Tips for Visiting Tatamailau #

  • For the summit push, start before first light - the trail is steep and early starts avoid heat and afternoon storms during the wet season.
  • Hire a local guide from the nearby town of Gleno or Hatolia; local guides know the best routes, campsites, and how to move safely on steep volcanic slopes.
  • Acclimatize for a day or two in the Ermera region - don't attempt a rapid ascent from sea level on the same day.
