01. Llynnau Cerrig-y-Myllt
Good for:
Open water swim or a quick dip
Day hike with a swim
Golden hour
Mountain views
About: This stunning lake offers a secluded spot for a golden hour dip. Off the beaten track but accessible via a short uphill walk, it promises tranquility and natural beauty, making it the perfect mountain dip.
How to get to Llynnau Cerrig-y-Myllt: While many start from the small village of Beddgelert, we chose a shorter route beginning at Nantmor Mountain Centre. Just past the centre, there is a small, free parking area. The walk to the lake took us about an hour, and along the way, you'll pass another beautiful lake (Llyn yr Arddu). Despite having to fend off a few midges, the effort was well worth it for the golden glow of the setting sun!

Family friendly area
Stones throw from carpark or circular walk
Paddle board / Kayak friendly
About: Llyn Geirionydd is a hidden gem within Snowdonia National Park and is the perfect place to for a quick dip or open water swim. The shoreline is very accessible and close to the parking – you can swim, kayak and paddle board on the lake and there is a circular walk around the lake where you will find a couple of more secluded swim spots over the other side.
How to get to Llyn Geirionydd: There is car park at the southeastern end of the lake. It’s free to park and there are picnic areas, toilets and baby changing facilities. From the car park, you can set off in either direction around the lake. The trail is wide and way-marked all the way through. On the eastern side of the lake, it’s a broad country lane; on the western side, a public footpath. We chose to do our swim round the other side of the lake where it was very quiet (we only saw one other couple whilst walking).

Things to note: The road to get there is pretty narrow in places and very windy and steep. We were in our Vauxhaul Vivaro van and found it manageable but you might want to double check if you have a motorhome before you go. Overnight parking is not permitted.

Good for:
Plunge pools
Quick dip
Day hike with a swim
Mountain views
About: The Watkin Path is one of the routes you can take to reach the summit of Mount Snowdon, the highest peak in Wales. It’s typically one of the tougher and therefore less crowded ways to hike up Snowdon however it’s stunning waterfalls and blue plunge pools do attract the crowds in good weather so if you want them to yourself, like us, be sure to get up early!
How to get to Watkin Path Waterfalls: Park at Pont Bethania car park (£6 per day or £3 for up to four hours and also has toilets). There is also a free parking option in a spacious layby nearby, though it's worth noting that these spots tend to fill up quickly, particularly on a nice day. The Watkin path starts across the road at the stone staircase. Simply follow the Watkin Path up the hill through the woods and, after about 20 to 30 minutes walking, you'll see the waterfalls in front of you.

Things to note: We had no phone signal in the area, which on previous trips has made it challenging to meet friends in the area. So be sure to communicate your plans of meeting up before you get to the area! If you are going to the summit, always plan ahead, check the weather, wear appropriate footwear and take a map.
06. Aberglaslyn
Good for:
Quick dip
Plunge pools
Short walk with a picnic
About: The picturesque Glaslyn river flows through the stunning landscape of Snowdonia National Park, including the serene Llyn Gwynant and Llyn Dinas, before emptying into Tremadog Bay. There are beautiful wooded walks along the gorge if you wish to spend more time in the area.
How to get to Aberglaslyn: There’s a small National Trust car park about a 5-minute drive from the centre of Beddgelert. The river runs alongside the road, and there is a bridge nearby. The parking fee is about £5, or free for National Trust members, though the machine was broken when we visited. There are also toilets available in the car park.
Several swim spots can be found in the area. The first one is accessible by turning right out of the car park and looking for a steep path down to the river just over the stone wall. Since this spot already had a few people enjoying it, we decided to head back up to the road, cross the bridge, and go down the other side. Here, we discovered a more secluded spot with a small shingle beach and a plunge pool. Both swim spots are about a 5-minute walk from the car park.

There is a small tidal pool that’s perfect for little ones to have a splash about in too.
How to get to Porth Iago beach and where to stay: You can only access the beach via the water (if you are paddling from elsewhere) or through the small campsite located on the cliff above the beach. It offers basic facilities for campers, including toilets and showers and has a small kiosk offering drinks and ice creams. In June 2023 it cost us £21 per night (plus £2.50 for a dog), you pay machine at the farm on the way to carpark. You don’t have to stay at the campsite to visit the beach but you will have to pay a parking fee for the day. We’ve been a couple of times and it’s always been nice and relaxed!

09. Ceunant Llennyrch
Good for:
Waterfall swim
Short walk
Easy entry point
Picnic spot
About: Ceunant Llennyrch is a stunning and secluded gorge located near Maentwrog in North Wales, within the Snowdonia National Park. This area is renowned for its dramatic landscapes, ancient woodland, and cascading waterfalls. Due to its relatively remote location, Ceunant Llennyrch remains a peaceful retreat, providing an escape from the hustle and bustle of more popular tourist destinations.
How to get to Afon Prysor: From Maentwrog, take the A496 road to Harlech. After you pass the Maentwrog power station entrance on your left, look for the main woodland entrance on the same side of the road just after crossing a bridge. Alternatively, approach Llennyrch from the dam at Trawsfynydd.
The main entrance is at the lower end of the woodland where there is a free small parking. From here you go through the gate and the footpath loop follows the valley of the Ceunant Llennyrch, starting fairly wide and level but becoming steeper as it rises towards the waterfall at the eastern end of the wood.

Lyn Cau is one of the highlights of hiking Cadair Idris. The glacial lake is situated in a dramatic hollow on the eastern side of the mountain. The lake is surrounded by steep cliffs and is great for a swim in!

The most popular routes include the Minffordd Path, the Pony Path, and the Fox's Path. Each route offers its own challenges and rewards, and all of them provide breathtaking views along the way. We parked at the Dôl Idris Car Park (£4 for 3 hours, or £6 for all-day parking).
