Bicycle back road route, appx 12 km. Not recommended for cars.
Start on Highway 27 (the main beach highway). Ride the back road south 7.0km to where it turns SSE, and continue.
Follow the road SSE for 2.6km to a road going almost due south; this will take you 2.7km into San Eduardo.
(If you’re doing a car/key swap, your biking buddies can drive to San Eduardo on the Telchac-Motul highway.)
