Tips for Visiting Mount Frissell #

  • If aiming for Connecticut's high point (on Mount Frissell's slope), park at the nearby trailheads in Massachusetts and follow the marked route - the highest point in CT is on private or shared boundary land, so respect signage.
  • Summer and fall offer the clearest approach; spring can be muddy and winter icy.
  • Bring a topographic map or GPS - boundary markers and highest-point plaques are easily missed on faint trails.
