Here are some things you can do and places you can visit.
Cruickshank Botanic Gardens: Located on the King's College campus in Old Aberdeen, the Cruickshank Botanic Gardens are well worth a visit and contain displays of interesting alpine and sub-tropical collections, as well as a delightful rock and water garden.
Craigievar Castle: This delightful castle with its small towers, crowstepped gables, round oriel windows, quaint conical roofs, ornamental stone cannons and decorative zigzag console is proof that fairytales do come true.
The Aberdeen International Youth Festival: This annual 10-day festival features daily performances by amateur groups from around the world. Although all artists are under 23, performances are always of the highest quality and includes everything from opera, orchestral, choral and chamber concerts, to dance and theatrical performances, as well as art exhibitions.
The Cairngorms: Britain's tallest and largest mountain range, the Cairngorms are home to the country's largest expanses of native forests and are widely regarded as one of Scotland's most stunning places of natural beauty.
Aberdeen Maritime Museum: Located in the interesting old 16th century Provost Ross's House, the Aberdeen Maritime Museum boasts an excellent collection of models, photos and paintings documenting the development of the Dee estuary's port, as well as the tough life of the whale-hunters, herring fishermen and North Sea traders.
