Inca Trail is 11.4 mi (18.4 km) from central Machu Picchu, why not stop by during your stay. Why not take a stroll along the riverfront and watch the sunset while you're here? Machu Picchu has other activities you might want to enjoy such as Aguas Calientes Hot Springs.
If you're planning a bit of sightseeing during your trip, head to Ollantaytambo Archaeological Site— just one of the monuments in central Ollantaytambo.
