Third Age 3019: The Company, led by Haldir, reach Caras Galadhon by evening.
There was a wide treeless space before them, running in a great circle and bending away on either hand. Beyond it was a deep fosse lost in soft shadow, but the grass upon its brink was green, as if it glowed still in memory of the sun that had gone. Upon the further side there rose to a great height a green wall encircling a green hill thronged with mallorn-trees taller than any they had yet seen in all the land. Their height could not be guessed, but they stood up in the twilight like living towers. In their, many-tiered branches and amid their ever-moving leaves countless lights were gleaming, green and gold and silver. Haldir turned towards the Company.
‘Welcome to Caras Galadhon!’ he said. ‘Here is the city of the Galadhrim where dwell the Lord Celeborn and Galadriel the Lady of Lórien.’

Haldir knocked and spoke, and the gates opened soundlessly; but of guards Frodo could see no sign. The travellers passed within, and the gates shut behind them. They were in a deep lane between the ends of the wall, and passing quickly through it they entered the City of the Trees. No folk could they see, nor hear any feet upon the paths; but there were many voices, about them, and in the air above. Far away up on the hill they could hear the sound of singing falling from on high like soft rain upon leaves.They went along many paths and climbed many stairs, until they came to the high places and saw before them amid a wide lawn a fountain shimmering. It was lit by silver lamps that swung from the boughs of trees, and it fell into a basin of silver, from which a white stream spilled. Upon the south side of the lawn there stood the mightiest of all the trees; its great smooth bole gleamed like grey silk, and up it towered, until its first branches, far above, opened their huge limbs under shadowy clouds of leaves.
