I've found it best to go down the night before, make the trek from the parking lot to the hole and stake out a fishing spot. Be sure to pack along enough patience for three days. With the numbers of anglers, it's best to enjoy what you can. You'll also need to take enough tackle to last the day as you won't want to give up your spot once you've dug yourself in. It's also a good idea to take along lots of food.
Anglers do get hungry.
Once you've arrived at the Blue Creek Hole, you'll have to devise a way to keep other anglers far enough away from you so you can make a cast. Several things have been tried like explaining to the anglers on either side of you that your gym teacher in high school always said stay an arm's length away while doing jumping jacks. There's a safety factor involved here. The same goes for steelheading. I hate to paint an ugly picture of the Blue Creek hole, but it can be quite crowded.
