Plenty of people see Anglesey as a day trip — staying in Llandudno, Betws-y-Coed, or somewhere in Eryri (Snowdonia) and crossing the Menai Strait for the day. It works well, because the island’s headline sights cluster near the bridges. The key is not trying to do too much: Anglesey’s rural lanes are slow (reckon 8 miles to 20 minutes off the main roads), so a realistic day picks two or three places, not ten. Here’s how to make the most of one day.
Getting onto the island
From Llandudno, Bangor, or the A55, you cross to Anglesey over the Britannia Bridge or the older Menai Suspension Bridge at Porthaethwy (Menai Bridge). It’s quick — around 30–45 minutes from Llandudno, less from Bangor. Both bridges land near Menai Bridge town, which makes the southeast corner the natural focus for a day trip. For the full set of routes, see how to get to Anglesey.
A classic day-trip plan (southeast)
This is the easy, low-driving version that suits a first visit.
Morning — Beaumaris. Cross the bridge and drive 10 minutes to Beaumaris (Biwmares). Spend the morning at the UNESCO Beaumaris Castle and walking the Georgian seafront, with the mountains you’ve just left framed across the water. If the timing suits, a Puffin Island boat trip from the pier adds seals and seabirds (book ahead).
Lunch. Eat on the Beaumaris seafront — the town has a strong run of pubs and restaurants. Allow a proper hour; you’re on holiday.
Afternoon — the photo stops. On the way back, pull in at the famous railway station with the longest name in Britain, Llanfairpwllgwyngyll… (mercifully shortened to Llanfairpwll or Llanfair PG) for the obligatory sign photo. If there’s time and energy, carry on to Bryn Celli Ddu, a 5,000-year-old Neolithic passage tomb in the fields nearby — free, atmospheric, and a complete change of pace.
The beach-day alternative (southwest)
If you’d rather have sand than castles, swap the above for a single bigger drive: head to Newborough Beach (about 25–30 minutes from the bridge) for a mile of firm sand, red squirrels in the pine forest, and the walk out to tidal Llanddwyn Island with its white lighthouse. Check the tide times, bring a picnic, and you could happily spend the whole day here.
Tips for a day trip
- Pick a corner and stick to it. Don’t try to cross the whole island and back — the lanes will eat your day. The southeast (Beaumaris) or southwest (Newborough) are the two best day-trip zones from the bridges.
- Book boat trips ahead in summer; they sell out.
- Check tide times if Llanddwyn is on your list.
- Leave a buffer for the A55 at peak times and on summer weekends, especially near the ferry port at Holyhead.
- Want more than a day? It’s worth staying over — see where to stay on Anglesey and our full weekend itinerary.
One day is enough to fall for Anglesey — just don’t spend it all driving. Choose a corner, take it slowly, and you’ll be planning the return trip before you’ve recrossed the bridge.
