Has anyone drove the road from I-80 north to Jackson and on in to Yellowstone? I think its just a two lane highway?
That whole stretch of river right around your campground is good. I spent quite a bit of time up the Lamar Valley last summer. It would be worth the drive to hit Trout Lake, it was full of big fish. Good chance you could have it to yourself - we did in mid July last summer.http://www.greater-yellowstone.com/Yellowstone-Park/Trout-Lake.htmlAs an additional benefit, the Lamar Valley is the best place to see critters in the whole Park. I've been in and out of each entrance and pretty much everywhere in between (Grand Teton as well), and the Lamar Valley is hands down the best place for animal watching. The Lamar River itself can be great fishing, but it was pretty high and colored up when we were there last July.
There are nice fish right at the campground. I caught some 14" Browns while a bunch of kids were swimming and skipping rocks just yards away. The Firehole dumps in across the river from the campground. Depending on flows you should be able to wade across the Madison and Fish up the Firehole a good way. If you go to the Lamar Valley check out Soda Butte Cr. Similar to Slough but easier access.
So does anyone have advice for fishing near Canyon Campground? I'll be there in July.
