A new environment
Many schools have been good at facilitating outdoor activities and outdoor school in their own local area in the recent years. It is good training and getting used to outdoor life but does not replace going with the class to a new natural environment for a full school week.
For some pupils, this contact with a new natural environment (pupils from the coast and lowlands travel to fresh water and mountains, and vice versa) will often be the first and perhaps only experience of another natural environment. And for some, experiencing a new element of nature becomes a turning point in a young life. If the travel time becomes somewhat longer by completely changing the natural environment, the learning value of coming 2-4 hours from home and seeing completely different crops and landscapes, villages and farms is so much greater.
