La côte Est présente une débauche de végétation buissonnante. Les rares parties négligées par la broussaille sont colonisées par des fougères et divers chardons. Le prunellier se bagarre avec le sureau, le chèvrefeuille avec le liseron ; partout, jusque dans les genêts, il y a surabondance de vrilles. Cet endroit est un des plus vert de l'île.
The eastern coast shows an abundance of bushy vegetation. The rare areas ignored by the undergrowth are colonized by ferns and various thistles. The sloe brawls with the elder, the honeysuckle with the bindweed; everywhere, even in the brooms, there is superabundance of gimlets. This place is one of greenest of the island.

A thistle in a dry ravine: Dipsacus cf. sativus Lin. syn: fullonum. The island is notched by dozens of these small valleys, which make it difficult to ride across: flat parts are uncommon, and the wind always blows from the wrong side.

The Sables Blancs. This beach has the effect of being itinerant: pushed by two opposed currents, it fluctuates between Fort Surville and the Trec'h. In this area, the sea is often quiet enough to allow yachts to anchor.

Les Sables Rouges. At the foot of Nosterven hill, a small beach of white sand is covered by a fine and lighter layer of red sands. Tectura virginea (O.F. Müller 1776) on a Callista chione (Linnæus 1758). This one is 5mm long.
