Stand-up paddleboarding has taken off on Anglesey, and it’s easy to see why: the island has sheltered bays of clear water, dramatic coastline to explore at sea level, and just enough tidal drama to keep you respectful. But this is a real coast with real currents — so this guide covers both the best spots and the safety that keeps a good day from turning into a rescue.
Best paddleboarding spots
Trearddur Bay — the sheltered all-rounder
Trearddur Bay on Holy Island (Ynys Gybi) is the standout for most paddlers. The horseshoe shape shelters it from the prevailing westerly wind, the water is clear and often calm, and the rocky headlands at either end are fun to explore on a settled day. It’s the most beginner-friendly launch on the island when conditions are kind.
Red Wharf Bay — vast and shallow
When the tide is in, Red Wharf Bay (Traeth Coch) on the east coast becomes a huge, shallow, sheltered expanse — good for relaxed flat-water paddling with the Ship Inn waiting at the end. The catch is the tide: this bay empties to far-out sand, so you must paddle on a rising or high tide and get off before it drains.
Rhosneigr — for when there’s a bit of swell
Rhosneigr on the west coast has lagoons and inlets that suit paddling, but it faces the open Atlantic, so it’s better for confident paddlers or for SUP surfing on a small day. The watersports village has the gear and lessons to match.
Llanddwyn and Newborough
The water off Newborough Beach toward Llanddwyn Island is a memorable paddle on a calm, settled day — but it’s exposed and tidal, so it’s one for experienced paddlers who’ve checked conditions carefully.
Lessons and hire
If you’re new, take a lesson rather than winging it. Holy Island and Rhosneigr have watersports operators who run SUP sessions and hire boards — the same west-coast scene that supports surfing and kitesurfing. A guided session also teaches you to read the local conditions, which is the part that actually keeps you safe.
Safety: the part that matters
The Menai Strait and several Anglesey bays have strong tidal currents — paddleboarders get into trouble here every season. Take this seriously:
- Never paddle the Menai Strait without local knowledge. The tidal flow through the Strait, and especially the Swellies between the bridges, is fierce and dangerous. Leave it to guided trips and experienced sea paddlers.
- Always wear a leash and a buoyancy aid. A board blows away from you faster than you can swim after it.
- Check wind and tide before every session. An offshore wind will carry you out to sea — if the wind is blowing from the land toward the water, don’t go out. Paddle into the wind first so the return leg is with it.
- Tell someone your plan and carry a means of calling for help in a waterproof pouch. In an emergency, call 999 and ask for the Coastguard.
- Start small and sheltered. Build up on calm days in Trearddur or Red Wharf before going near the open coast.
Pick a sheltered bay, watch the wind and the tide, wear your leash and buoyancy aid, and Anglesey’s clear water is a fine place to learn. For more on getting into the sea here, our wild swimming guide shares the same safety mindset.
