    Fishing tips

    • Simcoe ice fishing is world-class — perch on shallow flats, lakers on deep rock piles.
    • Grand River smallmouth respond to tube jigs in current seams.
    • Walk well upstream from the parking lot for less-pressured pools. Use small roe bags in clear water conditions.
    • Access: Free parking at Glen Rouge Campground entrance. Trail access to multiple river pools.
