Just before the cache location, the trail crosses Drake's Brook. That crossing could be testy if there has been recent heavy rain. As it is, it would be helpful to have a staff to steady yourself for the necessary jumping from rock to rock. That is the reason for the T = 2.5. Otherwise it's a 2.
The cache is a green-painted vitamin bottle with a few small trinkets. Hopefully no squirrels will think it attractive and haul it away.
