St Albans City to Potters Bar (Hertfordshire)
15 minutes direct from Mill Hill Broadway.
The countryside views are fantastic, and the scenery is extremely varied; a marvellous view of the rest of the route all the way to St Albans. A very enjoyable and varied route with a mix of fields, woodland, lanes, tracks and urban residential estates, plus a riverside walk; mostly good path and road or pavement with some muddier track and one or two extra-muddy fields. No pavement-less B-roads and all road crossings safe except one. Marvellous mid-point view across to St Albans. Rich wildlife (skylark, woodpecker, red kites, butterflies) and varied features including an air museum, a fishery and a gravel-extraction conveyor belt. Pubs at South Mimms and Tyttenhanger, plus a picnic area and WC at the Willows Lakes fishery. Note St Albans High Street is on the far side of the station.
Time: 4h–8h30
Lunch: Pubs at South Mimms and Tyttenhanger split the route into thirds, plus picnic area and toilets at the Willows Lakes fishery.
Warnings: The crossing of the A414 is uncontrolled on a dual carriageway with fast traffic, though there is a central median so you only cross two lanes at a time; some narrow kissing gates and barriers along the route, and a fair bit of mud in winter.
Walk details: Slow Ways.

St Albans City to Radlett (Hertfordshire)
15 minutes direct from Mill Hill Broadway.
A direct yet pleasant, largely off-road route following the River Ver across meadows and managed wetlands, then field edges, woodland, fields and tracks to the outskirts of Radlett, finishing on a quiet private road. The Ver meadows are boggy and may flood in winter (gaiters or waterproof boots advised); some steps and narrow paths and a small bridge. Passes the site of a Roman villa and fishing lakes at Frogmore that can encroach over the path.
Time: 2h30–5h
Lunch: Refreshments at Park Street, with a hotel by the M25 useful for those on a long journey.
Warnings: The Ver Valley water meadows are boggy and likely to flood in winter — waterproof boots or gaiters needed. Some steps and narrow paths. Can be muddy.
Walk details: Slow Ways.

St Albans City to Hatfield (Hertfordshire)
15 minutes direct from Mill Hill Broadway.
A fantastic Slow Ways route; a totally pleasant, easy to navigate, accessible, direct, and beautiful route; the complete forest bathing experience. An easy, flat route almost entirely along a disused railway line, the Alban Way, on paved and wide paths separated from traffic and shaded by trees. Accessible and suitable for all types of wheels; some find the tree-tunnel monotonous as there are no views. Follows the Alban Way disused railway almost the entire route, with displays at one of the former stations and benches to rest. Good pubs, cafes and shops at the St Albans end.
Woodland: half under tree cover.
Time: 2h30–5h
Warnings: A quarter urban.
Walk details: Slow Ways.
