A dense cluster of trees rises from the center of the composition, their foliage rendered in layered strokes of deep green, blue, and hints of violet. The reflection of the trees in the river appears as a shimmering mirror image, broken by gentle ripples that Monet suggests with loose, horizontal brushwork. To the left and right, the riverbank recedes into the distance, where more trees dissolve into a haze of blue and green, their forms softened by atmospheric perspective.

Above, the sky is pale and luminous, painted with broad, feathery strokes of white, blue, and touches of pink, suggesting a light-filled day with thin clouds. The brushwork is varied and expressive: short, swirling marks evoke the dense leaves, while longer, smoother strokes describe the tranquil surface of the water. The palette is cool and harmonious, dominated by greens and blues, with subtle variations that capture the shifting light and reflections.

No human figures, boats, or animals are visible anywhere in the composition, emphasizing the solitude of the scene. The upper right and left corners of the painting show the sky fading into soft, pale tones, with the paint thinned and the canvas texture subtly visible. Along the bottom edge, the water’s surface is rendered with horizontal strokes of blue, green, and pale yellow, creating a sense of gentle movement.

Loose, swirling brushwork in the central mass of trees creates a tactile, almost sculpted effect, while the distant background trees are painted with lighter, more diffuse strokes. Claude Monet painted Les Îles de Port-Villez in 1883. The Sotheby’s collection lists this painting under Monet’s name and confirms its date as 1883.
