Moderate fitness with ability to walk uphill at high altitude; expect sustained climbs and steps.
Cross Lake Titicaca by boat, climb the ancient Inca steps on Isla del Sol, drink from the famed Inca Fountain, and stand above the ruins of Pilcocaina with sweeping views of the lake. This full-day from La Paz blends archaeological intrigue with a demanding high‑altitude walk.
The day begins before dawn on the shore of Lake Titicaca, the water a flat, iron-gray mirror that seems to hold the sky in place. You step onto a low motorboat and the lake wakes with a huff—currents nudging the bow, gulls interrogating the wake—and the city of Copacabana recedes into a ribbon of red roofs and whitewashed church towers. An hour and a half later the boat eases into the pebble beach of Isla del Sol, where stone steps worn by the Inca rise immediately into the sun.

Spend at least a day in La Paz to adapt to 3,800–3,900 m; altitude affects pace and breathing on the Inca steps.
Bring 1.5–2 L of water and high-SPF sunscreen—the sun is intense at altitude and reflections off the lake increase exposure.
Wear sturdy hiking shoes with good grip for uneven stone steps and occasional scree on island paths.
Small vendors and tips are usually in bolivianos; have small notes for purchases at Copacabana markets.
Isla del Sol was an important sacred site in pre-Columbian Andean cosmology; Pilcocaina served ceremonial functions tied to the Inca sun cult.
Tourism here is high-impact on fragile soils and archaeological sites; stick to marked paths, avoid touching ruins, and use local guides to support community-based conservation.
Support and grip for ancient stone steps and uneven island trails.
Keeps you warm and blocks sharp winds coming off the lake, especially early and late.
winter specific
High-altitude sun is strong—bring broad‑brim hat and SPF 30+ sunscreen.
summer specific
Keep hydrated through the day; bottles stay cooler in sunlight and reduce plastic waste.
