  • Walking on Sears Island

    There are many places to walk on Sears Island; the island is 2 miles north to south; maintained trails are marked *; mileages on trails are approximate.

    Shoreline Trail – about 5 mi. around; some places are impassable when the tide is in because of steep banks, so please consider the tide before you start;

    Jetty Road – about 1.5 mi., most of which is paved; for a lovely view down the bay walk up the rise on the left at the end of the road, to a space next to some birches;

    Tower Road – the gravel road that branches left off the paved road – about 2 mi. from the gate to the tower now used by cell phone companies; from the tower it’s about 300 yds. to a high bank at the shore, this path is overgrown;

    *Homestead Trail – about 0.67 mi., begins at the apple tree on the northeast end of the island and comes out to the Tower Road; just before a field look to the left for remains of the cellar of the old farmhouse;

    *Loop Trail – about 0.4 mi., begins and ends at the Tower Rd., branches arching overhead are charming in winter snow and peaceful any time of year;

    *Blue Trail – about 0.35 mi., begins beyond Loop Trail off Tower Rd. and leads to a beach with views to east and a nice spot for lunch;

    *Green Trail – accessed from the Jetty Rd. and leads about 0.6 mi. west, across a stream to the west shore; you can walk back to the gate along the shore at half tide or lower.
