Puig de l'Artiga del Rei, Mountain summit on the French-Spanish border in Prats-de-Mollo-la-Preste and Molló

Puig de l'Artiga del Rei, also called Puig del Rei, is a 1,640-metre summit on the border between the municipalities of Molló, in the Ripollès comarca, and Prats de Molló i la Presta, in Vallespir, Northern Catalonia. It lies in the south-western sector of the French commune and the north-eastern sector of the Spanish one, east of the Coll de Maçanells, west of the Coll Pregon and north-west of the village of Espinavell.

The territory surrounding this peak was contested until the Treaty of the Pyrenees in 1659 formally established the border between the two nations. This agreement permanently affected how mountain communities on both sides interacted and managed their lands.

The name Artiga del Rei refers to a cleared pasture, and the summit marks the meeting point of Molló and Prats de Molló i la Presta. It is a frequent stop on hiking routes of the Canigó massif, lying east of the Coll de Maçanells and west of the Coll Pregon, northwest of Espinavell.

Marked hiking trails lead to the summit from both Prats-de-Mollo-la-Preste and Molló, with paths maintained throughout the year. Starting from either village gives visitors options to explore different routes up the mountain.

The name Artiga del Rei refers to cleared pastureland, and the summit sits between the Coll de Maçanells to the west and the Coll Pregon to the east. The village of Espinavell lies to its south-east, in Molló, while the northern slope belongs to Prats de Molló i la Presta.
