Llama hiking, also known as llama trekking or llama caravanning, is an activity where llamas accompany people on hiking and walking trips, including eco-tourism. Expeditions can last from as little as a few hours to several days. For longer trips the llamas often carry up to three days trekking supplies or cargo in purpose-built pack saddles so the people with them can carry as little as a day backpack. Treks are also offered, accompanied by the closely-related alpaca.

Llamas have padded feet similar to those of a dog, which lets them easily traverse steep and rocky paths while being more environmentally friendly to the ground than horse hooves. They also can use narrower paths reducing disturbances to vegetation. Llamas have both a thick undercoat and a woolly topcoat which protects them from the cold. A three-compartment stomach helps them cope with poor quality food sources. A llama can carry about 25% of its body weight with no problem. So an average animal of 300 pounds (136 kg) can carry around 75 pounds (34 kg) of equipment in its packs.

Llamas' excellent endurance combined with biddable and peaceful natures makes them suitable pack animals for hill walking, unlike more stubborn animals such as mules. People that might not usually participate in endurance walking go llamas hiking, including couples looking for some romantic time together, or walking parties that include disabled children.
