Peru is one of the easier South American countries to visit solo, and Machu Picchu — because it is so well-trafficked by tourism — is one of the most straightforward stops on the circuit. For solo travellers, the main variables are altitude (Cusco at 3,400 m hits harder than many expect), the fixed-time entry tickets, and the Consettur bus that climbs from Aguas Calientes to the gate.
The planning is simpler than it looks. Book the train from Ollantaytambo (or Cusco–Poroy in season), the Consettur ticket, and your entrance ticket for a specific morning. Peruways packages all three in one checkout, which saves chasing three separate operators.
Safety-wise, Machu Picchu and the Sacred Valley are among the safer parts of Peru. Stay in Aguas Calientes or Ollantaytambo the night before an early entry; keep your passport on you (ID is checked at the gate and on the train); and if you want to meet other travellers, book a shared group guide inside the citadel — Peruways offers these for about $35.
Solo travel at Machu Picchu is more about pacing than courage. Give yourself three nights in Cusco first, pick a quiet entry wave (6 a.m.) and let the altitude do its work on your schedule.
