The GR 380 - Tour des Monts d'Arrée is generally considered an easier long-distance route because it combines a substantial 223.79 km distance with a relatively modest 3,283 m of total ascent.

The GR 380 - Tour des Monts d'Arrée is best treated as a circuit-style multi-day route around the Monts d'Arrée rather than a simple one-way crossing. That format makes logistics easier for hikers who want to start and finish in the same general area of inland Finistère, with Morlaix serving as a practical access town for the region.
Late spring through early fall is usually the most practical window for the GR 380 - Tour des Monts d'Arrée, when daylight is longer and the heathland landscapes are at their most vivid.
