1 Walk out of the car park along the wide gated track to the earthworks that crown the summit of the hill. Head right, towards the trig point, and go around the grassy ramparts in an anti-clockwise direction. At the far side is a handy toposcope identifying what you can see - and what you can't. Apparently Boston Stump is 41 miles (66km) distant, but you'll need an exceptionally clear day to make it out.
2 Continue all the way around the embankment, until you're facing the gate you entered by, and here drop down the wide, stone-filled track to the right. This swings gently around and below the western edge of the hill, with the toposcope above. At the end go through two gates for a wide path around the field ahead.
3 Follow this across to the far side, but before you reach the lane go over a stile in the hedge on the right for a short path, clearly indicated, across the adjoining field. Look back at the hill behind you and see how prominent and imposing it appears. Imagine it topped with a forbidding wooden palisade, and wild, bearded men waving spears and yelling at you from behind. Still fancy attacking?
4 Go over a stile and turn right, into the lane, and walk this for ½ mile (800m), going straight on at the junction (signposted 'Little Dalby'). The lane swings right at Moscow Farm, which has an old-fashioned plough mounted outside a row of handsome brick sheds.
5 Approximately 420yds (384m) beyond the farm is a stile in the hedge to the right. Indicated 'public footpath', it leads along the right-hand edge of a rising field and then through undergrowth to the left of a small area of woodland called Burrough Hill Covert. However, the first 50yds (46m) beyond the stile can get quite overgrown in the height of summer, and if this is the case continue along the lane for a further 100yds (91m) and turn right on to an unsigned farm track. This public access route follows the left-hand edge of the field and makes its way gradually up the hill, steepening towards the top where the woods close in. The presence of a small spring, and the attentions of horse riders and cyclists, can make the upper section a bit boggy. The aforementioned footpath joins from the right just before a set of double gates. Go through these and continue up and along the grassy path straight ahead, following the bottom of a small valley.
6 The ancient defences are high above to your right. Do you think you can make it up the steep banks without being seen and enter the stronghold? (And will you have any puff left when you get there?)
7 When you reach the very top turn right and either follow the yellow-painted posts across the pasture for the main gate and the track back to the car park, or wander back over to the ramparts once more.
