Potential visitors to England's largest lake are being told how a controversial speed limit will affect them.
The limit is being enforced using hi-tech speed cameras
Officials imposed the 10mph limit on Windermere in March, to the anger of some boaters and skiers.
The Lake District National Park Authority says the move will make the lake more peaceful and tranquil.
The organisation is now printing more than 50,000 leaflets in an effort to inform tourists how the speed limit will impact on their visit.
Campaigners against the speed limit already claim to have flouted it after they took part in a late-night skiing event on the lake within minutes of it coming into force on 29 March.
The new eight-page guide says that eventually the lake will become a less noisy place for everyone to enjoy.
It goes on: "A 10mph speed limit in Windermere means a safer, more enjoyable and bigger lake for people who want to sail, row, canoe, swim, fish and paddle.
"A speed limit for the lake was decided through a democratic process, a public inquiry. Everyone had a chance to put forward their views."
Members of the Windermere Action Force have pledge to carry on a campaign of civil disobedience against the speed limit.
They claim the speed limit will have an adverse effect on tourism.
