Tan Penmaen Head can offer the largest shore-caught fish along the North Wales coast from the rocky stretch at Old Colwyn. This is a great spot for conger eels, lively bass and used to have a reputation for tope. The downside is a lack of cover from the prevailing onshore wind, though a good north-westerly creates a chop on the sea and the fish seem to feed with more confidence. Easy access is available from the promenade at Colwyn Bay and in summer it is a lovely walk to the Head or you can walk through the old quarry below the former 70 Degrees Hotel.
The straightforward route is to drive along Colwyn Bay Promenade (with the sea on your left) to the end. Park and walk along the footpath above the rocky shoreline. Fish are likely to appear anywhere, though the Head rock is probably the most popular spot.
