Elidir Fawr Walk
Climb to Elidir Fawr, the northernmost peak in the Glyderau range on this challenging walk in Snowdonia. The walk takes you to the 924 metre (3,031 ft) summit from the village of Nant Peris at the bottom of the Llanberis Pass. It's only about a 2 mile climb, but quite steep.
The walk starts from the parking areas off the A4086 in Nant Peris. Cross the A4086 and then pick up a country lane heading north. A footpath then takes you the rest of the way to the summit, passing the Afon Dudodyn on the way. There are fabulous views over the peaks and reservoirs of the national park.
You can extend the walk by continuing a short way on to the pretty Marchlyn Mawr reservoir.
Following the path further will take you to Foel-Goch and then on to Y Garn. From the 947 m (3,107 ft) summit there are great views of Llyn Clyd and the Ogwen Valley.
Also nearby are the climbs to Glyder Fawr and Glyder Fach and Tryfan.

For an alternative circular walk from the Marchlyn Mawr Reservoir see the video below.
If you head north west from the car park you can enjoy a waterside walk along Llyn Peris.
Padarn Country Park is also nearby. You can pick up the Llanberis Lake Walk and the Dinorwic Quarry Walk here. The quarry is one of the significant sites on the Snowdonia Slate Trail which runs through the area. The circular long distance trail can be used to visit several of the other historic mining areas located in the World Heritage Site. Heading north along the trail would take you to Bethesda where you could visit the Penrhyn Quarry which was the largest slate quarry in the world during the 19th century. Heading south along the trail would take you to Dorothea Quarry where you'll find the remains of the old mining houses and a series of scenic lakes including Llyn Nantlle Uchaf.
