A Sturdy Walk is a series of 12 caches forming a circular walk of about 4 miles placed to coincide with the 2008 Dreaming Spires Cache Bash at Sturdys Castle. This is a family friendly walk (although you may struggle with a buggy in some parts) with not too much in the way of hills and roads, and no Micro's 
.
In the cache you will find a letter and a number which you should take note of and use it to help you find the Bonus cache.
From No 5 you can either turn right after the first gate and follow the river which can get very muddy and even flood, or go through both gates and cross the field which we would recommend especially if you have children with you. At the mid-way point you will find a bench with a wonderful view which will make a nice spot for a rest or even a picnic.
