locally produced items instead of mass-produced souvenirs. This is not only one of the most ethical things to do in Porto, but also one of the most meaningful.
Visit Coração Alecrim, a boutique filled with Portuguese-made eco-products, upcycled fashion, and artisanal goods. Or browse Patch Lifestyle, a concept store featuring sustainable home decor and beauty brands. These places are redefining the way we shop and encouraging more conscious consumerism in Porto.
Stay Green: Eco-Friendly Accommodations
Eco-conscious travel doesn’t stop when the day ends. Choosing where you sleep is one of the most impactful things to do in Porto. Opt for accommodations that focus on sustainability, community, and local culture.
Zero Box Lodge is an innovative, eco-aware hotel built in a former bank, using repurposed materials and promoting local art and food. For a more intimate experience, The Passenger Hostel—housed in São Bento train station—offers a social, sustainable vibe with energy-efficient practices. These stays aren’t just places to rest—they’re part of your eco-journey.
Visit Markets that Promote Sustainability
Exploring Porto’s markets is not only a cultural experience but also one of the most sustainable things to do in Porto. Head to Mercado do Bolhão, recently restored with a deep respect for its architectural and social heritage. Here, you can connect with local farmers, buy seasonal fruits, and support family-run stalls.
For a more niche experience, Mercado da Alegria (Market of Joy) focuses on organic, fair-trade, and local products. From handmade ceramics to eco-friendly cosmetics, it’s the perfect stop for those wanting to shop with purpose.
Join Conscious Tours & Workshops
Engaging with Porto through learning and community-driven experiences is one of the most meaningful things to do in Porto. Many local initiatives now offer tours and workshops that highlight sustainability, local heritage, and slow travel values.
Portoalities offers customized walking tours focusing on hidden history and lesser-known neighborhoods. Passeio Verde organizes eco-walks through Porto’s green corridors, focusing on native plants and environmental preservation. Participating in these types of activities not only enriches your trip but also contributes to small-scale, ethical tourism.
Experience Porto’s Green Spaces
Nature is everywhere in Porto—you just need to know where to look. Enjoying the city’s parks and gardens is one of the best free things to do in Porto, especially for those looking to travel light on the earth.
Visit Jardins do Palácio de Cristal, a sprawling green space with peacocks, fountains, and panoramic river views. Or explore the Parque da Cidade, Portugal’s largest urban park, perfect for a zero-waste picnic or an early morning yoga session. These natural sanctuaries offer both tranquility and sustainability.
Support Social Enterprises
In a city as culturally rich as Porto, social tourism is gaining momentum. Contributing to social impact through travel is one of the most responsible things to do in Porto.
A Vida Portuguesa is a shop celebrating Portuguese heritage with products made using traditional techniques. Buying here supports small-scale artisans and preserves cultural identity. For coffee with a cause, visit Época, a café that focuses on traceable sourcing and inclusive hiring practices. Every euro you spend in these places supports a better, fairer future.
Reduce Plastic with Local Refilleries
A unique and responsible experience among things to do in Porto is to visit zero-waste stores and refilleries. Maria Granel, though originally from Lisbon, now partners with Porto-based initiatives to promote bulk shopping and sustainable living.
Bring your own containers to stores like Sapato Verde, which sell organic cleaning products, personal care items, and bulk grains. Even if you’re only in Porto for a few days, reducing your plastic use makes a difference.
Cruise the Douro… the Eco Way
While river cruises are a staple in Porto, opt for electric or solar-powered alternatives for a more sustainable experience. Companies like FeelDouro offer eco-friendly boat rentals and cruises that minimize environmental impact.
This conscious version of one of the most popular things to do in Porto still delivers breathtaking views and wine country charm—without contributing to emissions or water pollution.
