From the east, probably the best way to get to Grout Pond is via Kelley Stand Road, a twisty one lane dirt road that heads east out of East Arlington in Vermont. Pay careful attention to this map, it’s easy to get lost in East Arlington or East Kansas. I know I ended up at Covered Bridge in Chiselville the first time I got there.
Grout pond isn’t the biggest in the world. If you want lots of open water, check out the Somerset Reservoir. This area, however offers either backpack-in camping along the east shore, or 25 drive-in campsites, in a primitive campground nearby. There is no charge to use this National Recreation Area. Other roadside campsites along Kelly Strand Road, FR 71, and FR 70. Forest Road 70′s campsites are particularly nice, and it’s a 1/4 mile portage down to Branch Pond (bring wheels).
The lake is very shallow and marshy in one. Supposedly good fishing if you have a Vermont State Fishing License.
