In reply to Olaf Prot:
Some great suggestions on here. In a few days you could do the crossing twice, or wander around a bit?
My route for a direct straight line is...Okey, Hangingstone Hill (via Army track), Quintins Man, then due S past both mock and real Statts House. Cross East D in Sandy Hole, then Lower White, and contour across to the gate next to Cherrybrook Hotel.
Then FP across Mudilake, Prince Hall track to Dartmoor Training Centre. Off paths across to the Swincombe and cross at the Island. Childes Tomb, Fox Tor, direct to Redlake (no easy way, but good for the soul...). Then tramway down to Ivybridge. Lovely.
Over a few days you could wander our west, stop a night at Fox and Hounds (bunkhouse and campsite), then to Princetown for another stop over, via Lane End, Standon Steps, Bagga Tor, Whitebarrow, Gt Mis, and North Hessary. Last day follow Abbots Way from Princetown as far as Crossways and then down the Redlake Track to Ivybridge for an easy finish!
