Educational trips

Flat Holm Island offers everything you need to explore the exhilarating world of outdoor education. Our aim is to offer Flat Holm Island as an environmental education facility, while still conserving the Island as a nature reserve.

Whether you are looking for an educational day visit or longer we will aim to cater for your needs.

Day visits include a general tour of the Island exploring its history and wildlife. Alternatively, if you are looking to complete a certain topic area we can work with you to provide some shorter education based activities. We can also develop a programme of activities for groups staying on the Island for a few nights.

We welcome university groups to carry out their own programme of studies in a range of areas, e.g. biology, marine studies, geology, art.
