Halfway Mountain is just to the west of Diamond Mountain and can be accessed from the Reeves Meadow visitor center. However, to avoid the crowds, it is best to start this loop from the Sebago Lake parking lot. From the Sebago Lake parking lot, walk to the lake and on the left is an unmarked trail. This trail follows the lake shoreline, weaving through the forest until reaching an open area and a dirt road over the levee that creates Lake Sebago.  At the end of the levee is a private property driveway so it is best to walk up to Seven Lakes Drive before you access the levee. Walk Seven Lakes Drive for a short distance until you reach the Lake Sebago Dam. Cross the road and you will see red markers indicating the Tuxedo-Mount Ivy trail. Step over the guard rail and scamper down the steep grade to the Stony Brook.

Hike a short distance along the brook until you reach the beginning of the Hillburn-Torne-Sebago Trail (H-T-S on maps with orange markers on trail).  The H-T-S Trail is flat until the trail crosses Diamond Creek then it is an immediate steep climb over rocky terrain for 0.5 miles.  The H-T-S trail tops out on the Diamond Mountain ridge and joins the Seven Hills Trail sharing the same path. After 0.3 miles, the H-T-S Trail breaks off to the right and descends off Diamond Mountain ridge. After 0.5 miles to ascend to the ridge of Halfway Mountain. There are not many view points but this section is nice in fall and winter with open forest views and rock outcroppings.

After a steep descent off Halfway Mountain, the trail reaches the Kakiat Trail (white markers). Turn right on the Kakiat Trail and follow to the convergence of Pine Meadow Brook and Stony Brook. The Kakiat Trail meets the Stony Brook Trail (yellow markers) at this point. Turn right onto the Stony Brook trail and follow for 1.3 miles until the Stony Brook trail ends at the H-T-S-Trail.  Follow back to the Tuxedo-Mount Ivy trail and to Seven Lakes Drive. Follow the road back to where you can gain access to the unmarked trail you followed at the beginning of this adventure.
