My first hike of the season always gets me
I'm sorry you are so sore. You could try sitting in an ice bath, although it's best to do it right after you're done with the hike. Also, keeping active helps. I know it's not easy to move around when you're sore, but it really does help and can make the difference between a couple fo days of soreness and several days. I also notice that that the day after I am
less sore than the day after that (does that make sense>), so moving around and keeping your muscles going the day after would help, too.
