The 35th Orkney International Science Festival will return this year with another packed programme.

Over the years the festival has developed a distinctive feel, with family activities, music, and food and drink events amongst the varied talks by speakers.

2025's programme will see the usual eclectic mix of talks, walks, workshops, exhibitions and concerts. As always, some special settings will be included in the schedule, including the Hoy Kirk Heritage Centre, the Ness of Brodgar, and the Barony Mill.

Topics include astronomy, ancient Orkney, and geology, from the mountains by Berriedale and Helmsdale to the shores of Shapinsay and Hoy Sound. There will also be stories from Orkney folklore of submerged forests and a look at ancient sheep breeds in Nordic lands – and new markets for their meat and wool today. Orkney's first-ever Orkney Climate COP will be held too, with speakers tackling subjects including energy, food, housing, and transport.

There are musical performances in St Magnus Cathedral, and the usual celebration of Orkney's food and drink too.
