Essential Gear for Trekking Bali's Volcanoes: A Complete Packing List

Trekking Bali's volcanoes requires more preparation than most people expect. While Mount Batur can be done in trainers by reasonably fit people, a summit attempt on Mount Agung demands proper gear, physical readiness, and safety awareness. Here's everything you need to pack — and what to leave behind.

Footwear

Footwear is your most important investment for volcano trekking. The upper slopes of both Batur and Agung consist of loose volcanic rock, scree, and ash — surfaces that demand grip and ankle support.

  • Best choice: Ankle-height hiking boots with a stiff, lugged rubber sole (Vibram-style). These provide traction on loose scree and protect ankles on uneven descents.
  • Acceptable for Batur: Trail running shoes with good grip. These are lighter and sufficient for the shorter, more moderate Batur trail.
  • Avoid: Sandals, flip-flops, canvas shoes, or flat-soled trainers. These offer no ankle support and minimal grip on volcanic surfaces.

Clothing Layers

Bali may be tropical, but summit temperatures can be surprisingly cold — especially before dawn. Plan for a layering system:

  • Base layer: Moisture-wicking synthetic or merino wool T-shirt. Avoid cotton, which stays wet and chills you.
  • Mid layer: A lightweight fleece or thermal jacket. Essential for Mount Agung; highly recommended for Batur.
  • Outer layer: A waterproof/windproof shell jacket. Even in dry season, summit winds and occasional cloud cover can drop the temperature significantly.
  • Bottoms: Lightweight trekking trousers or leggings. Shorts are fine for Batur in dry season but not ideal for Agung.
  • Hat and gloves: A beanie and lightweight gloves are worth carrying, especially for Agung where summit temperatures can approach 5–10°C.

Lighting

You will be hiking in complete darkness for much of a sunrise trek. A headlamp is non-negotiable — a phone torch is not a substitute as it drains battery and leaves your hands occupied. Bring fresh batteries or a recently charged rechargeable headlamp. A backup torch or extra batteries adds minimal weight and significant peace of mind.

Hydration and Nutrition

  • Water: Minimum 1.5 litres for Batur; 2.5–3 litres for Agung. Dehydration is a real risk during physical exertion, even in cool morning temperatures.
  • Snacks: Energy bars, nuts, dried fruit, or chocolate. Eating something every hour maintains your energy on longer climbs.
  • Electrolyte tablets: Useful for Agung and longer treks where you're sweating significantly.

Safety Essentials

  • Trekking poles: Particularly valuable on descent when loose scree puts pressure on knees. Collapsible aluminium poles are easy to pack.
  • Basic first aid kit: Blister plasters, pain relief, antiseptic wipes, and a bandage. Small and lightweight but genuinely useful.
  • Dust mask or buff: Fine volcanic ash and dust is prevalent on upper trails and can irritate airways. A simple buff or N95 mask helps.
  • Fully charged phone: For photos, maps, and emergencies. Download offline maps (Maps.me or Google Maps offline) before you go.
  • Cash (IDR): Guide fees and any trailhead charges are typically cash-only.

What to Leave Behind

Keep your pack light. You do not need:

  • A heavy DSLR camera (your phone will handle sunrise photos fine)
  • More than one change of clothes (guides usually provide a bag drop at the trailhead)
  • Excessive food — a snack or two is enough for Batur

Renting Gear in Bali

If you haven't packed hiking gear, don't panic. Rental shops in Kintamani (for Batur) and Amed/Candidasa (for Agung) offer boots, trekking poles, and jackets for reasonable daily rates. Quality varies, so inspect gear carefully before accepting it. Your guide or guesthouse can usually arrange rentals with trusted local suppliers.
