I think on the website it says that it officially opens at 5 am. So basically plan on getting there while it is still dark. Have all of your stuff ready ahead of time so that you are ready to fish once you arrive. We have found that at Axehead the Berkley trout bait works the best.
I use the Berkley stuff, but I have done very well in the past with nightcrawlers, when the Berkley stuff wasn't working. As with all baits for these trout, use a tiny hook with a small split shot, all under a small bobber/float about 2-3 ft. down. I'd bring both and experiment. Oh, if you do use nightcrawlers, only like a 1-2'' piece is necessary (don't use the whole worm).
