Travelling by train and bus on Sunday?

Is it possible to get from Invergowrie to the top of Glen Doll using public transport on Sunday?

Never heard of them places, but you could get a taxi, that's a form of public transport!

I cannot find a way on a Sunday

My best shot is as follows:

Bus from Invergowrie to Seagate Bus Station in Dundee, then bus (services 20, 20A, 22, 22D or 130) from there to Kirriemuir. Then a taxi to Glendoll Lodge. (As I recall, there is a limited weekday service as far as Clova, services 220 or 801, but nothing on a Sunday)
