Welcome to the Osea Island Website
Hello and welcome to the world’s only island dedicated to addiction treatment and mental health; Osea Island’s website. In the upcoming days, we are going to introduce you the beauty of this island and give you more information about the island’s history, current situation and the facilities in this beautiful private island retreat.
Thanks for visiting the website and we hope you will enjoy it.

I have sailed around the Island, is it possible to venture further inshore or even stay in the Cotteges. Trestment not required as yet fortunately !!
Hello Alan,
I’m afraid it is not possible to stay on the island for leisure purposes. The entire island is now an addiction treatment and mental health care clinic and is only being used by the patients.
Kind regards,
Osea Island Administration.
