Haslingden High School Sixth Form student Danny Caine, 17, and his girlfriend Anna West, 16, who attends Alder Grange School, Rawtenstall, are currently fundraising to cover the £2,000 the trip will cost.
They will be helping The Indigo Project – Gambia, which was set up by Jeana Harvey, who used to live in Cloughfold and now lives in Scotland.
Danny said: “Both Annan and I have been making cakes and selling them at our schools and we are holding a coffee morning on Saturday November 26 at 38th Rossendale Scout headquarters at The Warren, Peel Street, Cloughfold, from 10am to noon.
“Entry will be £3 and that includes refreshments and we will also have craft stalls, home-made cakes, a raffle and tombola.”
Anna has previously visited The Gambia and worked with the project to build a school playground.
They visited Jeana and Dave in Scotland in the summer, which is when they decided they would like to both go to The Gambia.
Danny, from Cloughfold, said: “I am studying sociology A level. It makes you think about other people when you see things on TV and it makes you want to do something. Making a difference is always good.
“We are both members of Seat Naze Explorer Scouts and we are hoping to meet up with a Scout group over there.
“We will be planting trees and fruit and veg for the school in the village and we will be handing out malaria nets.”
A friend of theirs, Bruce Flood recently raised £1,700 by being Sober for October and the money was used to buy items which Danny and Anna, along with other friends, distributed to the homeless in Manchester.
The Indigo Project – Gambia was set up in 2009 after Jeana, Dave and their son Elliot visited the country and they sponsored two children.
Over the years they have sponsored more than 110 children and carried out a vast range of education and health projects in the country.
