The event began yesterday with live music, art exhibitions and a parade, and will run until Saturday.
The parade, entitled ‘The Greatest Show on Earth’, which was jam-packed with vibrant floats making their way down the High Street, kicked off at 1pm.
It was dedicated to ‘Mr Alderney Week’ Ray Parkin, who died last year and was involved with the organisation of the event for decades.
‘It’s all going fantastically well,’ said organiser Wayne Chandler.
‘There’s a very good turnout this year, it’s the best I have seen in ages. There is probably a couple of thousand people here at least.
‘It’s brilliant to have this many people here.’
This is the first year Alderney week has been open to tourists since 2019, with the 2021 event cancelled due to Covid-19, and the 2020 'bubbled' event only open to Guernsey visitors.
Mr Chandler said they had been grateful to welcome visitors from the Channel Islands, the UK and France.
‘Everybody is having a great time,’ he said.
The week will continue with a schedule filled with live music, family-friendly events and beach parties.
Today will kick off with a womble clean-up at Les Buttes, the daft raft race at Braye Beach, and the sandcastle competition later in the day. The weather is expected to be dry but cloudy.
