Terheldjön

Terheldjön is a small island located in the archipelago of Åland, Finland. It is situated within the municipality of Kumlinge. The island's terrain is characterized by rocky shores, sparse vegetation typical of the Baltic Sea region, and a relatively flat topography. Terheldjön is largely uninhabited, serving primarily as a natural area with a limited human presence.

The island's ecological significance lies in its role as a habitat for various species of birds, particularly those adapted to coastal and marine environments. The surrounding waters are also home to fish populations that are part of the local ecosystem. Due to its remoteness and lack of infrastructure, Terheldjön remains a relatively untouched natural landscape.

Access to Terheldjön is typically by private boat, as there are no regular ferry services. Its isolation contributes to its tranquil atmosphere and makes it a destination for those seeking solitude and an experience of the natural Åland archipelago. The island does not feature any permanent settlements or public facilities, reinforcing its status as a natural preserve rather than a developed tourist spot.
