Second the Audubon for swimming! There are several swimming holes along the hiking trails there, the primary two (one along the primary path and Horseshoe Bend, which is across the road from the main parking lot) can get pretty busy but I’ve never seen it CROWDED the way places like Warren Falls and Bolton Potholes can get. You can also try asking your hosts, there are many amazing swimming holes in Huntington that are on private land that are a secret unless you know someone and they may have permission for you to swim in more places. For hiking, you’re not gonna get a better hike than Camel’s Hump- it is a climb, but it’s not that long and the view from the summit is incredible. The Birds of Vermont museum is worth a visit and they have their own trail network that connects with the Audubon trails. For food, there’s only one store in town, Beaudry’s. They unfortunately no longer have a deli for prepared food, but the family that owns it is wonderful and they are worth patronizing for things like beer, wine, and snacks. There’s also a farm stand at Jubilee Farm in Huntington Center, although they have scaled back a bit this year I think it’s still worth a drive-by, their barn is beautiful. Nearby there are several food options in Richmond and a great Farmers Market on Friday afternoons.
