There can be few better ways to enjoy and explore the Northeast of Scotland than on the back of a bicycle but try and make sure it's a mountain bike if you intend to try some of the forest or off road routes.
Cycling is also the healthy option.
Cycling is good for building up your stamina and improving the muscle strength in your legs. Bear in mind that accidents can happen so wearing a cycle helmet is probably a good idea as is wearing something light coloured or reflective. A rucksack will also come in handy for those other essentials such as cold or hot drinks, light snacks and water proofs in case there's a sudden change in the weather. Although dieting and exercise are probably your last concern when on holiday the following table may be of interest to you to judge your calorie usage during your cycle journeys.
