Tresaith Waterfall: Guide to Wales’s Only Beach Waterfall (Ceredigion)
Tresaith Waterfall is one of the most unusual and photogenic natural features in Wales — a waterfall that falls directly onto a beach, created where the River Saith descends over the cliff at Tresaith Beach in Ceredigion, south-west Wales. It is the only waterfall in Wales that flows directly onto a sandy beach, making it a genuinely rare sight and one of the most distinctive coastal spots in the country.
This guide covers everything you need to visit Tresaith Waterfall: how to get there, parking, the walk to the waterfall, the best time to visit, what to do at the beach, and nearby attractions worth combining with your trip.

Where Is Tresaith Waterfall?
Tresaith Waterfall is located on Tresaith Beach in Ceredigion, a small and quiet beach village on Cardigan Bay between Llangrannog (to the north) and Cardigan (to the south). Despite sometimes appearing in guides to Pembrokeshire waterfalls, Tresaith is technically in Ceredigion — the county immediately north of Pembrokeshire. The waterfall is formed where the River Saith reaches the end of its course and drops over the coastal cliff directly onto the sand.
The village of Tresaith itself is very small — a pub, a car park, and a handful of cottages and holiday properties clustered above the beach. Its remoteness is part of the appeal.
How to Get to Tresaith
By Car from the North
Take the A487 south. Just before the village of Tan-y-Groes, take the right turn onto an unclassified road signposted for Tresaith. Bear left at the junction which brings you into the village. The car park is on your left near the bus stop.
By Car from the West (Cardigan)
Head for Cardigan, then take the A487 north towards Aberystwyth. Just after the village of Tan-y-Groes, take the left turn towards Tresaith and follow the directions above into the village.
By Car from the South and East
Head for Carmarthen on the A483/A40. From Carmarthen take the A484 to Cynwyl Elfed, then the B4333 to Newcastle Emlyn. Continue north on the B4333 until the junction with the A487. Turn right onto the A487 and take the left turn signposted Tresaith just after Tan-y-Groes.
Note: The roads approaching Tresaith are narrow single-track lanes for the final stretch. Drive slowly and be prepared to reverse into passing places for oncoming vehicles. This is particularly relevant in summer when visitor numbers increase significantly.
Parking at Tresaith
The car park at Tresaith is on the left-hand side of the road near the bus stop as you enter the village. It is a small car park — arriving early on summer weekends and bank holidays is advisable, as it fills quickly. Payment is via an honesty box; verify the current charge on arrival as it may vary.
There is no overflow parking near the village. If the main car park is full, you will need to wait for a space or park further up the lane and walk down. Summer Saturday afternoons tend to be the busiest times.

The Walk to Tresaith Waterfall
The walk from the car park to the waterfall is short and straightforward:
Step 1: From the car park, locate the long flight of steps to the right-hand side of the bus stop. Take these steps down to the bottom.
Step 2: At the bottom of the steps, turn left towards the slipway. As you walk, you will pass a café and shop on your right and the public conveniences (with wheelchair access) on your left.
Step 3: Beach access is on your right. As you emerge onto the beach, look to your right towards the rocks at the right-hand end of the beach (as you face the sea). The waterfall is visible from the sand, cascading down the cliff face.
Step 4: Walk across the sand to the right-hand end of the beach. If the tide is low enough, you can walk across the sand directly to the waterfall. If you want to get closer, it is possible to clamber over the rocks at the base of the cliff — there are convenient flat rocks to sit on with views of both the waterfall and the sea.
The entire walk from the car park to the waterfall takes approximately 10 minutes.
Tides and Best Time to Visit
Tresaith Waterfall can be seen from the beach at virtually any state of the tide, but low tide provides the best access and the most dramatic views. At high tide, the waterfall may fall directly into the sea, which is impressive in its own way but limits how close you can get on foot.
If you want to cross below the waterfall to the smaller beach beyond, this is only possible at low tide. Be aware that it is possible to become cut off on the far side of the waterfall if the tide comes in while you are there — check tide times before visiting and do not attempt to cross to the second beach on an incoming tide.
Tide tables for Cardigan Bay are available from the Met Office and from several coastal weather apps. Visiting 1 to 2 hours either side of low water gives the best combination of access and photography conditions.
On a sunny day, the waterfall can produce a rainbow in its spray — one of the most photographed effects at Tresaith. Morning visits tend to produce better light for photography on clear days, as the sun is more likely to be positioned to create spray rainbows.
What to See and Do at Tresaith
The Waterfall
The waterfall itself is Tresaith’s primary attraction — the River Saith descending over the cliff and falling directly onto the beach below. At full flow after rainfall, the waterfall is powerful and audible from the beach. The spray at the base creates a cooling mist on warm days and, in sunlight, the characteristic rainbow that Tresaith is known for photographically.
The rock platform at the base of the cliff below the waterfall is accessible at low tide and provides the closest viewpoint. The rock surface can be slippery with sea spray and algae — wear footwear with grip rather than flip-flops or bare feet if you intend to scramble to the base.
Tresaith Beach
Tresaith Beach holds Blue Flag status — a recognition of water quality and facilities that places it among the cleanest beaches in Wales. The beach itself is a small, sheltered sandy cove with rock pools at low tide. It is significantly less crowded than more well-known Ceredigion and Pembrokeshire beaches, partly due to the limited parking.
The beach is suitable for swimming in calm conditions. The pub (The Ship Inn) is within walking distance at the top of the steps. The café and shop near the beach access are open in season.
The Second Beach
A smaller, more secluded beach can be reached by crossing below the waterfall at low tide. This requires careful timing — only attempt the crossing on an outgoing or low tide, and be back before the sea returns. The second beach is almost always quieter than the main beach and offers a sense of seclusion that is difficult to find on the Welsh coast in summer.
Wildlife — Dolphins and Seals
Cardigan Bay is one of the best places in the UK to spot Atlantic bottlenose dolphins and grey seals in the wild. The bay holds the largest resident population of bottlenose dolphins in the UK. Dolphins can sometimes be spotted from the beach or cliff tops at Tresaith, particularly in summer months when they follow shoals of fish close inshore. Grey seals are also commonly seen on and around the beaches and rocky outcrops of this stretch of coast.
For the best wildlife spotting, arrive early in the morning before the beaches fill up and watch the water patiently. The Cardigan Bay Marine Wildlife Centre in New Quay (approximately 12 miles north) provides information on dolphin populations and organises boat trips.

Nearby Attractions to Combine with a Tresaith Visit
- Llangrannog: A beautiful village beach approximately 3 miles north of Tresaith, with a dramatic cliff setting and the option to walk the coast path between the two villages. One of the most attractive beaches in Ceredigion.
- Mwnt Beach: A secluded cove approximately 5 miles south, one of the most beautiful and least-developed beaches in west Wales, with a tiny whitewashed church on the headland above. Excellent for grey seal spotting.
- Cardigan (Aberteifi): The nearest market town, approximately 10 miles south, with Cardigan Castle (a recently restored medieval castle) and good independent shops and cafés.
- New Quay: Approximately 12 miles north — the best base for dolphin-watching in Cardigan Bay, with regular boat trips and the Cardigan Bay Marine Wildlife Centre.
- Cenarth Falls: An impressive waterfall on the River Teifi approximately 10 miles inland, with a coracle museum and National Nature Reserve. A good inland complement to the coastal Tresaith visit.
Practical Tips for Visiting Tresaith Waterfall
- Arrive early: The car park is small and fills quickly on summer weekends. Aim to arrive before 10am on busy days.
- Check tide times: Low tide provides the best access. The Met Office tide forecast for Cardigan Bay is available free online.
- Wear appropriate footwear: The rocks at the base of the waterfall are slippery. Trainers or walking shoes are better than sandals or bare feet.
- Be aware of the second beach tide risk: Only cross to the second beach beyond the waterfall on a low or outgoing tide. The crossing can be blocked quickly on an incoming tide.
- Photography: Bring a polarising filter if shooting with a camera — it helps with the waterfall mist. Morning light and sunny days produce the best rainbow effects.
- Dolphin watching: Bring binoculars and scan the sea from the beach or cliff tops, especially early morning.

Final Thoughts
Tresaith Waterfall is one of Wales’s genuinely unique natural attractions — a beach waterfall with no equivalent elsewhere in the country. The combination of the waterfall, the Blue Flag beach, the relative seclusion compared to better-known Ceredigion and Pembrokeshire beaches, and the wildlife opportunities in Cardigan Bay make it a visit that rewards the effort of navigating the narrow approach roads.
If you are visiting Pembrokeshire or Ceredigion, Tresaith is well worth the short diversion north of the Pembrokeshire border. Allow at least two hours to explore the beach and waterfall properly, ideally timed around low tide for the best access. The combination of Tresaith with Llangrannog or Mwnt makes a full day of some of the finest coastal scenery in Wales.
