How to get there
From the intersection of Route 9N and Route 74 in Ticonderoga follow Route 9N south toward Hague continue for around 18-miles to the trailhead for Deer Leap on the left, parking in on the right.
From the trailhead you will start following along an old woods road which gradually climbs parallel to the road for a bit but quickly swings away. The climb is moderate for the first 0.6 miles to the intersection with the Deer Leap Trail. Take more of a right at this point and you will start climbing into the Tongue Range. Brown Mountain is the first mountain in the Tongue Range but is a nice climb as a standalone peak. From the intersection the climb continues and is much steadier with small steeper sections along the ascent. There are nice views out over the lake to the east. The trail continues over the top to Fivemile Mountain. This could be a nice one way hike is a second car is available; Fivemile Mountain is best approached from the southern trailhead.
