Experience Responsible and Sustainable Tourism with Us
A Green B&B
At Casa do Valle, we are on a mission to make tourism more responsible and sustainable, and we invite you
to join us on this incredible journey. Your holiday experience matters, not just to you but to the world we
all share. That´s why we are committed to offering you a unique and eco-conscious adventure.
Sustainable Responsibility

Climate & Environmental Responsibility
At Casa do Valle, we are committed to minimizing our environmental impact by reducing our carbon footprint and actively participating in sustainability projects. Our mission is to ensure that the beautiful places we take you to remain pristine for generations to come.
We are in harmony with nature, especially the stunning Serra de Sintra. We celebrate its beauty and are dedicated to caring for it. We encourage activities like walking, hiking, cycling, climbing, and surfing – all with a low Carbon Footprint. Our preferred modes of transport are bicycles and walking. We even volunteer to maintain walking trails in Sintra.
We proudly hold the Green Key eco-label, which transmits our commitment to numerous environmental requirements, including waste reduction, energy and water conservation, and using eco-friendly products. When you choose to stay with us, you are actively contributing to environmental protection.
Social Responsibility - People and Society
We are proud to be a part of the Sintra community, and we celebrate the diversity of small businesses around us. That is why we support local farmers, use locally made products, and suggest gifts from local small businesses.
In terms of caring for our community, we support local charities, and unused individual body lotions and shampoos go to the homeless in Lisbon.
We believe in investing in our people. As a small community, our future success depends on a skilled and motivated workforce. That’s why we strive to create a work environment that’s enjoyable and motivating for our employees.


Economic & Financial Responsibility
Casa do Valle is a small Portuguese company that pays taxes in Portugal. We understand that financial responsibility is key to maintaining our environmental and social commitments.
We are open year-round, providing stability for our staff and ensuring the upkeep of our rooms and facilities. We prioritize long-term employment contracts with local residents.
When you choose to stay with us, you are not only experiencing a beautiful holiday but also contributing to the local economy and community.
Walk Sintra Project
This is our crowning achievement! We created Walk Sintra to make it more convenient and safe, not only for our guests, but for all visitors to the region, to explore all corners of Sintra. Our goal is not only to help you explore the well-known center with its palaces and monuments by foot through the suggested trails and paths but also to inspire you to uncover the lesser-known areas.
You can access various routes and Sintra-related information through our free app, available for download on both the Apple Store and Play Store.
