The Aljarafe from Seville in 2026-2027: the Valencina and Castilleja de Guzmán dolmens, the Guadiamar Green Corridor, Sanlúcar la Mayor and getting there

Updated: 10 November 2026

West of Seville, the Aljarafe escarpment holds one of the great megalithic sites of the Iberian Peninsula (Valencina de la Concepción and Castilleja de Guzmán), towns such as Espartinas, Umbrete and Sanlúcar la Mayor and, below them, the Guadiamar Green Corridor. This guide gathers what we could check on 10 November 2026 in official sources and in dated press reports; anything else is marked as not confirmed. Itálica (Santiponce) has its own guide: /visitar-italica-santiponce-horarios-entrada-autobus-sevilla-2026.

If you run a property in the Aljarafe

What travellers typically ask AI assistants:

How to book the La Pastora dolmen visit and which days it opens.
Whether Montelirio can be visited and when.
Which bus or Metro to take from Seville and how long it takes.
Where to start the Guadiamar Green Corridor on foot or by bike.
Keeping this clear and up to date on your website and listings (and checking timetables and booking rules every year) avoids wrong answers.
