Park at Fern Canyon and walk through Fern Canyon to Fern Canyon Trail, James Irvine Trail, and Clintonia and Miner’s Ridge Trails.
Fern Canyon was one of the filming locations of Jurassic Park and the rest of the state park has stunning old growth redwood groves.
I too love the redwoods. I used to ride my bike all around Kings Mountain and Tunitas Creek and many other roads and just loved the experience.
When people visit I would always take them to Big Basin or Muir Woods vs. the other usual suspects.
Maybe they were just suffering from the uphill?
And I went to big basin when it was reopened, and it was a little tragic. So many enormous, but black trunks.
You can see a lot of the green growth starting around the trunks (shown in the article pictures), but it might not look lush and green again in your lifetime.
That said, there is a lot of explosive growth of flowers in the santa cruz mountains (watch out for the white poison oak flowers)

AllTrails also reports that it's closed (as do others).

If you want a similar experience now, your best bet is to head north on 101 into the Redwoods State and National Parks system, visit places like Avenue of the Giants and Women's Club Grove. All north of Garberville. Spots along the road will all be crowded from now through September, but if you do some exploring of your own, you can still find some nice quiet places full of enormous trees.
