Roca d'en Toni is the best-known megalithic tomb in the Maresme area, set in the hills of the Serralada Litoral above Argentona and Vilassar de Dalt. The granite slabs form a small corridor tomb, modest in scale but atmospheric in its wooded setting.
It is worth including on a walk through the natural park, especially if you are already linking the prehistoric sites, old farm tracks, and hill views around Burriac. Come for a short stop rather than a major archaeological site.
