The climb is pretty steep for the first half-mile. Soon you'll see a junction with the Helen Markt Trail -- don't turn yet, this will be the return link on your loop.
Keep climbing and enjoying the cascading water and wildflowers (in springtime) along the way. At 1.4 miles you'll come to a junction with the High Marsh Trail. You could shave a mile off this hike by turning left here, but I prefer to hike about another half-mile to the Laurel Dell picnic area, where I rest up from the climb and get back on the trail.
