(1)

The best things in life are the people you meet, the places you’ve been and the memories you’ve made along the way…. so make yours a trip to remember at Ty Gwyn, the Big House by the sea! Ty Gwyn – which sleeps up to 30 - overlooks Llwyngwril (pronounced hlwin-goo-ril), a beautiful coastal village situated on the stunning coast of north-west Wales just south of Barmouth. It’s perfect for big famil

y parties, special occasions and retreats. If you’re an adrenaline junkie then Ty Gwyn is the place for you, with water sports, mountain biking trails and the fastest zip line in the world all on your doorstep. If you’re looking for peace and tranquility then there are beautiful walks by the beach, and in the nearby mountains and forests of the Snowdonia National Park. Does even that sounds like too much effort? If so Ty Gwyn has its own sauna, hot tub and cinema. We recommend you enjoy a lovely meal together, toast marshmallows on the large open-air fire pit, and let the real world just float away as you watch the amazing sunset.

Portmeirion is a much-loved Italianate village in the very heart of Eryri. Escape to the village for dreamy architecture and gorgeous views! 🏔️

Go via the train or, take a drive if you brought the car (psst, it's a local secret that if you do, it's quicker and more scenic to take the Penmaenpool Toll Bridge.)

We're just a hop and a skip away so, why not gather the whole family this summer? https://www.bighousebythesea.com/availability/

Off for a Weekly Wander? So are we-

Our favourite would have to be the Mawddach trail! It's a stunning multi-use path following the old disused railway line along the edge of the beautiful Mawddach. So if you fancy seeing the true beauty that Eryri has to offer, set off for a stroll during your visit 👣

What are our top 5 favourite spots to visit in and around Llwyngwril? Well-

𝐂𝐚𝐝𝐚𝐢𝐫 𝐈𝐝𝐫𝐢𝐬! ⛰️
One of the best walks in Wales, in our opinion! Better than Yr Wyddfa too as it's normally far less crowded and easier to park! Hike the whole mountain or simply to the lake with a picnic.

𝐏𝐨𝐫𝐭𝐦𝐞𝐢𝐫𝐢𝐨𝐧 🏘️
A much loved Italianate village on the shores of the Mawddach - catch an ice cream or take a stroll through this Welsh wonder.

𝐅𝐟𝐞𝐬𝐭𝐢𝐧𝐢𝐨𝐠 𝐑𝐚𝐢𝐥𝐰𝐚𝐲 🚂
Take a steam train through the beauty of Eryri - hop on at Blaenau Ffestiniog and head up to Porthmadog, then back again!

𝐙𝐢𝐩 𝐖𝐨𝐫𝐥𝐝 🪂
If you have a head for heights, why not take on the fastest zip line in the world?

𝐓𝐡𝐞 𝐁𝐞𝐚𝐜𝐡! 🏖️
The Cambrian Coast is world renowned for its beauty, so why not hop on the train or take a drive to one of its many stunning beaches. Barmouth, Aberdyfi, Fairbourne and even Llwyngwril a short walk away, are at your fingertips! Perfect in this stunning weather!
