A different kind of listing: this is a Christian, group-only winter retreat — not a solo-child day camp like everything else on this page. Groups (churches, student ministries or parent-led) register together; individuals can't sign up alone.
Details change often — check with the program.
Listed in the GOkidOZ guide to December and February vacation camps around Boston as a heads-up for families already connected to a church or student-ministry group. Camp Kerith's Winter Camp is a Christian retreat built around chapel, worship and group bonding — not a general-audience day camp, and not something an individual family can sign up for solo. If that's not what you're looking for, browse every other winter camp on this page or the full winter guide.
