This is a great 2 hour out and back (plus whatever time you spend at the pond). Lots of dogs on the trail. If you do not use the coordinates from AllTrails to find the trailhead BEWARE - Sterling Pond is NOT in Underhill State Park (even though that’s what this page says!) I used my car’s GPS system since I didn’t have phone reception and I ended up at the Mt. Mansfield trailhead after setting Underhill State Park as my destination (both the Mt Mansfield and the Sterling Pond trailheads are on roads called “Mountain Road” so you might think you’re headed in the right direction but you’re not!). It took 30 extra minutes to drive to the Sterling Pond trailhead. If you’re not using the AllTrails Coordinates to get there, make sure you’re taking the road that takes you past Smuggler’s Notch Ski Area.
