Overtourism has become one of the most pressing challenges for Europe’s many popular destinations. From housing crises to overcrowded streets and strained resources, the influx of tourists has created significant challenges for locals and ecosystems alike. While travel can bring economic benefits, it is clear that unchecked tourism comes at a cost.
At CAS Trips, we believe in finding better ways to explore the world. By integrating sustainable travel practices and focusing on local connections, our trips aim to mitigate the harmful effects of overtourism in Europe. Whether it is rethinking accommodations, avoiding high season travel, or collaborating with community partners, we are committed to creating a meaningful travel experience that supports the places we visit.

The Impact of Overtourism in European Cities
Overtourism has left a significant mark on cities like Lisbon, Amsterdam, Athens, and Barcelona. Among the key challenges are:
- Housing crises: The rise of short-term rentals for tourists has driven up housing costs, making it difficult for locals to find affordable homes.
- Peak season pressures: High seasons often see an overwhelming number of visitors, putting undue strain on local infrastructure and resources.
- Cultural dilution: In some areas, tourist demand has replaced authentic local experiences with commercialized versions of culture.
Ways CAS Trips Combats Overtourism
1. Prioritizing Shoulder Seasons Over High Seasons
Traveling during the shoulder seasons helps reduce strain on infrastructure and provides a more authentic experience for students. CAS Trips supports schools in scheduling itineraries strategically to avoid peak travel periods.
2. Supporting Local Businesses
We work directly with locally owned businesses to create itineraries that channel economic benefits back into the community. By avoiding large international chains, we ensure that every trip supports authentic, community-driven experiences.
3. Avoiding Short-Term Rental Impacts
CAS Trips steers clear of accommodations that contribute to housing crises caused by short-term rentals. Instead, we aim to partner with locally owned hotels and hostels, ensuring our presence doesn’t displace local residents.

City-Specific Highlights that Address Overtourism in Europe
Barcelona: Experiencing the City Like a Local
- Partnering with local guides through organizations, who offer an insider’s perspective.
- Activities include sustainable cooking workshops, learning about Barcelona’s art and architectural history, and participating in local initiatives like beach clean-ups and supporting an organic farm.
Lisbon: Shining a Spotlight on Overtourism and the Housing Crisis
- Workshops that educate students about the impact of short-term rentals and gentrification on locals.
- Opportunities to work with NGOs that focus on housing advocacy.
- Exploring lesser-known neighborhoods to reduce the strain on over-visited areas like Alfama.
Amsterdam: Balancing Tourism and Sustainability
- Visits to sustainable projects such as food waste initiatives and textile upcycling.
- Cycling tours that focus on exploring the city’s eco-conscious efforts rather than crowded tourist hotspots.
- Collaborative projects between local residents and our groups with unique community projects alongside local residents.
Athens: Preserving History Without Overwhelming It
- Focus on small-group visits to historical sites during less crowded times and exploring areas beyond the historical center, such as Exarchia or Glyfada to experience a more authentic side of the city.
- Collaboration with local artisans and small businesses to ensure the community directly benefits from tourism.
- Promote walking tours, as Athens is a highly walkable city, allowing students to explore on foot while occasionally using public transport when necessary.

Encouraging Students to Become Responsible Travelers
At CAS Trips, we believe that responsible travel is a learned skill. Our workshops and experiences empower students to understand the effects of overtourism in Europe and the importance of sustainability. By integrating these lessons into our trips, we help create future global citizens who travel thoughtfully and with purpose.
Our students have gone on to inspire change in their own communities, from campaigns to reduce short-term rental use to innovative ideas for sustainable tourism projects. Every CAS Trip is not only an opportunity to explore but also a chance to learn and grow.
Travel has the power to transform perspectives, but it should never come at the expense of local communities. At CAS Trips, we’re proud to lead by example, offering educational experiences that prioritize sustainability and respect. By addressing overtourism in Europe head-on, we’re shaping a new generation of responsible travelers and proving that meaningful travel can also be ethical travel.
Join us in making travel a force for good.
