All children in Wales should have a week in an outdoor education centre paid for by the Welsh government, a Member of the Senedd has said.
North Wales Conservative MS Sam Rowlands wants it to be a legal requirement and said it would cost about £13m a year.
He said it would be a "real benefit for children" in both education and health.
But there is also a call for the money to be additional funding on top of what is already provided.
The plan will be discussed in the Senedd on Wednesday, and if it is backed by members, he would proceed with a year of research and consultation to draw up the Outdoor Education (Wales) Bill.
