It’s moderately challenging — great for active people but not extreme. The biking is mostly downhill (easy on the legs), rafting is class III-IV (fun but splashy), zip-lining is thrilling yet safe, and the final trek to Machu Picchu is about 8-10 km uphill but shorter than classic trails. Basic fitness is enough; no prior experience required for most activities. If you can bike or hike a few hours, you’re good!

The dry season (May to October) is ideal — sunny days, less rain, and perfect conditions for biking, rafting, and clear views at Machu Picchu. Shoulder months like April, May, September, and October have fewer crowds and great weather. Avoid January–March if you hate rain, though the jungle is lush then!

Essentials: quick-dry clothes, swimwear (for rafting and hot springs), comfortable biking shorts or pants, lightweight rain jacket, sturdy sneakers or trekking shoes, sunscreen, hat, reusable water bottle, insect repellent, small daypack, and layers (Andes mornings are cold, jungle afternoons hot). Most tours provide bikes, helmets, life jackets, and zip-line gear — just bring your energy!

Yes, very safe with professional guides, quality equipment, and insurance usually included. Altitude starts high (biking from ~4,300m) but drops quickly into the jungle, so acute mountain sickness is rare compared to other treks. Drink coca tea, stay hydrated, and take it easy the first day. Most people feel great by day 2 in the warmer lower elevations.
