You don't need six days to see the best of it

Steel Rigg to Housesteads, via Sycamore Gap

The single most popular short walk on the whole trail: from the Steel Rigg car park near Once Brewed, the path climbs straight onto the Whin Sill crags, passing the Sycamore Gap site (Milecastle 39) and continuing along the ridge to Housesteads Fort, roughly 4–5 miles depending on your exact start point. Return via the 122 bus back to Once Brewed rather than retracing your steps, or walk back the way you came for a there-and-back day of around 8–9 miles. This single stretch covers the trail's highest point (Windshields Crags, 345 m), its most-photographed gap, and its most complete fort.

Chesters to Housesteads, via the Temple of Mithras

Starting at Chesters Roman Fort in Chollerford, this route follows the trail west past Carrawburgh (Roman name Brocolitia), where the Temple of Mithras — built by soldiers around AD 200 and the only one of several known Mithraic temples along the wall still visible today — sits just off the path, before continuing to Housesteads. It's a longer day, around 7–8 miles one-way, and combines a cavalry bathhouse, an unusual Roman religious site, and the best-preserved fort on the wall in one route. The 122 bus runs this whole corridor, making a one-way walk with a bus back straightforward.

Birdoswald and the longest visible wall, with Lanercost Priory

A shorter, flatter option from the western half of the trail: Birdoswald Fort sits beside the longest continuous stretch of standing wall anywhere on the route, and a short detour off-trail reaches Lanercost Priory, a medieval Augustinian priory built partly from reused Roman stone, where the dying King Edward I reportedly rested for five months in 1306–7 during his final campaign against Robert the Bruce. This makes a gentle 4–6 mile round trip better suited to a family day or a lower-mileage day than the crags routes above.
