Tips from the Community
Porthmadog came about after William Madocks (a guess this is where the name of the town derives from) built a sea wall, the Cob to reclaim land from the sea for farming use. The diversion of the river caused it to scour out a new natural harbour deep enough for small ships and the first public wharves appeared in 1825. Quarry companies followed, with wharves along the shore mainly for the transport of slate and due to this the town grew in population and importance.

The flat topped summit can be difficult in mist, hard to find the very top, and also to navigate off to find the route to Moelwyn Fach - you have to double back, and then descend to the right.

Surprisingly this is a two lane road and the amount of A roads around it means it was dead quiet even at peak school run time. But yeah it's a bit of a beast. Caught me out even after I'd ditched the luggage at camp. Would be a serious hill anywhere in England.

Great walk through a variety of tree species and easy to follow path. Would recommend going anti clockwise/reverse of suggested route as scenery coming back through gorge is stunning (with the bridge as a nice suprise at the end) and easier downhill as plenty of small steps. If taking a dog then be aware there is/are sheep grazing along the route but no stiles or fences to climb if you have a large dog but there are very steep banks/drops along the gorge so recommend keeping on a lead if they are a bit hectic! Would not recommend unless you have a basic level of fitness as some parts of the path are extremely steep.

According to tradition, the church was built on a site founded in the late 6th century by Saint Brothen, said to be one of the seven sons of the legendary Helig ap Glanawg. Most of the current church dates from the 13th century. In the 15th century the roof was renovated and the south portico and bell tower were probably added in the 17th century. The church was restored in 1844 and another restoration took place later in the same century when new windows were installed in the nave and the floor was tiled. In 2002 it was transferred to the charity Friends of Friendless Churches, who have a 999-year lease from 1 January 2005. (Wikipedia)

Porthmadog is simply a busy hub, a gateway to the Llyn Peninsula and Snowdonia National Park. It is a lovely harbour town with a gorgeous mountain backdrop. It also has a good range of shops and attractions including nearby Portmeirion, a narrow-gauge railway, a normal railway and guess what...an excellent hands-on railway museum!
