Enter through South Gate causeway past stone figures, then find dirt trails leading up to Angkor Thom's ancient wall. This 12km circuit runs completely above traffic — Zero tuk-tuk exhaust, total tree canopy cover.

Start 6am sharp from any gate entry. You'll pass wildlife, hidden jungle temples, moat views that tourists never see. Bring water — Absolutely no vendors once you're on the wall trail.

Takes 3-4 hours walking, 90 minutes cycling. Wooden boardwalks in some sections, but watch footing on ancient stone. Still part of your Angkor pass, but feels like secret Cambodia few visitors discover.
