The main market town on the Lleyn Peninsula, it has a population of just under 4,000. The town was given its charter as a borough by Edward, the Black Prince, in 1355 and a market is still held each Wednesday.
Today tourism is the main focus but the town grew around the shipbuilding and fishing industries and a nearby granite quarry. Pwllheli is the terminus of the Cambrian Coast Line which runs from Machynlleth.
Glasfryn Parc Activity Centre is situated 4 miles north of Pwllheli and has many activities on offer including a go-karting circuit, a quad bike safari, wakeboarding, ten-pin bowling and archery. Open all year round, Glasfryn Parc has a farm shop, soft play area, cafe and restaurant.
Nant Gwrtheyrn Heritage Centre provides visitors with the opportunity to discover more about the Welsh language, culture and the local environment; it is on the coast north of Pwllheli between Trefor and Nefyn in a former quarrying village.
