The Mediterranean is the original group trip destination, and this itinerary gives you two of its best cities in one week. Barcelona delivers Gaudi's surreal architecture, a food scene that peaks somewhere between a cava bar at midnight and a 2 PM tapas crawl, and a beach that lets you combine culture with actual relaxation. Split gives you a living Roman palace, crystal-clear Adriatic water, and an island-hopping scene that rivals the Greek islands at half the price.
The mid-week flight from Barcelona to Split costs 50-150 euros on budget carriers and takes about 2.5 hours. You cross from Spain's Atlantic-influenced Mediterranean coast to Croatia's Adriatic coast, and the change in pace is immediately noticeable: Split is slower, quieter, and more focused on the water.
This itinerary works well for couples, friend groups, and adventurous families. Budget travelers can cover the week for $1,500 per person by staying in hostels and eating at markets. Mid-range travelers spending $2,500-3,000 get boutique hotels, sit-down restaurants, and the Hvar day trip without watching every euro.
