Situated two miles up the River Glaslyn Estuary, Porthmadog is a very popular visitor location at the bottom of Snowdonia. It is the terminus for both the Ffestiniog Railway and the Welsh Highland Railway.  The town owes existence to the slate quarried in the hinterland though the causeway was built much earlier to reclaim the land behind it for agriculture.

The causeway forced the drainage water down the north side of the estuary which scoured out both the harbour and the approach channel thus it became the “natural” place from which to export the slate. This industry thrived until the end of the First WW when the lucrative German market declined and with it the industry.

That left a township full of ancillary services for the export of slate (they had had a thriving ship building industry) and it reinvented itself as a tourist town serving the Black Country. The narrow gauge railway which had brought the slates down from the quarries closed and was rescued by enthusiasts of steam railways in the 1950s and is a national, if not international, treasure.

It, and its neighbours, are off the beaten track so to speak and, as part of a Cardigan Bay cruise, would make an ideal destination. 

Approach

The Red and White Fairway Buoy is in the position marked on the 2022 UKHO chart.............

.......  The UKHO chart soundings bear no relationship to reality and the approach channel is over what were drying sandbanks.

From the South West you will have to skirt round the Sarn Badrig before heading NE towards the Fairway buoy of the estuary or from the West it’s just a matter of heading towards the estuary located between Criccieth Castle (a couple of miles NW) and Harlech Castle (a couple of miles to the SE).

If you are coming up Cardigan bay from, say, Barmouth, the East Passage (inside Sarn Badrig) is eminently doable from about half tide onwards in fairly settled conditions, the lowest sounding is 1 metre and we’re told that the local boats use it all the time.

Once you have located the Fairway buoy you should look East for the Port and Starboard lateral buoys marking the entrance to the channel which is buoyed all the way up to the harbour.   Make your approach in the last 2 hours of the flood and, if you have more than 1.5 metres draft it is recommended that this be reduced to one and a half hours either side of HW.

We have included a chartlet of the approach with the approximate positions of the channel buoyage; these buoys are moved on a regular basis as required by the drifting sandbanks so this chartlet should not be used for navigation. (this proviso is for real, not just to cover our legal rear!!)  The course from the Fairway Buoy is basically East turning NNW in the vicinity of the No3 buoy and parallels the coast before turning NNE towards the White house on the UKHO chart where it then turns NE and skirts along the North shore of the estuary to the harbour.

Berthing, Mooring & Anchoring

Your choice here depends on what you like; the Yacht Club owns.....

..... and services the pontoons on the left as you enter the harbour proper and they have electricity and water with the club close by for showers etc. They are charging £20 a night for those berths in 2022.


If you are happy to tie up against the quay or moor on one of the harbour’s deep water moorings then that will cost you £8 a night. You will not have shore power or water and will have to walk round to the yacht club to use their toilets and showers (Coded entry which you will need to avail yourself of when they are open)

If you intend using a YC berth you will need to contact them on their phone, or by email, to arrange a berth before your arrival, otherwise just call the HM on 12 or 16 (office hours) to be allocated a spot.

The yacht club website is at http://www.madocyc.co.uk/

Facilities

On the YC pontoon you have all the facilities of a marina; shore power, water, showers and toilets. On one of the harbour moorings you will only have water which has to be collected in containers; you pays your money and takes your choice!  The harbour has its own diesel supply on the quay but petrol has to be collected in cans from the petrol station just over the road from the harbour. Calor gas and Camping Gaz is obtainable from a source close by (ask the HM).
This is a good place for restocking the food locker there being several supermarkets with outlets here.

Eating, Drinking & Entertainment

A visit to Porthmadog would not be complete without a visit to the Ffestiniog Railway. This was the first railway to be “preserved” and, over the years has had much publicity. At the moment they do not require bookings for their “Standard” coaches but you would be advised to book for their “First” class. Obviously at the weekend you’d probably have to queue for tickets though they have told us they may be introducing on line booking. They have a website

http://www.festrail.co.uk/

The harbour has a Maritime Museum just by the HM’s office which comes recommended. Other than that, the steam railway has vitalised the local tourist industry and there are plenty of pubs, restaurants and hotels to choose from.>

Entrance to channel
Written by Merlin Taylor | 1st Sep 2023
Buoyed entrance has changed direction this year and needs to be approached from the north parallel to Black Rock Sands, liable to constant change
UPDATE SUMMER 2021
Written by Don Thomson 3 | 17th Aug 2021
I reviewed these notes in August 2021. A new chart and list of buoy positions has been added. The buoys here seem to go off station quite regularly so you should contact the harbour to get the latest info. Otherwise no changes.
Channel Buoys July 2018
Written by Navig8R | 14th Jul 2018
The channel buoys have moved again since the April NTM. The HM advised us to pass close to No 8 but there appeared to be plenty of water. There are some additional un-numbered buoys on the final stretch just before you enter the harbour. The pontoon at Madoc Yacht Club dries out just before the visitors berths so leave a little slack in your lines. The Yacht Club is excellent and there is a very authentic Thai Restaurant next door.
UPDATE SPRING 2018

I've uploaded the Porthmadog channel details to the Navigation Gallery but there may be a typo on the Number 4 Fairway buoy. There is also doubt about the charted position of the R/W buoy and the harbour has issued a NOTAM saying use the No 2 PHM as the Entry point for the channel
Fairway 2017

Find the Fairway First!

We had a lovely time in Porthmadog summer '16. It took us two attempts to get in. The first with failing light and a boisterous sea. We failed to identify any buoys in the broken water and we didn't want to get too close as the bar was a lee shore. We came back in the morning when the sea had calmed and the channel was easily identifiable. It does lead almost onto the beach at one point but that is where the deep water is so don't fret too much. Of course next year it may have changed. We were made most welcome at the yacht club, thanks.
Make sure you do a good sea stow before leaving as the bar tossed us around a bit and we departed in mild conditions. Is it worth the effort? Most definitely. Would I go again? Yes!
Update Spring 2016
Written by dononshytalk | 13th Apr 2016
These notes were reviewed by Don in April 2016. There has been a massive change in the approach channel and we have included a chartlet of the new approach in our Nav Images gallery. It is not of the best quality and we hope eventually that Porthmadog may eventually post it somewhere on the net. Charges have gone up a bit, otherwise no other changes.
