6.7 · Rocks · Cornwall
A prominent rocky headland on the east side of St Austell Bay near Trenarren. Steep rock platforms give access to relatively deep, kelpy water (6–15 m at high tide) over rough ground. Best on the flood and into dusk; summer and early autumn bring prolific lure fishing, while nights produce conger, pouting and rockling. Exposed to southerly swell but often fishable in northerlies. Access is via a National Trust car park and the coast path, with a 15–25 minute walk and a steep final descent to limited ledges. Wear appropriate footwear and a PFD, check the swell, and avoid fishing in heavy seas or alone.

Worth fishing if you can hit the best window.

Where the data comes from. Weather and sea-state readings come from the Met Office and Open-Meteo forecast models, refreshed several times a day. High and low water are taken from tide-station predictions for this stretch of coast.
How the score works. Each window is scored 0–100 from the signals that most reliably move fish inshore: tide movement (a running tide carries food, so the last of the flood and first of the ebb are usually the prime spells), wind speed and direction (onshore wind stirs food into the surf — up to the point it makes fishing hard), sea state (a little wave and swell movement helps, heavy swell hurts), and weather — rain, temperature and light. Behind the headline number we score bite opportunity and comfort separately, and run a separate safety check on wind and swell. The size of the tide counts too: spring tides move more water than neaps, so the tidal range for this stretch of coast is weighed alongside the tide's direction, your target species and this mark — and unusually big springs strengthen the safety check, because the water rises faster and covers more ground.
Your target species counts. Pick a species below and the score also weights what we know about it — its season, preferred sea temperature, tide stage and sea state, and whether it feeds by day or night.
The rating is guidance, not a guarantee — conditions change fast on the coast, so always judge the sea in front of you before you fish.

Strong spring tides — the sea rises faster and reaches further up the shore than usual, so allow extra margin on access routes and cut-off points.
The fishing rating combines opportunity and comfort. Always check local sea conditions; the safety check is guidance, not a guarantee.
Spring vs neap tides. Spring tides have a larger difference between high and low water, so more water moves on each tide — usually stronger flow that stirs up food and gets fish feeding. Neap tides have a smaller range and generally gentler movement. The range here is compared with what is normal for this stretch of coast, and the cycle swings between springs and neaps roughly every week, following the moon.
Big spring tides: the water rises faster and covers more ground than usual — double-check access routes and cut-off points before you fish.

Black Head sits on the south side of St Austell Bay, a rugged National Trust headland between Porthpean and Pentewan. Deep water close in, kelp-fringed gullies and mixed rough ground make it a classic Cornish rock mark for lure and float fishing. It rewards effort with wrasse, pollack and summer surface life, and offers shelter in many prevailing wind directions.
Access is via the South West Coast Path, with the easiest approaches from Porthpean or the tiny hamlet of Trenarren. Expect a scenic but committing walk and some exposed ground near the fishing spots. Plan your route in daylight first if you intend to fish dusk or after dark.
The headland fishes like a classic rough-ground Cornish mark with lively summer sport and scratchier winter options. Expect resident wrasse and pollack, with pelagic species sweeping past in settled weather.
Lure and float tactics shine here over the rough ground, with bottom fishing best kept simple and sacrificial. Travel light, fish mobile, and adapt to water clarity and tide.
Black Head has depth close in and will give bites over most states, but timing improves results. Water clarity and sea state are the key variables.
This is an exposed cliff and rock mark with committing access. Treat it with the same respect as any high-energy Atlantic shoreline, even on calm days.
There are no facilities on the headland itself, and the walk-in means you should pack self-sufficiently. Services exist in nearby coastal villages and St Austell.
Think stealth and precision rather than heavy static fishing. The fish hold to structure and edges where tide brushes the kelp.
Recreational sea angling is generally permitted at Black Head, but you must follow national and local rules. Always check for updates with the MMO and Cornwall IFCA before your trip.
Bass: In 2024 the English south-west rule allowed up to two bass per angler per day at a minimum size of 42 cm during the open retention period (typically Mar–Nov). Outside the retention period it is catch-and-release only. Check the current dates and limits before fishing.
Tope: It is illegal to retain tope caught by rod and line in England; release unharmed.
Minimum Conservation Reference Sizes (MCRS): Cornwall IFCA/MMO publish sizes for species such as bass, wrasse (where applicable), mackerel and others; measure fish and release undersized specimens.
Marine protected areas: The headland lies on National Trust coastline; there is no local angling ban, but additional bylaws may apply to commercial gear. Anglers should avoid disturbing nesting seabirds and seals.
Access: Stick to public rights of way and NT guidance; do not cut new paths or climb fences. Night fishing is not prohibited, but be considerate to residents and wildlife.
Bait collection: Some local beaches and rocks allow hand-gathering of bait for personal use; observe local bylaws and avoid hammering living rock. Never use crowbars in SSSI features.
Litter and fish welfare: Take all line and litter home, and consider using barbless or crushed-barb hooks where practical for easy release.
Always verify the latest rules on the MMO and Cornwall IFCA websites before you go, as regulations can change mid-season.
