Vilnius

A 14th-century red-brick tower on Gediminas Hill, the national symbol. The interior museum and the funicular are closed to non-assistance pets, but the switchback path to the summit is leash-friendly and offers one of Central Europe's best free panoramas.

Historic Renaissance garden on the right bank of the Vilnia stream, with rose garden, lime tree alleys, and the famous bronze statue of three Lithuanian Hounds. Open daily, leashed dogs welcome.

Vilnius's largest park (160 hectares) on a bend of the Neris, with pine forest, an open-air amphitheatre, and a marked dog beach. Off-leash tolerated on the beach and the wooded inner trails; trolleybus 7 from the Cathedral.

Bohemian artists' quarter that declared itself an independent republic in 1997, separated from the Old Town by the Vilnia stream. Constitution wall, the Angel of Užupis statue, and dozens of dog-friendly cafés — the city's most pet-welcoming neighbourhood.

Iconic monument of three white crosses on a wooded hilltop east of the Old Town, in Kalnų Park. The climb from Bernardine Garden is leash-friendly, about 25 minutes — the second-best free panorama in Vilnius.

Red-brick island castle on Lake Galvė, 30 km from Vilnius by train. Leashed dogs are welcome on the lakeside path and the wooded peninsulas; the castle itself is closed to non-assistance pets.
