St Tudwals Island East

You'll need a boat to reach this one, which immediately sorts the casual day-trippers from those actually keen on the effort. St Tudwal's Island East sits off the Pwllheli coast in Gwynedd, a proper little rocky outcrop crowned with the remains of an ancient chapel and offering views across Cardigan Bay that'll make you forget the slightly chaotic crossing. The island itself is small - you're not talking hours here, more like forty minutes to an hour of wandering, climbing over rocks, and poking around the ruins if history's your thing. Walkers and photographers get the most from it; families with young kids might find the boat ride the highlight. The real win is combining this with a stay at one of the nearby parks. Tal-y-Fan or NightSky Glamping sit within easy striking distance, and the contrast between island adventure and a comfortable evening back on the mainland works well. Spring through early autumn is obviously better weather-wise, though even in decent winter sun the light across the water can be striking. You'll want to check tide times and local boat operators from Pwllheli before planning a trip - it's not the kind of place with set schedules. Admission to the island itself is typically free once you've sorted your passage across, but factor in boat costs and the fact it's genuinely only worth doing if you're already based nearby for a few days. It's a brilliant add-on for a park holiday, not a standalone reason to visit the area.
