There are multiple hikes on both sides of the Willoughby Gap with some pretty amazing summer views. We hike here in the summer and winter whenever we're back visiting Dakota's family. If you just want to check out the lake, it's worth the drive out to walk along the little beach or a stop to jump into the lake from the big rock.

Very local, very intimate, fun little barn brewery about 5 minutes outside of town.
An all-day cafe, market, & bottle shop in downtown St. Johnsbury, VT. Great coffee, natural wines, and delicious bites for breakfast, lunch, and dinner.
Rent some bikes and head out to explore the epic Kingdom Trails network! Stop by either East Burke Sports or Village Sports Shop to grab a rental, and grab a snack and a beer at the The Hub Trailside or Juniper's after you're done.
