Forget Skegness, Cleethorpes or the Yorkshire Dales, the students at the William Farr C of E Comprehensive School are experiencing Central America.
A team of 31 pupils, who are split into two groups, left Welton and flew into Nicaragua last Monday, before tackling two community projects.
One group will be tackling a project to re-plant an area of endangered rain forest near Leon while the other will be helping to build a new classroom for a school for deprived children in Granada.
One group will start their journey in Nicaragua and travel through the country to Honduras while the other group will trek in the opposite direction.
The students’ expeditions will include four days on the Caribbean coast taking a Professional Association of Diving Instructors course.
They will also trek through Los Maribios volcano range. They will camp below the active crater of Volcan Telica (1061m), where there will be a chance to see active lava, and will pass the Volcan Las Pilas famous for its colonies of white-faced capuchin monkeys.
Each student has had to raise more than £3,000 for the 23-day adventure – many of them organising and running dozens of charity events over a two-year period to raise the cash.
Staff who are accompanying them on the trek have also had to undergo rigorous first aid and expedition training and both groups will be accompanied by highly trained leaders familiar with Central America.
They will also be taking donations from a former pupil and regulars at the Bottle and Glass in Scothern to put towards community work in the country.
William Farr School, which now has Academy status, has been taking pupils on expeditions across Asia and central and south America since 1999.
Deputy head teacher Simon Pickett, who will be leading one of the groups, said the experience for the pupils was life-changing.
“This isn’t a holiday for the students. The community projects and the trek through the landscape are a real challenge but a truly inspirational journey,” he said.
“We have seen pupils utterly transformed by the experience. The sights, the people and the cultures they are exposed to open their eyes to a completely different world.
“It’s hugely rewarding to see that positive effect on the students not only on the expedition itself but for the months and years afterwards.”
Head teacher Andy Stones said: “We know academic studies are hugely important but inspiring a generation of students to go out into the world and make a difference is a goal we aspire to.
“This expedition is one of the many ways we strive to help pupils get the skills, qualifications and motivation to set their sights high and achieve their goals.”
