Soa is an uninhabited tidal island off the coast of Tiree,[1] to the south of the settlement of Ruaig.
At low tide it is joined to mainland Tiree by a sand tombolo and numerous rocky outcrops. The largest of the rock platforms, Carsamull is itself a little island at high tide.
Soa is not populated and probably never was on a permanent basis, but a former building has been identified on the south-eastern limb (Eilean an Triogh)
There is also a track which runs along the northern coast of Soa.
