The Watson Fall Trail is only 0.4 mile long but it's all up-hill. The grade is gentle but expect your thighs to let you know they are working just before you reach the wooden bridge crossing Watson Creek. It is a beautiful walk through an old-growth forest beside Watson Creek and moss-covered boulders. Although considered a challenging trail, it is constructed with lots of switchbacks and wide enough for hikers to walk side-by-side.
