Mirkwood was a dense and heavy woodland that made up much of the eastern portion of Rhovanion or the Wilderland, that maintained its borders and relative shape for many ages. Mirkwood's climate was relatively mild. Except for ways through the thickets of the forest, there were very few commonly used routes through Mirkwood save the Old Forest Road and the Forest Path. Mirkwood was approximately 600 miles long from north to south and 250 miles across from west to east at its width. During the events of The Hobbit it was home to giant spiders, and the kingdom of King Thranduil and his woodland elves; The Woodmen of Mirkwood also inhabited a small part of the forest.
Mirkwood dates back to the earliest days of Middle-earth. The Elves passed through it on their Great Journey from Cuiviénen into the Far West - it was where they made their first long stop before continuing onward. Thereafter, Mirkwood was the dwelling of the Wood-elves (the Nandor, elves descending from the wandering Teleri elf Lenwë) for many thousands of years.

Are you still with me? All of the above was me trying to understand what Mirkwood is. Another caption for an image chosen by Miss @anikarajesh. But this scene in Washington’s Quinault Rainforest scene does match what Mirkwood might have been.
