Thousand Islands Expeditions

The boat launches from St Davids harbour and within minutes you're among the islands - proper job if you've never seen this stretch of Pembrokeshire coast before. Thousand Islands Expeditions runs trips out to the archipelago that fans across the bay, and depending on the season and conditions, you'll spot seals lounging on rocks, seabirds nesting on the cliffs, and occasionally dolphins if you're lucky enough. The landscape's dramatic - craggy outcrops, caves carved into the sandstone, and water that changes colour depending on the light.

Walkers and wildlife enthusiasts get the most from this. If you're camping at Pembrokeshire Meadows just down the road, it's an easy morning or afternoon excursion that breaks up a holiday nicely without demanding a full day commitment. Kids tend to enjoy the boat ride and the novelty of being out on the water, though they'll need patience for the wildlife spotting.

The trip usually takes a couple of hours depending on the route. You're looking at a bit of money for tickets, but the guides know their stuff and you'll see corners of the coast that are otherwise completely inaccessible. Best in calmer weather - the sea here can kick up quickly. Book ahead rather than turning up, as trips depend on conditions and passenger numbers. If you're staying anywhere within a few miles - Caerfai Bay, Lleithyr Farm, or Rhosson - you're perfectly placed for it. Combines well with walking Pembrokeshire's coastal path sections if you want to mix boat time with solid ground.
