Hvar was definitely lovely but much louder at night, with more people. But there was a nice walk/hike up to the fortress than I didn't do but it didn't look very crowded. Split and Zadar were, for me, different. Zadar's old city center is flat, has a day's worth of walking and things to see.

Choosing between Zadar and Hvar depends on whether you seek historic authenticity or glamorous island vibes. Zadar is the "gold standard" for travelers who want a more "local" feel with Roman ruins, the unique Sea Organ, and world-class sunsets, all at a lower price point than the islands. It is a fantastic base for exploring national parks like Plitvice or Krka. Hvar, specifically Hvar Town, is the premier destination for nightlife, luxury yachting, and high-end beach clubs. It is significantly more expensive and crowded, but it offers stunning turquoise waters and a "jet-set" atmosphere that Zadar lacks. In 2026, Zadar is often preferred by families and budget-conscious travelers, while Hvar is the choice for honeymooners and party-goers. If you want a mix of both, the "pro-tip" is to stay in Zadar for the culture and then take a catamaran to the Pakleni Islands near Hvar for a day. Ultimately, Zadar feels like a "real" Croatian city, while Hvar feels like a beautifully curated Mediterranean playground, making the "better" choice entirely dependent on your desired pace.
