June and September offer the best balance of weather, crowds, and prices. June benefits from the start of the season with pleasant weather and fewer crowds than July-August. September combines autumn colors, mild temperatures (18°C / 64°F), and lower rates. May is also suitable but remains more unpredictable weather-wise. Avoid July-August if you are looking for authenticity, and December-February unless you are on a tight budget.

How many days should I plan for Conwy?

2 to 3 days are enough to discover the essentials: castle, complete ramparts, medieval center, and Plas Mawr. Add a day for Bodnant Gardens and the surroundings (Llandudno, Snowdonia). A long weekend allows you to appreciate the Welsh pace without rushing. History buffs can extend to 4 days by including surrounding castles (Caernarfon, Beaumaris) accessible as day trips.

What to do in Conwy in case of rain?

Rain is not a dealbreaker in Conwy! Visit the covered castle (2h), Plas Mawr (remarkable Tudor house), St. Mary's Church, and authentic historic pubs. The Welsh cultural center offers exhibitions and films. Local art galleries and craft shops are also great options. The Welsh live with 180 days of rain annually: pack a good raincoat and discover the Welsh art of living!

Which events should not be missed in Conwy?

The August Medieval Festival transforms the town into an exceptional living spectacle in an authentic UNESCO setting. The September Classical Music Festival offers intimate concerts in heritage sites usually closed to the public. The Welsh Christmas market (December) creates a magical atmosphere despite the cold. In summer, the July regattas bring the marina to life. Check the local calendar as many small events enrich every season.

What budget should I plan for based on the season?

Winter: €80-€130/day (accommodation €45-€70, meals €25-€40). Spring/Autumn: €100-€160/day (accommodation €55-€90, meals €30-€45). Summer: €140-€230/day (accommodation €85-€140, meals €35-€55). Add €25-€50 for attractions depending on the season. Welsh B&Bs offer excellent value for money. The Cadw heritage pass (£30) pays for itself after 3 sites.
