The fires are part of the Countryside Alliance's "summer of discontent" aimed at alerting the government to growing anger in rural communities.
The organisers said they had registered each of the 2,800 bonfires across the countryside with the fire service.
But brigades across Hampshire, Oxfordshire, Somerset, Sussex and Devon were swamped with calls from concerned residents.
Protest march
An 8ft fake beacon which glowed with red lights, silk flames and smoke effects was also erected in the heart of Westminster in Parliament Square.
The action is set to culminate in a massive march in London on Sunday, which is expected to attract around 200,000 people.
Boarders from the prestigious Eton and Harrow public schools, are being allowed to take part in the march, according to The Times newspaper.
However, the Prince of Wales' office said Prince Harry - a pupil at Eton - would not be attending.
At the heart of the issue is the uncertainty surrounding the future of fox hunting.
The government is undergoing a six-month consultation process in an effort to draw up legislation.
Earlier in the year, the House of Commons voted for an outright ban on hunting, while the House of Lords voted for hunting to continue under licence.
Real Policies
Jill Grieve, spokeswoman for the Countryside Alliance, said: "We are bringing a message to parliament that the countryside is in trouble and needs help and we should be listened to.
"We will listen to whoever is in parliament, whoever is in power, as long as they have rational real policies which they consult the countryside on.
"We are the ones who are affected."
More than 2,000 coaches have already been organised to bring demonstrators to London from all over the UK.
However, concerns have been raised about a minority who are thought to be planning illegal disruption.
