Packing Recommendations

Essential Layers

• Base: Merino wool/synthetic shirts (short + long sleeve)
• Mid: Fleece or lightweight down jacket
• Shell: Waterproof breathable jacket (Gore-Tex or equivalent)
• Bottoms: Hiking pants + lightweight shorts

Footwear

• Sturdy hiking boots (broken in)
• Lightweight trail shoes for valley days
• Wool socks (multiple pairs)

Gear

• 30-40L backpack
• Headlamp (long twilight, but dark nights)

Activity-Specific Advice

• Valley cycling/walking: Light layers, sun protection

• Glacier travel: Full mountaineering kit, guide recommended

June offers long days (15.5-16 hours daylight), blooming alpine meadows, and fewer crowds than July/August—but mountain weather changes rapidly. Check daily forecasts (MeteoAM, ARPAV, MeteoSwiss) and hut conditions before ascending.
