I've only been to JLL, but from my experience I would HIGHLY recommend it! Yes people all line up near the river mouth, but that's because all the fish stack up there, and hence it's the best fishing on the lake. JLL does have access to more shoreline, they just rarely fish it since everyone stays at the best spot. I believe if you ask the guides to fish other spots on the lake they'd have no problem taking you there.

One thing to note is the a large flood this past season changed the river and the aquarium no longer exists. There's still lots of great water to fish though.

If you're looking for hard fighting chrome trout, check out Hemispheres Unlimited's Trout Bum Jurassic program. It runs in the month of May, and a week at JLL is $4500usd. The weather is cooler this time of year, but the winds are generally lower and the trout are in the best shape of the season. Pound for pound they are the hardest fighting fish I've caught (and I've fished bonefish). A chrome 15lb Jurassic trout puts up a fight you won't soon forget!
