Our working method


01. Inspire

Many of us dream of diving at the most beautiful dive sites in the world – a real bucket list. With the ever-growing offer on our website, we especially want to offer divers the opportunity to search in a targeted way for the trip that best suits them and allows them to realize their dreams.

02. Personal contact

We are not a large organization. We don’t want that either. Through telephone contact, a video call or a visit to our office in Utrecht, we will put together the most suitable trip for you. We also work with local dive travel consultants. The person you talk to is also the one who books everything for you and is available before, during and after the trip for questions or help. Personal advice and contact is of paramount importance to us. Our goal is to give you a beautiful and carefree diving vacation.

03. Customized proposal

After noting your needs in a personal conversation, we will work for you to create a customized proposal. We take into account your budget and specific needs, of course. Within a few business days you will receive a proposal from us by e-mail. Should you notice anything missing or something that could be improved, we are ready to optimize the proposal. We see this as an opportunity to further tailor the proposal to your needs.

04. Enjoy

Are you booking with us? Then we will take all the worries out of your hands. We are already keeping that in mind as we draft the proposal. You should be able to fully enjoy your diving vacation. No stress. Minimal transfer of flights, pleasant times and good quality accommodations and diving schools.

Many of our travelers cherish for years the memories of the wonderful diving trip they took with EWDR. We want the same for you!

He recently discovered the breathtaking underwater world of the Maldives. He is also hugely enthusiastic about the pristine beauty of Cape Verde.
