Bad weather brought the mud to campers for the Wakestock festival. Enlarge Image

Music fans were spoilt for choice with Sesiwn Fawr in Dolgellau, and Aberystwyth's week-long Musicfest.

One of pop's big attractions, Girls Aloud, performed at Pembrokeshire's Oakwood theme park on Saturday night.

But Wakestock, one of the largest wakeboarding events in Europe on the Lleyn Peninsula, was partly cancelled.

The sold-out event which began on Friday, features wakeboarding - a version of snowboarding on water - along with a music festival.

But North Wales Police said conditions at the main festival site got so bad that the main walkway across the field was swept away.

Waist deep

Officers said the site had become impassable to vehicles, and ambulances were unable to get to the medical tent or to the campsite.

Large numbers of people had been wading waist-deep through the swollen river to get to the car parks and to Abersoch, they added.

Organisers announced that although the wakeboarding competition would still take place at Pwllheli Marina, the Saturday night music festival had been cancelled because of severe weather conditions.

They said the campsite would remain open until 1500 BST on Sunday, but urged people to travel home or make alternative arrangements if possible.

The announcement followed the cancellation of the Llangollen fringe festival because of the weather.

Organisers said all ticket money would be refunded.

In south Wales, the route of the Swansea Bay Rally was shortened.

Organisers said the Walters stage near Glynneath had been cancelled, and the main spectator area at the Walters Arena was being closed.

But elsewhere a variety of events continued despite the bad weather.

At the Sesiwn Fawr (Great Session) in Dolgellau, headliners on the main stage included Irish band the Dubliners, and folk singer Meic Stevens.

In Pembrokeshire, Girls Aloud headlined the Saturday night concert organised by two teenagers who began organising rock concerts in their spare time, and now run Mint Gigs full-time.

Speaking before the concert, Alex Darlington and Aaron Kirkhouse, both 19, said the show would be a "completely unique" family event, culminating in a firework display.

Classical music lovers travelled to the Musicfest in Aberystwyth, which is this year celebrating its twentieth birthday.

With lunchtime concerts, afternoon master classes and workshops, organisers said there was "a time, a place and a piece of music" to suit everyone.

Meanwhile, Margam Park's two-day balloon "fiesta" near Port Talbot, offered fairground rides for all the family, as balloons take to the skies by day and by night.

Organisers of The Royal Welsh Show in Llanelwydd which begins on Monday, said it would still be going ahead.
