Re: Yellowstone Fishing Guides
In the Gardiner area, check with Walter Weise at Parks Fly Shop. If you are paying for a guide, for myself, I would probably want the full day trip versus the half day. Lots of nice water, scenery, and good fishing in the Yellowstone River that time of year. Hopefully the hoppers will be back to normal this year - they were pretty scarce last summer.
In West Yellowstone, check with Craig Matthews at the Blue Ribbon Fly Shop. There might be others there, as already mentioned, that are as good, but you' d be hard pressed to find anyone that is better.
Snowpack looks very good in the Yellowstone region as of now, and unless there is some early melting, that bodes well for the water levels and fishing this coming summer. I'm sure you will enjoy your trip.
P.S. During the summer, I'm located on the Yellowstone River, 35 miles north of Gardiner, and fish somewhere in the area practically every day.
