Overview

A more sheltered alternative to the high, exposed Robert Ridge, the Speargrass – Angelus Route climbs from the Mt Robert car park through cool beech forest beside Speargrass Creek before popping into the Angelus Basin and its showpiece lake. It’s varied, pretty, and serious enough to demand respect.

  • Length: about 7.5 miles one way (roughly 12 km) from Mt Robert car park to Angelus Hut via Speargrass Track and the Speargrass Creek Route.
  • Typical time: 5–6 hours one way in summer conditions; allow much longer if snow or ice are present.

Route Experience

The lower valley is classic beech forest tramping on a formed track with roots, mud, and many unbridged stream crossings. After Speargrass Hut (a common stop/overnight), the route continues up-valley, then climbs to a ridge and drops into the Angelus Basin. Expect rougher, poled “route” travel above the bushline with sections of scree and uneven footing. The final approach sits in a dramatic alpine amphitheatre beside Rotomaninitua / Lake Angelus.

Difficulty and Hazards

This is a tramping track that turns into true alpine route terrain. Multiple creek crossings can be swift or impassable after rain. Above the bushline, rapid weather shifts, strong winds, cloud/whiteout, and lingering snow or ice (especially May–October) are real risks. All approaches to Angelus carry avalanche exposure in winter. Mobile reception is patchy; carry a PLB. Treat or boil drinking water.

Best Time to Hike

November–April is the sweet spot for most hikers, with longer days and (usually) safer creek levels. Even then, cold snaps and high winds happen. May–October is only for experienced alpine trampers with winter kit and avalanche skills; progress is slower, daylight is short, and icy slopes are common.

Logistics and Tips

  • Start at the Mt Robert car park near St Arnaud (access via Mt Robert Road). Many parties break the trip at Speargrass Hut (about 3 hours from the car park in normal conditions) before continuing to Angelus.
  • Angelus Hut and the adjacent campsite require advance bookings year‑round. Speargrass Hut also requires bookings year‑round. In winter, Angelus Hut plumbing is disconnected; firewood is not guaranteed, and you may need to dig to reach the hut after storms.
  • Choose your weather window. This route is generally more sheltered than Robert Ridge until the final exposed ridge—ideal when ridge winds are howling.
  • Expect wet feet. Pack spare socks and use poles for creek crossings and scree sidles.
  • Insects: sandflies are common, and wasps are notably active January–April.

Comparable Option

If the forecast is calm and you want continuous ridge‑top vistas, consider combining this with Robert Ridge one way. On windy or claggy days, Speargrass is the smarter, safer-feeling approach.

Pros

  • More sheltered than Robert Ridge until the final ridge to the basin
  • Varied travel: lush beech valley, lively creek, then a dramatic alpine lake

Cons

  • Multiple unbridged creek crossings can be impassable after rain
  • Upper route can be icy or snowbound well into the shoulder seasons

Parking

Park at the Mt Robert car park, reached via Mt Robert Road from St Arnaud.

Caution

Unbridged creek crossings, rough poled route above the bushline, rapid weather changes, winter avalanche hazard, limited cell coverage; treat or boil water. Hut and campsite require bookings year‑round.
