Dôl Einion is a small, flat, three-acre campsite set in the southern reaches of Snowdonia National Park, near Tal-y-llyn in Gwynedd.

The site is surrounded on three sides by trees and sits adjacent to the river that feeds Tal-y-llyn lake, with the Cader Idris National Nature Reserve directly next door. It is open year-round and accessible from the B4405 near its junction with the A487.

The site offers grass pitches for tents and motorhomes alongside a limited number of hard-standing pitches with electric hookups. Facilities at the farmhouse include toilets, showers, and drinking water. Dogs are welcome under control.

Dôl Einion provides direct access to the Minffordd Path, one of the principal routes up Cadair Idris, making it a practical base for hillwalkers. An adjacent heritage centre runs a Welsh cultural programme during summer months.
