Prague for The Three Generations: a Friday-to-Monday weekend

The astronomical clock's apostles at the hour, the Týn towers and the Hus memorial steps to sit on; a flat square with a bench for everyone.

A lift inside the tower for the grandparents and the ramp around the top for the children, the red roofs and the castle in one turn.

Pilsner has been poured here since 1843; a ground-floor room, long tables, goulash and a children's plate of dumplings, the garden in summer.

Tram 22 to the Pražský hrad stop avoids the steps; the courtyards are flat, the cathedral has a ramp, and the guards change on the hour.

Lunch on the palace terrace at the bottom of the castle, soup and a strudel with the city below, before the funicular-free walk down to the tram.

The baroque garden at the foot of the hill, flat gravel paths, peacocks for the children and a wall of fake stalactites to find faces in.

Seventy-five minutes downstream on a steamer with seats and a bar, under all the bridges to the zoo landing; everyone sits, nobody walks.

A sit-down lunch in Troja between the boat and the château gardens, with Czech dishes on the menu. Reserve a Sunday table for the whole family.

The baroque palace garden next to the zoo, a flat parterre with orange trees, a maze for the children and benches by the fountains.

The island's lawn and the mill wheel on the Čertovka, Černý's crawling babies to climb on, and a bench facing the Charles Bridge arches.

A small modern-art museum in the old mill with a lift to every floor and a terrace over the river; an hour is plenty.

A big pub at street level by the Legion Bridge, roast duck for the table and pancakes for the children, the tram stop outside the door.
