Not a 'real' hiking trail that I know of up Tenney. But, there's a narrow, windy New-England style ski trail or two that could be condusive to hiking.
Also, if you haven't already been up it, being from Ashland, I'd recommend a trip up Plymouth Mtn./Pike's Peak. Better views up there than the top of Tenney I'd say...One of my favorite local hikes while attending PSU. Then there's Stinson or Carr close by which are nice as well....
