The tranquil and beautiful burial spot of David Lloyd George, Prime Minister of the wartime coalition Government from 1916 to 1918 and again prime minister from 1918-22. His grave is only a short walk from a museum dedicated to his life and times. Set on the banks of the River Dwyfor, his last resting place is truly a beautiful spot.

The little road between the A487 at Dolbenmaen in the south and Garndolbenmaen in the north. A high point of about 120m means great views towards the sea in the southwest and up onto the slopes of Craig-y-garn at 340m to the northeast. The road also marks the western boundary of the Snowdonia national Park.
