September is the wettest month but comfortable, good for Varazdin or Plitvice once forecasts settle.
City overview
Zagreb sits between the Sava plain and Medvednica, with a compact historic core split between hilltop Gornji Grad and tram-lined Donji Grad. The city works best as a sequence of named zones: Kaptol and St. Mark Square for old Zagreb, the Green Horseshoe for museums and parks, and Novi Zagreb or Jarun for the postwar southern side.
Food & drink
Zagreb food mixes strukli, zagrebacki odrezak, purica s mlincima, cevapi, cottage-cheese pastries, kremšnita, and strong coffee culture. Dolac Market, Tkalciceva terraces, Ilica bakeries, and old gostionica dining rooms are the easiest first-pass food map.

Neighborhoods
1Gornji Grad and Kaptol
The Upper Town feels ceremonial and compact, with St. Mark Square, Lotrščak Tower, the Stone Gate, Zagreb Cathedral, and small museum streets above the funicular.
2Donji Grad and the Green Horseshoe
Lower Town is flatter and grander, with Ban Jelačić Square, Zrinjevac, King Tomislav Square, the Botanical Garden, the theatre, galleries, and main tram lines.
3Tkalciceva and Dolac
The lane below Kaptol is cafe-heavy and social, tied to Dolac Market, Opatovina, bars, street terraces, and the climb into the Upper Town.
4Ilica and British Square
Ilica is the old shopping spine, while British Square adds Sunday antiques, neighborhood cafes, bakeries, and a more residential westward rhythm.
5Maksimir
Maksimir is green and family-focused, with the park, zoo, football stadium, lakes, and tram stops that make it easy from the center.
6Novi Zagreb, Jarun, and Bundek
South of the Sava, the city becomes modernist and open, with apartment blocks, the Museum of Contemporary Art, Jarun lake paths, Bundek lawns, and big-event spaces.
Getting around
ZET trams and buses cover the city, with Ban Jelačić Square and the main railway station acting as the useful central nodes. The Upper and Lower Town are walkable, and the short funicular saves the steepest climb to Lotrščak Tower.

City overview
Split is an Adriatic port where Diocletian Palace is not a ruin outside town but the lived-in core of the city. The practical visitor frame is the Palace and Riva for the historic center, Varos and Marjan for old lanes and viewpoints, and Bačvice or Firule for city beaches.
Food & drink
Split food is Dalmatian and coastal: pasticada with gnocchi, black risotto, grilled sardines, brudet, soparnik, blitva, fritule, and local olive oil. Pazar produce market, the fish market on Marmontova, palace konobas, and Varos taverns are the useful first stops.

6Žnjan and Trstenik
The eastern shore is more residential and modern, with long pebble beaches, seaside bars, bigger hotels, and bus links back to the palace.
Getting around
Split old center is foot-only in practice, and most ferry, bus, rail, Riva, Bačvice, and palace stops sit within a compact harbor zone. Promet buses cover Marjan edges, Znjan, Salona, Trogir, and airport approaches, while ferries and catamarans drive island travel.

City overview
Dubrovnik is a limestone-walled Adriatic city where the Stradun, old harbor, and fortresses sit between steep Mount Srd and the sea. First trips work by separating the pedestrian Old Town from the gate districts of Pile and Ploče, then using Lapad, Gruz, and Babin Kuk for beaches, buses, and ferries.
Food & drink
Dubrovnik food leans coastal, with black risotto, buzara mussels, grilled fish, zelena menestra, pasticada, rozata custard, and bitter-orange sweets. Gundulićeva Poljana market, Gruz fish market, Stradun side lanes, and Lapad restaurants are the useful food anchors.

Neighborhoods
1Old Town
The walled core is dense, polished, and pedestrian-only, with Stradun, Luza Square, churches, monasteries, steep stair lanes, and restaurant terraces inside the gates.
2Pile
Pile is the western gate area, with bus stops, Fort Lovrijenac, West Harbor, hotels, kayak launches, and the pressure point for tour arrivals.
3Ploče
Ploče climbs east of the walls toward the cable car, Banje Beach, old villas, and balconies with the postcard view back over the city.
4Lapad
Lapad is the practical beach-and-hotel district, with Uvala Lapad promenade, restaurants, swimming coves, and buses into Pile.
5Gruž
Gruz is working Dubrovnik, with the ferry port, bus station, fish market, cruise docks, and island departures instead of Old Town lanes.
6Babin Kuk
Babin Kuk sits beyond Lapad with larger resorts, Copacabana Beach, forested paths, and more space than the Old Town in peak season.
Getting around
The Old Town is pedestrian-only, so buses, taxis, and airport shuttles stop at gates or nearby roads rather than inside the walls. Libertas buses connect Pile, Ploče, Lapad, Gruz, and Babin Kuk, while ferries from Gruz handle islands and the Old Port handles Lokrum.
