In reply to keithlackie: If you want to become a tutor in Outdoor Education, then a degree will be very relevant.
Are you after work as an Mountain Instructor, or as an Outdoor Education Instructor? If its the latter, then again, a degree (and even a post grad degree) would be highly valuable. Pay structures do incorporate this, however, if you're keen to head down the hard skills road of MIA/MIC, then a degree is perhaps slightly less relevant, although in order to remain in Scotland, to work towards these qualifications, you will probably end up working in some outdoor educational establishments.
Scotland is an awesome place to work in, however the weather and midge can be somewhat challenging at times! Its not too hard to mix it up with extended trips both personal and work abroad though. Certainly beats my former life as a quantity surveyor!
