Whether you have a few hours or a full weekend to explore, these itineraries give you a local’s route through Caernarfon. Each one links directly to the restaurants and activities along the way.
Half a day from Y Maes: the castle, round the walls, and up to the Romans
The castle, the walls and the Roman fort a thousand years older, a lunch inside the walls and a drink on the harbour, all on foot from Y Maes. The castle opens at 9:30 for most of the year and 10:00 in winter, per Cadw. Segontium's access is uneven, so ring Cadw before step 4.

Caernarfon Castle
Straight in at opening, ticket bought online for 5 per cent off or at the desk. On days Cadw runs them, a custodian tour leaves at 11:00 for £5 extra.

Round the walls from below
Free and ticketless. Cadw has the ramparts closed, so take the loop out to the harbour, through Porth yr Aur and back by Northgate Street and Porth Mawr.

Lunch at the Black Boy
Walk-in only, with a list at the door, so go early rather than late.
View Black Boy Inn - 414:00·45 minutes
Segontium
About 700 metres up from Y Maes on Constantine Road. Cadw's page says both 'open all year' and 'selected tour dates May to August', so check before you walk up.

A drink by the water
Back down to the Anglesey, the old Customs House against the outside of the wall, facing the Menai Strait.

A full day: steam to Beddgelert, and the castle after
The Welsh Highland Railway's Gelert Explorer leaves Caernarfon at 11:10 and is back at 15:25, which leaves the morning for Cei Llechi on the quay and the late afternoon for the castle, open until 5pm for most of the season. Check the railway's running days first; it is a seasonal timetable.
