The Walk has already raised more than £890,000 for local charities, owner John McCutchan is hoping for record numbers this year.
The walk is open every day for four weeks from 11 April to 10 May, with the hope that the previous record visitor number will be beaten.
That record is from 2019, when 23,000 people visited.
John said "Being our 50th anniversary makes it a very special year indeed on the Arlington Bluebell Walk.
"We will be open daily for four weeks, and of course supporting local charities is at the heart of what we do.
"There will be 19 charities managing the walks and providing the refreshments, and they will each receive a substantial donation from the overall proceeds."
John's late wife Carolyn created the garden around the farmhouse which has been renovated. This year, it has become a Royal Horticultural Society Partner Garden. John wants to do something special for the 50th anniversary.
He continued, "We have created a bird feeding station and we will be using a large screen to beam it into the catering area.
"What could be better than having a cup of tea listening to the birds? It will be so lovely.
"We aim to make improvements every year, and this year we are making 18 mobility scooters available. Back in 2019, they were used 500 times so I am confident this will be popular.
"We also have an excellent new catering team on site, which will give us a real boost too.
"Over the years we have raised £890.291 for local charities. That was always so important to Carolyn and myself."
The walk is open daily from today (11 April) until 10 May and entry is £6 for adults, £3 for children up to 16 years old or £16 for a family ticket (two adults and up to four children).
