Nice place but well spooky. Loads of young American guys drowned there when they were practising for the D-Day landings 60-odd years back, they say some nights you can still hear their screams.
I never caught much there, it was meant to be good for rays I think.
There are some great places within half hour or so's drive, esp the rocks and inlets around Torquay - Berry Head, Brixham Breakwater and the sewage outfall (can't remember its name...), near Babbacombe.
I used to fish at Teignmouth a lot. Go on the end of the split there and you could buy live sandeels of the geezers in the huts.
I used to fish a falling tide, 12 or 15lb line on one of my pike rods and a 3oz lead, lob it as far as you can into the river, hold the rod up standing in the water as the tide drops and feeel for bites.
Truly wicked stuff. The harbour used to be good there for odd bigger bass, gars etc.
Going the other way the Dart estuary on the prom at Dartmouth used to be good mixed fishing and there's some good places around Plymouth.
Couple of the local papers down there have good fishing columns, Exeter Angling Centre or th tackle shop in Paignton used to be a good source of info, might be worth giving them a ring.
