About this Route
This GPX uses the short southern route from Red Lane to the summit of Great Sugar Loaf and returns the same way. It covers 2.8 km with about 198 m of ascent, usually taking 1 to 2 hours. The distance is modest, but the final cone is steep, rocky and busy at popular times.
From the established car park on Red Lane, follow the worn path north across open ground. The first section climbs gently through rough grass and low vegetation towards the foot of the summit cone. Several tracks merge here, then the path steepens sharply through loose stones and rocky gullies. Hands may be useful for balance, although no technical climbing is required on the usual line. The summit at 501 m has wide views over the Wicklow coast, the Glen of the Downs and towards Dublin in clear weather.
Return by the same southern path. Do not descend onto one of the longer routes around the mountain if you need to regain Red Lane. Loose stones make the short descent slippery, and erosion is a serious problem where walkers spread across the slope. Keep to the established path, take turns on narrow rocky sections and keep dogs under close control around livestock.
The Red Lane approach is short, but the last rocky climb gives Great Sugar Loaf the feel of a much bigger hill.

Route Waypoints
Start from the established car park on the L1031. Park within the marked area and keep the narrow road and entrances clear.
Follow the well-worn path north across open grass. Several informal tracks run beside it; use the most established line.
Climb gently towards the obvious summit cone. Look back to identify Red Lane and the car park for the return.
Stay on the direct southern approach where tracks meet below the steep slope.
The gradient increases and the surface becomes loose. Allow descending walkers space on the narrowest line.
Climb through stones and short rock steps. Hands can help with balance, particularly if the rock is wet.
Reach the 501 m top. The small summit can be crowded, so keep bags and dogs clear of the main path.
Descend the same southern path carefully, avoiding loose shortcuts that widen erosion.
Essential Tips
This is the easiest and most popular route. Start early and be patient when passing on the steep summit cone.
The descent is short but slippery. Keep space between walkers and avoid dislodging stones onto people below.
Multiple shortcuts are eroding the slope. Follow the established path even when another track looks quicker.
Livestock may graze the lower mountain. Use a lead and never allow a dog to chase sheep.
Frequently Asked Questions
How long does it take to climb Great Sugar Loaf from Red Lane?
Usually 1 to 2 hours for the round trip. The route is only 2.8 km, but the steep, rocky final section slows you down, especially if it's busy.
Do I need climbing experience for Great Sugar Loaf?
No, you don't need technical climbing skills. The summit cone is steep and rocky with some scrambling where hands help with balance, but it follows an established path.
Can I bring my dog up Great Sugar Loaf?
Yes, but keep them on a lead because livestock graze the lower mountain. The summit gets crowded too, so keep your dog clear of the main path at the top.
