SRK Greenway
I haven't done it yet, but yes, there is a trail up there. The Sunapee-Ragged-Kearsarge Greenway, which is a combination and connection of a lot of older trails in the area, passes over the moutain (purist peakbaggers will note that the true summit is slightly off of the main trail). One possible starting point is at the Proctor Academy Field House.
The latest edition of the Southern New Hampshire Trail guide describes the route in detail.
I haven't done it yet and I'd like to get up there and bag both peaks so let me know if and when you plan to go.
