Bridal Path over to Bottletop
When you ride out to the powerlines on the Hyannis trail, you will cross the bridge at the powerlines and start a small climb, at the top of that climb about ~50', take a sharp right into a trail. Not a super obvious entrance, but a few feet in and will open up, has a few board walks right at ground level to start, then follow that trail as it climbs up and intersects Neds, maybe 100m.
At that intersection with Neds, cut straight across and you are riding Greenland. At the end of Greenland to the left is the climb up to Bottletop.
