Well maintained and a few nice and well marked loops. Map at the trailhead for more. Most trails are on left side of the road but def some fun trails.
Take rt 3 to Duxbury, exit 11. Head towards Duxbury off the ramp and you'll hit a small rotary. Take first exit off it, Lincoln. Follow this for a bit then take Mayflower on your left. Park on left of road.
