It is not a long hike. The first part is steep and probably muddy. It takes you half way or less to the bottom. The rest of the hike is level across the lava flat along the ocean. It was not bad at all. In fact, although very muddy, my wife and I were very careful and did not mess up our shoes.
At the bottom there is a warning about the danger and the death count for people trying to swim in the pool. We saw some young adults go in and swim. The pool was calm and looked inviting. In a very short time, waves started rolling in and they barely got out alive. Head the warning. Don't raise the count on the warning sign.
15 minutes maybe longer depending on your balance and confidence.
From the car park? 15-20 minutes via the marked path. 5-10 via the shortcut, depending on conditions and your comfort level in climbing very steep paths with ropes.
It was wet, which it almost always is, and it took me 30-45 minutes. The issue is it is so slick that you can’t get any traction and there is very little to hold onto. Hiking poles would have definitely helped. I am not very fit so the fear of falling and breaking something really frustrated me. The teenagers in the group left us way behind.
At a slow pace, the hike to Queens Bath took us about 20 minutes. We took pictures along the way and enjoyed the hike
