DERBYSHIREThe imposing 17th century Bolsover Castle dominates the local area. Within its confines is the Little Castle, a Jacobean building with vaulted ceilings and ornate fireplaces.
While the ruins of Old Hardwick Hall are interesting, the 'New' Hall (built alongside only a few years later as the showpiece of the great Bess of Hardwick), is one of the most impressive and atmospheric houses of England, made famous for its ornate plasterwork and tapestries.
One of the most dramatic places in Derbyshire to visit is Peveril Castle in the Peak District. The remains of the tower are not particularly spectacular, but the views of the surrounding countryside certainly are.
The Peak District, which straddles Derbyshire and Staffordshire, has its own treasures to explore, although a lot of the area was industrialised in times past. Among the places to visit is Dove Dale which derives it's name from the River Dove that passes through the valley of wooded slopes and limestone outcrops. You can walk along parts of the riverbank on a footpath. Another quiet corner to perhaps look at is Miller's Dale - a section of the River Wye south of Tideswell village - so named because of the two 18th century mills which were built nearby.
The Peak District also has some pretty wild and bleak parts - Kinder Scout, Mam Tor, and Taddington Moor, for example. And places with odd sounding names like Rushup Edge and Mam Nick Pass. You can also pick up on parts of The Pennine Way for a walk, or take a trip down the Speedwell and Blue John Caverns.
Don't forget Chatsworth House, one of the great country houses with formal gardens to match, and also Lyme Park near Buxton.
