01 / MISSION PROFILE
All three Welsh national parks, without turning it into a race.
Wales is compact: the transits are short, so two-night bases and a four-night St Davids anchor leave real time on beaches and summits with a baby and Percy aboard. Route planned, not yet driven — this file will gain field notes after the wheels turn.

02 / JOURNEY LOG
Fourteen days. One unhurried Welsh arc.
North through Llangollen into Eryri, over the Menai to Anglesey, down the Cambrian coast to a four-night St Davids base, then the Gower and the empty Tywi valley for the run home.
Worcestershire → Llangollen
Short shakedown leg. Walk the old railway line into town and see the Pontcysyllte Aqueduct — a World Heritage canal in the sky — with Castell Dinas Brân above the site.
NIGHT / LLANDYN, LLANGOLLENLlangollen → Beddgelert Forest
Into Eryri via Betws-y-Coed and Capel Curig. Pitch among the trees at Beddgelert Forest; the village, river and Welsh Highland Railway are on the doorstep.
NIGHTS 2–3 / BEDDGELERT FORESTYr Wyddfa mountain day
The van never moves. Ride the Sherpa'r Wyddfa bus to Pen y Pass for the Miners' Track, or take the mountain railway option from Llanberis. Full briefing below.
BASE / BEDDGELERT FORESTBeddgelert → Anglesey
Caernarfon Castle (Cadw) on the way, then over the Menai Strait to the island. Base near Benllech and Red Wharf Bay for two nights.
NIGHTS 4–5 / CAE MAWR C&MCAnglesey day
RSPB South Stack cliffs and lighthouse, Beaumaris Castle (Cadw), and Newborough forest and beach with Llanddwyn Island at low tide.
BASE / CAE MAWR C&MCAnglesey → Barmouth
Back over the Menai and down the Cambrian coast: Porthmadog, Harlech Castle (Cadw) on its rock, then the Mawddach estuary into Barmouth for a seafront night.
NIGHT 6 / HENDRE MYNACH, BARMOUTHBarmouth → St Davids
The long transit of the trip: Machynlleth, Aberystwyth and the Ceredigion coast road to Britain's smallest city. Four nights, sea views from the pitch.
NIGHTS 7–10 / ST DAVIDS C&CCSt Davids peninsula
Cathedral morning, then Whitesands Bay and the coast path. Abereiddi's Blue Lagoon is walkable from the site; Porthgain's harbour makes the lunch stop.
BASE / ST DAVIDS C&CCIslands day
In puffin season — roughly April to July — book a Skomer landing from Martin's Haven, or an RSPB Ramsey Island crossing from St Justinians. Boats book out — reserve early.
BASE / ST DAVIDS C&CCWeather-flex day
Intentionally unscheduled — the Skye rule applies. Fair: Stackpole and Barafundle Bay (NT). Foul: Oriel y Parc, Solva harbour and a fireside pub. Protect it.
BASE / ST DAVIDS C&CCSt Davids → Gower
East past Carmarthen to the Gower peninsula. Pitch overlooking Three Cliffs Bay, then the evening run to Rhossili and the Worm's Head viewpoint (NT).
NIGHT 11 / THREE CLIFFS BAYGower → Tywi valley
North through Llandeilo — Dinefwr (NT) and Carreg Cennen castle sit either side — into the empty upper Tywi valley below Llyn Brianne.
NIGHTS 12–13 / RHANDIRMWYN C&CCRed kite country
RSPB Gwenffrwd-Dinas riverside boardwalk, the Llyn Brianne dam viewpoint, and the NT's Dolaucothi Gold Mines twenty minutes away at Pumsaint.
BASE / RHANDIRMWYN C&CCTywi valley → home
Llandovery, the Brecon road and a Hay-on-Wye bookshop stop, then the border country back to Worcestershire. Unpack, weigh the lessons, file the field notes.
HOME / WORCESTERSHIRE03 / OPERATIONS BRIEFING
The details that keep the adventure easy.
Treat the St Davids block, the single-night Gower pitch and the mountain day as fixed points. Everything scenic around them can flex with weather, naps and the pace of the crew.
PRIMARY ASCENTBUS, NOT VAN
BDGSHERPA S2PYP
Beddgelert → Pen y Pass
Pen y Pass is the trailhead for the Miners' and Pyg Tracks, but its small car park is pre-booking only through the season and overnight campervan stays are not permitted in the National Park Authority car parks. Leave the Nebuchadnezzar pitched and ride the Sherpa'r Wyddfa bus from Beddgelert instead — the S2 serves Pen y Pass directly, and Nant Peris park & ride covers a Llanberis start.

VEHICLE PROFILE
5.98M LENGTH
2.98M HEIGHT
2.11M WIDTH
Coastal car parks in Wales frequently use height barriers — check before committing, and use campsite directions rather than the sat-nav on final approaches.
CREW RHYTHM
One major objective per half-day.
The best days leave room for feeds, dog breaks, weather changes and unplanned beaches. St Davids day 10 is intentionally unscheduled — protect it.
ROUTE CAUTIONSkip the Abergwesyn mountain road (the Devil's Staircase) between Tregaron and Rhandirmwyn in this itinerary.
Its single-track hairpins are no place for a 6-metre automatic. The A40 approach through Llandovery still delivers the full Tywi valley.
04 / UK ACCESS STACK
The same wallet, pointed west.
The permanent seven-membership stack from Expedition 01 carries straight into Wales — with one important difference: state heritage here is Cadw, not English Heritage, and the reciprocal terms matter. Carry physical cards; admission, booking and parking rules vary by organisation and property.
The castle key
English Heritage members get half-price entry to Cadw sites in the first membership year and free entry after the first renewal. On this route that covers Caernarfon, Beaumaris and Harlech — three of Edward I's World Heritage ring.
Wales is home turf
NT operates directly in Wales — no reciprocal needed. Stackpole and Barafundle, Rhossili and Worm's Head, Dinefwr and Dolaucothi Gold Mines are all on this route, and NT car parks are free with the card. Note: NT membership does not cover Cadw sites.
Puffins and kites
South Stack on Anglesey, the Ramsey Island boat from St Justinians and the Gwenffrwd-Dinas kite country boardwalk — the RSPB layer earns its place three times on one circuit.
C&MC + C&CC spine
Three of the six bases on this route are club sites — St Davids and Rhandirmwyn (Camping and Caravanning Club) and Cae Mawr on Anglesey (Caravan and Motorhome Club) — with member rates and the certificated-site networks as backup.
England's passes stop at the border
Forestry England membership does not cover Wales — forest car parks here are run by Natural Resources Wales and mostly pay-per-visit. RHS partner gardens and free Woodland Trust woods still apply for garden stops and Percy's decompression walks.
Run the numbers
The complete seven-membership dashboard — coverage, reciprocals and official links — now lives on the Journeys page, and the optimiser prices the whole stack against your actual plans.
05 / THE NATURE MATRIX
The living checklist.
This file’s six species from the Nature Matrix — the archive’s 354-species UK wildlife calendar — with their peak months lit. Gold entries are the rare ones: never promised, never chased. Tap a card to log a sighting, and four of six earns this file a bronze patch, all six turns it gold.

06 / EXPEDITION TOOLKIT
The calculators, the cover and the app deck.
Run this file’s numbers through the free tools, confirm your own cover, then let the installed app deck cross-check pitches, navigation and live conditions. A layered toolkit — never permission to ignore campsite arrival instructions, signs or local access rules.
FREE TOOLS / RUN YOUR OWN NUMBERSNOTHING LEAVES YOUR DEVICE
Take this file to the calculators.
Every number on this page is a starting point. Push the route, the days and the crew through the free tools — they run entirely in your browser, save to your device only, and need no account.
BEFORE DEPARTURECHECK, DON’T ASSUME
Cover and the flex layer.
Insurance and breakdown: confirm your own policy covers the vehicle, the crew and the territory for the whole trip — and cache the certificate, policy number and breakdown numbers offline before signal thins.
The flex layer: Woodland Trust woods are free to visit and useful for short decompression walks around transit days — search near the next fuel or overnight stop rather than forcing another attraction into the day.

07 / DEPARTURE CHECK
Ready the landship.
A short final check now prevents the unglamorous problems from hijacking the first few days.
Canvas clear, locked, verified
Pull the elevating-roof canvas clear, lower, twist-lock and physically check it — every departure, no exceptions.
Weigh the real expedition
Load exactly as you intend to tour and visit a weighbridge. The automatic's 370 kg must absorb crew, Percy, water and every bag — check total and axle weights.
Systems set for transit
Gas bottle off at the internal cupboard shut-off, fresh tank part-filled for arrival, waste and cassette empty, water heater drained down if frost threatens.
Leisure battery green
Battery charged, solar clean and reporting, hook-up cable, adaptors and USB leads aboard. Run the off-grid calculator for the no-hook-up nights.
Restraints rigged
Child seat installation confirmed on the belted travel seats, and Percy's crash-tested harness or crate anchored on the activity deck — Highway Code rule 57.
Cards and cover to hand
Licences, insurance app signed in and cached, C&MC and C&CC membership cards, heritage cards, boat-trip confirmations and the Travel Passport checklist run.
OFFICIAL RESOURCE DESK
Recheck before departure.

FOUND THIS USEFUL?
Buy the crew a coffee, if you’d be so kind.
Everything in the free archive today - the expedition files, the Nature Matrix, the seven calculators and the Trip Engine - is free forever. In future, we may offer paid expansions for people who want more. They will add to the free archive, never take anything away from it.
But if a file saved you a wasted weekend, or the Matrix put a puffin in front of your children, you are very welcome to stand us a coffee. It goes on diesel, ferries and the next expedition — which comes back up here, free, for you.
Fuel for the Nebuchadnezzar£10 · ONE PAYMENT →Entirely optional. One payment, never a subscription — and you can set any number up to ten at the checkout if you are feeling especially kind. No perks, no supporter tier, and absolutely no hard feelings either way.
