Of the 1,918 independently-owned attractions in the UK which charge admission and which feature in the Good Britain Guide, 722 have put their prices up this year, according to the guide's latest edition.
More than half of the 414 places owned by national organisations, including the National Trust, have also raised their prices, usually by a margin of around 10%.
"These price increases are hardly the way to attract more visitors, at a time when the British holiday industry is seriously worried about its future," said the guide's editor, Alisdair Aird.
Mr Aird held up the houses of parliament as an exceptionally bad offender. The increase in the cost of a tour from £3.50 to £7.50 marked Westminster out as the country's "worst price-hike villain", and the rise was particularly unpalatable because parliament was a body which "ought to know better". Mr Aird went on to express his alarm that "this year - against a background of near-zero inflation - so many holiday places have steeply increased their prices."
The guide also went on to bemoan the inconvenient opening times of many attractions, the fact that so many places stay shut for as long as half a year and subsequently have to limit their numbers when they finally open their doors; and the lack of effort to link attractions with places to stay and public transport.
However, all was not entirely doom and gloom. "On the plus side," Mr Aird went on to say, "is the amazing number of establishments that not only stay open for the whole year, but are absolutely free. This year we have been particularly impressed by the friendliness and helpfulness of all the people we dealt with in Scotland."
Mr Aird also praised "the thousands of volunteers helping to staff so many of the country's attractions, from little local museums to great historic buildings".
