Summary
Crinnis Beach (Carlyon Bay), near St Austell, is a long, gently shelving sand-and-shingle beach on Cornwall’s south coast. It’s a clean-ground venue that fishes well for bass, rays, smoothhounds, and winter whiting, with rocky points at either end offering extra variety. The bay is sheltered from prevailing westerlies but comes alive on a modest easterly swell, making it a flexible mark across the seasons.
Location and Access
Crinnis is the central beach of Carlyon Bay, just east of Charlestown and west of Par. Access has varied over the years due to ongoing seafront works, but public access is typically allowed via signed paths and seasonal ramps over the rock armour sea defences.
- Drive via St Austell: from the A390, follow signs for Carlyon Bay/Par; local signage points to Carlyon Bay Beach/Crinnis.
- Parking: use the Carlyon Bay/Crinnis Beach car park above the beach (charges may apply, seasonal hours). The area’s general postcode is around PL25 (St Austell Bay); check on-site signs as arrangements can change.
- Walk-in: a short to moderate descent; expect steps/temporary ramps and sections of large boulders (rock armour) to cross before you reach the sand.
- Terrain: mostly clean sand with shingle; firmer underfoot near the waterline, looser above the high-water mark. Rocky ground and low reef exist towards the ends of the bay.
Seasons
This is a classic clean beach with seasonal variety and bonus fish near the rocky fringes. Expect bass and flatties in modest surf, summer hounds on crab, and winter shoals of whiting after dark.
- Spring (Mar–May): bass (schoolies and better fish after onshore blows), flounder/dab, garfish from late spring, occasional small-eyed/thornback ray.
- Summer (Jun–Aug): bass (dawn/dusk, surf lines), smoothhound (peeler crab), ray (small-eyed/thornback), mackerel and scad on calm evenings, gurnard, dabs; wrasse/pollack from rocky ends.
- Autumn (Sep–Nov): bass (prime months), ray, gurnard, late mackerel/scad, increasing whiting after dark.
- Winter (Dec–Feb): whiting, dogfish, pouting, dabs/flounder; odd codling in cold snaps; rays in mild spells.
- Occasional visitors: sole on still summer nights, turbot the rarest of bonuses, thick-lipped mullet in calm, clear water.
Methods
Standard beach tactics shine here, with clean-ground rigs and fresh baits. Keep an eye on the surf line and gutters, and tailor range to conditions rather than always blasting long.
- Bottom-fishing: 2–3 hook flappers (size 2–1) for whiting/flatfish; pulley-pennel or long flowing traces (3–5 ft) with 3/0–4/0 hooks for bass/rays.
- Baits: lugworm/ragworm for flatties/whiting; peeler crab for bass and smoothhound; sandeel, squid, or mackerel strip for rays; razorfish and cocktail baits after a blow.
- Lures: metals and slim minnows for mackerel/garfish; 4–6 inch soft plastics or shallow divers for bass at first/last light, especially near gutters or rocky fringes.
- Casting range: many fish patrol 20–60 yards in a surf; rays/hounds can want 80–120 yards on calmer, clearer days.
- Tackle: 12–15 lb mainline with 60 lb shockleader; 4–5 oz leads (grips in surf), lighter plain leads for scratching; long, supple snoods for rays.
- Timing: dusk into dark improves catches year-round; scratch by day for flatties/gurnard, switch to bigger baits as light fades.
Tides and Conditions
The beach fishes on most states, but the flood and dusk/dark transitions are the headline acts. Easterly airflow is the swell-maker here, while strong westerlies often leave it calm and clear.
- Best tide: flooding tide from mid-ebb up to two hours after high; first of the ebb can also fish if there’s residual surf.
- Sea state: a modest, tidy easterly surf with some colour is prime for bass; small, neat swell for rays/hounds; flat clear seas suit scratching tactics or night sessions.
- Wind: light to moderate E–SE raises fishable surf; strong onshore easterlies can dump and weed-out the beach; W–SW leaves it sheltered but clearer.
- Time of day: dawn/dusk best for bass and mackerel; full dark for whiting, scad, dogfish, and rays.
- Seasonality: late spring to early autumn for bass/hounds/rays; late autumn–winter for prolific whiting and comfort fishing in lee of westerlies.
Safety
This is a generally safe, open beach but the rock armour and shore-dump deserve respect. Access arrangements occasionally change with local works; always follow on-site signs and marked routes.
- Rock armour: large, uneven boulders can be slick with algae—use both hands, wear boots with good grip, and avoid in big swells or darkness if unsure.
- Shore dump: when an easterly swell builds a steep bank, waves can knock you off balance—keep clear of the lip and set light drag.
- Tide: the beach narrows on larger highs; avoid getting hemmed against the boulders and plan an exit point before darkness.
- Weed and snags: drifting weed can load lines on onshore blows; step back from the shore to keep tips high and lines clear.
- Visibility: take a headlamp, spare light, and high-vis or reflective gear at night; carry a charged phone.
- Personal safety: a modern auto-inflate lifejacket is strongly recommended when fishing near rocks or water’s edge; don’t fish alone in rough conditions.
- Accessibility: not well-suited to reduced mobility due to steps/ramps and boulder sections; consider flatter alternatives like Par Beach if mobility is a concern.
Facilities
Facilities are decent in the wider area, with beach amenities variable by season. Don’t rely on year-round services on the sand itself.
- Parking: pay-and-display car park above the beach (seasonal hours/charges; check signs).
- Toilets: seasonal/temporary facilities may appear in peak months; otherwise use Charlestown or Par public conveniences before/after.
- Food/drink: pop-up beach bars/cafés have appeared in recent summers; year-round options in Charlestown, Carlyon Bay, Par, and St Austell.
- Tackle/bait: available in St Austell and Par; phone ahead for fresh lug/peeler in season.
- Lifeguards: typically no RNLI lifeguard cover—treat it as a non-lifeguarded beach.
- Mobile signal: generally good 4G coverage around Carlyon Bay.
Tips
Crinnis rewards mobile anglers who read the sand and react to conditions. Small tweaks in range and bait often out-fish a static approach.
- Find the features: look for gutters, bars, and slightly deeper seams—fish the edges rather than the flattest sand.
- After a blow: as an easterly eases and water clears, bass often move tight to the lip—fish large worm/crab baits or a slow-rolled SP.
- Hound time: May–July evenings with peeler crab can be explosive; keep traces long and don’t strike too early.
- Ray game: sandeel/mackerel wing on a clipped-down rig; leave baits out longer and keep the rod in a rest to detect slack-liners.
- Weed strategy: step back from the waterline to keep line angles high; switch to streamlined leads and stronger snoods when weed is heavy.
- Crowds: in summer, fish dawn, dusk, or after dark to avoid swimmers and to improve catches.
- Backup marks: if it’s too calm and clear, hop to the rocky ends at first light for wrasse/pollack, or try nearby Par Beach for flatties.
Regulations
Normal recreational sea angling is permitted here, but you must follow national and local rules. Always check the latest notices before your session.
- Bass (ICES Area 7d–h, incl. Cornwall): at the time of writing, typical measures include a minimum size of 42 cm and a closed retention period in winter, with a limited daily bag during Mar–Nov. Regulations are reviewed annually—check MMO/DEFRA for the current year.
- Minimum sizes/bag limits: Cornwall IFCA publishes minimum conservation reference sizes for species such as bass, wrasse, rays, etc. Measure and release undersized fish promptly.
- Protected species: all shad, allis/twaite, and angel shark must be released if encountered.
- Methods: no set-lines or unattended rods; be considerate around swimmers/water users—summer daytime lure/bottom casting may be restricted by beach activity.
- Access: the foreshore has privately managed sections; public access is usually allowed, but site rules (no fires, no camping, event closures) may apply—obey on-site signage.
- Environmental care: take litter and line home; avoid disturbing dune/vegetation backing the beach and any nesting birds on rocky fringes.
