Millions of pounds could be spent on "breathing new life" into two outdoor education centres in North Yorkshire.
The council wants to modernise Bewerley Park in Nidderdale and East Barnby in the North York Moors National Park.
Thousands of children visit the centres every year and the council said the investment would enhance their appeal for generations to come.
If the first phase of the project is approved, the work would be completed by the end of 2025.
The work, costing £4.2m, would provide a new accommodation block at Bewerley Park with 84 beds and make improvements to East Barnby accommodation blocks and the dining room.
A separate decision on phase two is expected in 2027-2028.
The centres offer residential and day courses for primary and secondary schools, through to higher education, youth and adult groups. They are also used as venues for day trips and staff development.
Councillor Annabel Wilkinson, executive member for education, learning and skills, said: "This is an exciting project.
"For decades both centres have proven very popular, being visited by generations of families.
"It's vital that our centres continue to deliver wonderful experiences in a more modern environment."
