Essentials: sturdy waterproof hiking boots (ankle support is key), 3-layer clothing (moisture-wicking base, fleece mid, waterproof outer), a daypack (20-30L), sunscreen (SPF 50+), and a reusable water bottle. We rent trekking poles ($5/day), waterproof jackets ($8/day), and even portable oxygen canisters ($10) if you’d rather not buy. Pro tip: Skip heavy books—our guide carries a local flora/fauna guide to share!
