Public access points include city, county or state parks, or private camps along a river that charge a fee. In general, the farther one goes from swimming sites, the better the fishing becomes. A low-water crossing is a place where a public road crosses a river utilizing a low bridge that sits barely above water level. The best place to park at such crossings is at one of the four corners of the bridge. Popular spots are marked by the absence of grass or, unfortunately, by the presence of trash.
Private access is best, since it precludes other anglers from coming through.
Enticing one with a promise to catch and release only, and the offer of picking up any trash you encounter, may bolster your case. The landowner has every right to say no. An eight-weight is big enough to handle redfish, comparable to a saltwater popping rod. Keep in mind that all three components have to have the same rating to create a balanced outfit. Larry Sunderland of the Austin Angler fly shop recommends a six-weight system as a good place to start for most Hill Country fishing.
