My ds and his mates are wanting to go away on their own post GCSE's next summer but not sure what is sensible (or allowed if abroad) at this age. Initially they were talking about getting a train down to the coast and camping which I'm fine with but nowhere seems to allow groups of this age unaccompanied plus camping tends to be more remote than the local train station so no good for more than a few days. Lots of their friends are doing festivals which I'm not wild about (terrifying experience myself age 18 no doubt influencing my thoughts on this) but he wants to 'go on holiday'. One rich friend suggested a fantastic sounding organised adventure trek to Nepal but £3.5k for 2 weeks this isn't going to happen so wondering if there is similar out there but less ambitious/expensive. Anyone's 16 year old done anything exciting & adventurous you would recommend.
