A Butlins holiday camp was opened on the island on the headland at Nell's Point in 1966.

It was sold in 1986 having had its title changed latterly to Majestic.

The Wales Tourist Board provided assistance to the Barry Island resort in 1988.

The holiday camp closed in 1996.
In 2005 planning permission was given to convert the camp site into a housing estate.

The funfair on the ’Island is still in use as of 2019 having been closed for a couple of years but more recently re-opened with many new attractions.

In 1993 the Barry Joint Venture was launched by the Vale of Glamorgan Borough Council, Welsh Development Agency and the now defunct South Glamorgan County Council, later renamed the Barry Action Venture Partnership.
The main objective was to redevelop the waterfront around the number one dock, which was now derelict.

During the period when the West Pond area was being used for industrial purposes its soil became contaminated with mercury, asbestos and cadmium.

As part of the clean-up it was proposed to line the two disused graving docks with an impervious synthetic membrane and fill them with the contaminated soil.

In 1995 a court ruled in favour of this plan.

Planning permission was given for a series of major commercial and residential housing developments at Waterfront Barry.
In 2001, Morrisons opened a new branch at the site, and a 55,000 square feet (5,100 m²) non-food retail park adjacent to the site, was completed by 2004 and by 2015, the retail park hosted Pets at Home, Halfords, Argos, Pet Hut, Poundstretcher and a KFC outlet.
The fifth stage of the residential developments, a group of new apartments on David's Wharf, was announced in 2002.
By 2011 there were 686 new homes, a health centre, pharmacy, supermarket and 5,600 square feet (520 m²) of shopping space.

In 2007 a £350 million project was announced to develop 2,000 new homes and commercial properties in the waterfront area.
The proposed development included the West Pond reclaimed land to the west of the number one dock, the South Quay, East Quay and Arno Quay.
A £230 million version of the plan was approved in 2011, which included a new road linking the town centre to Barry Island, a school, hotel, restaurants, supermarket and public spaces.
The first of two new medical centres had been built by 2008, south of the Barry-Cardiff railway line and opposite Thompson Street and to complement this, by December 2009 a new pedestrian footbridge had been opened, spanning the railway line and linking Thompson Street with the medical centre and Morrisons, other retail outlets and new Waterfront housing.
In 2010, work had started on the construction of a new medical centre and pharmacy to become known as Westquay Medical Centre and a new pedestrian ramped access was being cast.
The new surgery was opened at the end of October 2010.
Like the, by then, Entrepreneurial Centre, already established alongside, the building stood on the site of the former Barry Railway Company's loco works and carriage sheds and on a level above the hydraulic engine house.
By February 2012, work had started on clearing the site opposite the old hydraulic engine house in preparation for building a new hotel and inn and by June 2014, was open to the public as the Premier Inn and Brewers Fayre pub and carvery.
 Further drastic change came by April 2015 when a new ASDA superstore with card-only fuelling facility was opened and this occupied most of land previously bearing the Powell Duffryn oil tank farm and former multiple railway sidings used latterly for storage of withdrawn steam locomotives held by Dai Woodham.
The extant structure of the ‘listed’ hydraulic engine house opposite the Premier Inn, partly renovated prior to 2012, was involved in further internal renovation and facial improvements and car parking facilities were being prepared in August 2015.
