River Whitewater viewed from the Deptford Bridge near Greywell. The river rises at springs near Biddon Grange Farm and flows northeast until it joins the River Blackwater near Swallowfield. The headwaters flow over chalk giving the clear river it's name.

Accessed via the towpath on the Basingstoke Canal, which makes for a pleasant walk, if sometimes a little busy, Odiham Castle is interesting to walk around. The towpath can get a little muddy!

This stunning former flour mill sits in the rural village of Greywell. In a particularly picturesque setting, the mill sits at the springs of the River Whitewater. The Three Castles Path, a long-distance hiking trail, passes right by and, if you follow it north, you'll reach Odiham Castle.

One of King John's three castles, this spectacular ruin sits on the edge of the Basingstoke Canal around halfway between Windsor and Winchester castles. Odiham Castle was built at the very beginning of the 13th century and was possibly where the king rode out from to sign the Magna Carta at Runnymede. Extended during the later 13th century, over the next 200 years it was sometimes used as a prison. King David II of Scotland was incarcerated here for over a decade although was allowed to keep a household, so it was possibly quite a pleasant stay. Used as a hunting lodge in the 15th century and ruined by 1600, the castle has a significant history. Today, you can visit for free.

Once a swing bridge, the lifting bridge was installed in 1988. Spanning a tranquil spot on the Basingstoke Canal in North Warnborough, the bridge can be lifted to allow narrow boats through. It's the only lifting bridge on the canal and you can find it just south west of Odiham Castle. If you're lucky, you might even see it in action.
