Killingly and Danielson: a plain guide to the town
Updated September 22, 2026
Killingly covers several villages — Danielson, Dayville, Attawaugan, Ballouville, East Killingly, South Killingly — with the town's business centred on Main Street in Danielson. This guide gathers the parts residents and visitors look up most: where the town offices are and when they're open, the library, and the parks and trails the town keeps.

What's happening in town
Killingly's Parks and Recreation department publishes a seasonal activity guide, and the town's own site carries the meeting calendar. The proposed Amazon warehouse — Project Husky — is the subject the Brief has followed most closely; our page on it gathers the hearings, the claims on both sides and the sources.
What we're still confirming
Park seasons and library holiday closures shift year to year; the details above come from the town's and library's own pages. If something here is wrong, tell us and we'll fix it the same week.
