Andalusia itinerary advice — 4 full days with 9 people (Seville, Granada, Gibraltar?)

We’re planning a family trip to Andalusia and I’d really appreciate some itinerary advice from people familiar with the region.

We’re two families traveling together, 9 people total, with 4 full days / 3 nights. We arrive in Seville early morning on June 24 and fly back from Seville late evening on June 27, so we effectively have four full sightseeing days.

Our absolute must-sees are Seville and Granada (especially the Alhambra). We’re also considering Gibraltar as an additional stop.

We’re okay with a fairly packed itinerary and don’t mind moving between cities or changing accommodation if it makes sense logistically. We’ll likely rent a car.

Main interests are:

• sightseeing (cities, architecture, viewpoints)
• history and local culture
• iconic Andalusia highlights
• maybe one scenic hike if it fits the route (e.g. Caminito del Rey near Ronda)

We’re not really focused on beaches or nightlife. Heat in late June is not a major concern for us.

How would you structure these 4 days? What would you prioritize and what would you skip?

At the moment I’m thinking something like:

• Seville
• Granada (Alhambra)
• Ronda
• Gibraltar
• possibly Córdoba

But I’m worried this might be too much for 4 days. Would really appreciate any suggestions on how to optimize the route or make it more realistic.

Thanks in advance!
