The Hundredth is an adult alumni celebration for former campers, counselors, staff, and longtime Warren friends. All attendees must be at least 18 years old.

Whether your last summer was five years ago or fifty, we'd love to welcome you back.

Friday, January 15, 2027.

Registration will take place through YMCA Camp Warren's official registration system. We'll share the direct link, opening time, and additional instructions before registration day.

In the meantime, get the cabin group chat going.

The Hundredth is an 18+ alumni event, not Family Camp. Childcare and youth programming will not be available during alumni weekend.

Want the next generation to experience Warren? We strongly encourage you to register for a summer session or Family Camp. Registration for the 2027 camp season opens November 11, 2026.

Yes! The Hundredth is just one part of Warren's centennial celebration. Special anniversary moments are being planned throughout the 2027 summer camp sessions and Family Camps, so today's campers and families can be part of the festivities, too.

Registration rates are per person. Overnight options include accommodations for Friday and Saturday nights, along with meals and weekend programming. Day passes are also available for alumni staying off-camp or joining us for part of the weekend.

• Cabin space: $300

• RV spot: $250

• Tent spot: $200

• Full-weekend pass without lodging: $200

• Saturday day pass: $150

• Friday or Sunday day pass: $50

Additional information about what's included with each registration option will be available before registration opens.

Absolutely. We're planning approximately 230 cabin beds, 25 tent spots on the A-Field, and 5 RV spaces in the pasture.

Overnight accommodations are limited and available on a first-come, first-served basis. Want to bunk with your old cabinmates? Get your group organized ahead of time! Each person will need to register individually when registration opens on January 15 and include their cabinmate requests. While we'll do our best to keep groups together, specific cabin assignments cannot be guaranteed.

Nearby hotel options are also being explored for alumni who prefer to stay off camp.

That's the idea! We want to bring old cabinmates, friends, families, and generations of Warren alumni back together.

Cabin spaces will be reserved individually, not as private cabin rentals. Our team will do its very best to honor cabinmate requests and keep groups together while making room for as many alumni as possible. Specific cabin assignments can't be guaranteed. 

Our advice? Make the group chat now, get your buddy list together, and have everyone ready to register on January 15!

Yes! Full-weekend and individual day passes will be available for alumni who aren't staying overnight at camp.

Whether you're coming back for the whole weekend or joining us for Saturday's celebration, there's a way to be part of The Hundredth.

Expect the Warren traditions you remember: campfires, camp songs, favorite programs and activities, time with old friends, and plenty of opportunities to reconnect.

A special banquet-style celebration is planned for Saturday evening. The full weekend schedule is still taking shape, with more details to come.

Yes, you may want to start practicing your camp songs.

Help us find our people!

Reach out to former cabinmates, counselors, co-staff, and friends. Share The Hundredth with your Warren circles, follow along on social media, and sign up for alumni updates.

We're also working with generation captains to reconnect alumni across decades. If you're interested in helping spread the word, we'd love to hear from you. Email us at campwarrenalumni@gmail.com.

You can still be part of Warren's next chapter!

The Hundredth is about more than one weekend. We're rebuilding connections across the alumni community and creating more opportunities to stay involved, share stories, volunteer, and support the camp we love.
