Is the altitude dangerous for toddlers?

Consult your pediatrician first. Generally, children over 2 handle it fine if you descend to the Sacred Valley immediately rather than staying in Cusco.

Can I use a stroller in Cusco?

Absolutely not. The streets are steep, narrow, and made of uneven cobblestones. Use a hiking carrier for babies and toddlers.

Planning a Stress-Free Family Trip to Peru with Kids

Focus on a 'High-Low' altitude strategy to help kids acclimate, and book private transport between cities to avoid the chaos of public bus terminals. Stick to a 'one activity per day' rule to keep children from getting overtired during high-altitude travel.

Build your altitude buffer. Fly into Cusco (11,152 ft) but immediately take a private car down to the Sacred Valley (9,000 ft). Spend your first 48 hours there to let the kids adjust to the elevation before heading back up to Cusco or Machu Picchu.
Book trains and tickets early. Book the PeruRail or Inca Rail tickets and Machu Picchu entry permits at least 3 months in advance. The limited-entry circuits mean you must choose your route—pick Circuit 2 for the iconic photo, but know it involves stairs that may be difficult for toddlers.
Arrange private transfers. Do not rely on local buses for family travel. Hire a private driver for 'point-to-point' travel (e.g., Cusco to Ollantaytambo). It costs about $50–$80 but allows you to stop for bathroom breaks and altitude sickness checks without keeping a full bus waiting.
Manage the itinerary pace. Limit activity to one major site per morning. Spend afternoons in town squares or markets where kids can run around and engage with local street performers or artisans.
