I have portaged into Murtle Lake several times.   on this paddle camp trip, I camped on Leo Island on the west arm.     The next morning I paddled to the north shore of the arm and landed at the trailhead for Central Mountain.   On a solo hike to this remote spot, I traversed the top of the mountain and looked down at the island from above, 3325 vertical feet below and 1.89 miles distant.    I continued on to loop down into the north arm, then hiked back, a long route, before paddling back to Leo Island.     Few people hike this route and the trail is overgrown and hard to follow.    A once-only hike.
