Upper Sandy Haven

Upper Sandy Haven is a sheltered, estuary-style sea mark on the Milford Haven waterway in Pembrokeshire, offering generally calm conditions compared with open-coast venues. It can fish well for mixed estuary species, especially when you time it with moving water and fish the deeper run-channels.

• Best thought of as a tide-run mark: it often comes alive when the tide is pushing through.
• A good option when the open coast is rough, but it can be quiet on slack water.
• Expect a mud/sand/weed mix with occasional deeper gutters and drop-offs that hold fish.

Upper Sandy Haven sits in the Sandy Haven area of the Milford Haven estuary system, where sheltered creeks and channels feed into the main waterway. Access is typically via local lanes and footpaths to the shoreline, with fishing done from the bank around the upper reaches.

• Predominantly shore fishing on estuary banks; some anglers also fish it by small craft/kayak where appropriate.
• Access can involve short walks on uneven, potentially slippery ground.
• Banks can be soft underfoot (mud/silt), so plan entry/exit with the tide in mind.

This is a classic Pembrokeshire estuary mark where species can vary with season, water clarity and bait choice. Expect a mixture of flatfish, bass and estuary predators, with occasional surprises when baitfish are present.

• Bass: often best around tide-run, features, and where small fry are present.
• Flounder: a reliable target over mixed mud/sand, especially with steady tide movement.
• Schooling/estuary species (where present): e.g., mullet in calmer, clearer pockets (often better targeted with specialised tactics).
• Occasional predators: depending on season and baitfish, other species can show in the channel edges.
• Crabs can be a nuisance at times, influencing bait choice and presentation.

Upper Sandy Haven generally rewards simple, tidy rigs fished close to the bottom in the deeper channel or along crease lines where current meets slack water. Keep rigs robust enough for mixed ground and potential weed, but not so heavy that they drag in softer silt.

• Best approach: find the main run-channel and fish the drop-off/edge rather than featureless flats.
• Rigs: 1–2 hook flapper/paternoster or a simple running ledger for bass/flatfish.
• Baits: lug/ragworm, peeler or other crab baits (when crabs aren’t too aggressive), and small fish baits for bass when conditions suit.
• Casting: long casts rarely needed—accurate placement into channels and along seams usually out-fishes distance.
• Presentation: keep baits fresh, check regularly if crabs/weed are active.
• Stealth: in clear, calm water, lighter leads and a quieter approach can help, especially for bass and mullet.

This mark is mainly about water movement rather than big surf conditions. It often fishes best with a decent push of tide, and it can be more productive when slightly coloured water gives predators confidence.

• Tide stage: generally best on the flood and early ebb when current is strongest and fish patrol edges.
• Slack water: can be slow; bites often switch on as the tide starts to move.
• Water clarity: a touch of colour can help for bass; very clear, bright conditions can make fish cautious.
• Wind: being sheltered, it’s fishable in many winds, but strong winds can still affect comfort and casting.
• After rain: estuary marks can change quickly with freshwater run-off; expect variable clarity and debris.

Although sheltered, Upper Sandy Haven is still tidal estuary fishing with soft ground and changing water levels. Treat it with the same respect you would any mud-bank venue.

• Mud/silt risk: some areas can be soft—test footing and avoid venturing onto unknown flats.
• Tide awareness: the water can fill behind you; plan an exit route and avoid getting cut off.
• Slip hazards: weeded stones, roots, and slick mud can be treacherous—wear suitable boots.
• Low light: bring a headtorch and fish with care; uneven banks are harder to read at dusk/night.
• Respect other users: this is a shared estuary environment (walkers, paddlers, wildlife watchers).

Facilities can be limited right on the mark itself, so it pays to arrive self-sufficient. Nearby settlements and the broader Milford Haven area typically provide supplies, but not necessarily at the water’s edge.

• Parking: usually informal/limited near access points—park considerately and avoid blocking gates or lanes.
• Toilets/shops: not guaranteed close to the shoreline; plan ahead.
• Mobile signal: can be variable in sheltered inlets—don’t rely on it for safety.
• Tackle/bait: bring what you need; local tackle shops in the wider area can advise on current bait availability.

Upper Sandy Haven rewards anglers who read the water like a small river—channels, seams, and depth changes matter more than distance. A few small adjustments in where you place a bait can make the difference between blanking and steady action.

• Fish the current seam: where faster water meets slack, especially on the edge of bends and channels.
• Look for gullies and darker water indicating depth; flat, uniform shallows are often less productive.
• If crabs are stripping baits, use tougher baits and shorten soak times.
• Travel light and stay mobile until you find signs—baitfish flicking, bass swirls, or consistent knocks.
• In very calm, clear conditions, downsize terminal tackle and consider longer hooklengths for cautious feeders.

I’m not aware of a universal, blanket ban on angling specifically at “Upper Sandy Haven” as a named mark, but regulations and access rules can apply depending on exact shoreline ownership, nearby protected areas, and local bylaws. Always treat signage on-site as the final authority.

• Check for local signs regarding access, private land, or seasonal restrictions.
• Parts of the wider Milford Haven waterway can have port/harbour-related rules affecting activities near channels, moorings, or operations—verify locally.
• If you intend to use a bait pump, take crabs/mussels, or collect bait, ensure it’s permitted in that specific area.
• Be mindful of wildlife and habitat protections that may apply in estuary environments; if unsure, consult official local sources before fishing.
• Follow best practice: take litter home, avoid disturbing birds, and keep to paths where possible.
