North Wales & Eryri
Choose a castle coast or mountain gateway; the same train does not finish both days.
Conwy and Llandudno, Eryri’s mountain gateways, and Caernarfon with Anglesey form three distinct North Wales systems. Rail follows the coast, while mountain routes and castles add buses, seasonal railways, parking and weather. One named gateway per day is the practical standard.
Choose one file from the gateway, weather and return you actually have.
Every file carries its own access decision, sequence, fallback, break points, official sources and licensed image record.
Conwy Castle & Llandudno
Choose Conwy’s castle-and-walls or Llandudno’s bay-and-Great-Orme system as the main day, using the short rail link once instead of repeatedly crossing the coast corridor.

Yr Wyddfa Gateway Choice
Choose a specific Yr Wyddfa route or mountain railway product from its real gateway, matching ability, parking or bus access and summit weather rather than treating every path as one attraction.

Caernarfon & Anglesey
Choose Caernarfon Castle or one Anglesey coast community as the main destination and make the Menai crossing and onward bus or road explicit.

Conwy Castle & Llandudno
Gateway: Conwy station is small and close to the walls; Llandudno and Llandudno Junction are different stations. Great Orme attractions start beyond the main station. Choose the town order and final rail station before entering the castle or headland.
Sacrifice: A deep castle, full walls and Great Orme circuit exceed one relaxed day. Choosing Conwy sacrifices headland depth; choosing Llandudno gives up some medieval interpretation.
Time: Allow a full day for one deep town plus a short second stop. Conwy or Llandudno alone needs five to seven hours.
Yr Wyddfa Gateway Choice
Gateway: Yr Wyddfa has multiple trailheads on different roads. Parking, Sherpa’r Wyddfa buses and Llanberis services vary by date. The mountain railway has its own station, booking and operating limits. Confirm the exact start and final return before travel.
Sacrifice: A summit walk and mountain railway are separate products, not backup versions of the same day. Choosing the summit sacrifices village and museum time; choosing lower Llanberis gives up the top but preserves safety and transport.
Time: Allow the full day for a summit walk or railway-and-Llanberis plan. Lower village and lake routes can fit five to seven hours.
Caernarfon & Anglesey
Gateway: Caernarfon has no mainline rail station and is reached by bus or heritage railway. Anglesey has a rail line but many beaches and villages lie beyond stations. The Menai bridges carry road and bus traffic; select the exact island endpoint before crossing.
Sacrifice: A deep castle visit and a meaningful west Anglesey coast day are separate plans. Choosing the island sacrifices Caernarfon depth; choosing the castle gives up a distant beach but protects a coherent return.
Time: Allow a full day for Caernarfon plus one nearby Menai branch, or a separate full day for west Anglesey. The castle town alone needs four to six hours.

North Wales & Eryri FAQ
How long should I give North Wales & Eryri?
Four to six nights supports a coast town, one Eryri day and a western castle or island branch. Llandudno Junction is useful for rail; Betws-y-Coed, Llanberis and Caernarfon open different mountain approaches and are not interchangeable bases.
What transport decision matters most around North Wales & Eryri?
Transport for Wales serves the north coast and Conwy Valley; buses and heritage railways continue to mountain gateways. Yr Wyddfa routes start from different points. Anglesey road and rail access does not automatically reach every coast site.
What should I do if weather, access or transport changes?
Use Conwy, Llandudno, Caernarfon or a rail-valley town when mountain access fails. Do not replace a closed Yr Wyddfa route with another high summit without a new forecast and transport plan.
