Island Park Reservoir or Henry's Lake??

[JC_Meridian]

I'm taking an overnight fishing trip this weekend over to the West Yellowstone area. I have never fished anywhere around there, but have always thought the Henry's Lake area looked nice. The park's website says fishing is slow there at the moment though. Island Park Reservoir sounds a little better.

Which would you suggest if camping and bank fishing? I'm more of a warm water guy, but I'll fish for trout too. All tips or suggestions for access and camp sites appreciated.
