Has anyone ever fished Joshua Creek Ranch outside of Boerne?

Yes, stayed there once for an extended weekend about 15+ years ago, lots of big stocker trout that will readily/easily take a well presented wooly bugger. There was a little fly shop/souvenir shop in the compound. First time I've heard of trout in the hill country other than the Guad. You should see the water boil during feeding time. Nice folks running the place. Great for bird hunting as well from what I've heard. Boerne is a very nice. It was a gift from the in-laws knowing I like to fly fish.

Here is the web$ite: http://www.joshuacreek.com/ Wow! Glad I didn't pay for that, but I'm sure its more expensive now compated to 15+ years ago. You really don't need a guide unless you've never held a fly rod ever, I guess.

Casting for Recovery has held their Texas retreat there each year for the last five years, in mid April. Soon thereafter, the water gets too warm for the trout and they either get caught and kept or die off. They've deepened the creek in the last few years, so it's harder to wade but easier to fish from the banks. I think they now also stock bass there. Beautiful Hill Country setting, willing fish.

The Reel Recovery retreat will be at JCR this November. Wonderful place, good food, nice folks!

Never fished that property, but the Guad below Waring is quite near there and lovely. (free too, though just bass and sunfish)
