i just hiked that trail two weeks ago.
unfortunately, it was spring break for the local high schools so the trail was fairly crowded.
the springs were cool though; once you hit the big sur river, you cross it and turn left. wade thru the creek and then cross back over and stay to the west side (you have to do this unless you want to cross a steep cliff face area). then there are three pools about a 1/4 mile down. they are fairly small but i had one to myself where i soaked for about 20 mins.
there were about 20-30 people camped in the area, so i bailed and headed back to a site that was just above the first creek you cross. i had that area to myself. i hiked out the next morning.
the trail conditions are good. it felt like summer at the beginning of the hike. hot and dusty, with lots of blossoming lupine and shooting stars, but poison oak as well. that first bit is south facing so that explains the summer-like conditions. thereafter, its normal ventana hiking.
josh, mike, and i did the ridge trail from china camp at the beginning of march-- that area is much more rugged, weith trail conditions a bit sketchy with lots and lots of downed trees and even snow (thats probabaly melted by now).
i like the vicente flat hike. its farther south than julia pfeiffer SP but some cool redwood stands and springs at the camp-- neat fact-- these are the lowest coastal redwoods in the world.
