You can hike to the hydroelectric station via Llactapata, a six-hour walk up and over a hill on the well-marked Inca Trail, affording views of Machu Picchu and access to a half-cleared ruin. The trail is well-marked and can be done without a guide, though they are helpful to indicate ruins, as well as the flora and fauna. Start early as it gets hot on the trail.
Hire a taxi to drop you off at the start in Lucmabamba. You can take a colectivo back from the Hydroelectrica, or continue on to Machu Picchu.
