“We had our son’s 6th birthday party at Thorne and it was amazing. The children had so much fun learning about bugs and reptiles while playing games, catching bugs, holding a snake and making crafts. Our son said his party was “awesome” and other children told us it was the best party ever.”

– Bob and Laurie Cook, Parents

What will children do during a Thorne birthday party?

Birthday Parties include two hours of hands-on activities and nature exploration led by one of Thorne’s experienced environmental educators, with an additional 30 minutes to enjoy cake and refreshments at our beautiful site. The general flow of the program is to begin with a lesson indoors about the many living things that call Sombrero Marsh home.  Typically we dress the birthday child up like an insect, something each participant is sure to find while exploring outside, and educate everyone about insect body parts. Next, we set kids loose on our trails armed with nets, trays and magnifying glasses, field guides, and binoculars and then provide hands-on and fun learning experiences tailored to whatever they see, hear, and catch. If the children are completely engaged in exploring, we will spend the bulk of the time outside and return indoors in time for cake and refreshments.  If you have special activity requests, you can let us know and we’ll see if we can accommodate your birthday wishes.  Here’s the typical schedule for a Birthday Party. 

      • 9:45-10:00- Birthday family arrives and sets up
      • 10:00-10:15- Craft (e.g. Make-Your-Own-Creature) as guests arrive

Where will the birthday party be held?

Thorne’s birthday parties are held at the Sombrero Marsh Environmental Education Center in Boulder (1466 63rd St. Boulder, CO 80303). Thorne has indoor and outdoor play/learning spaces including interactive exhibits, a trail system with boardwalks, and 45 acres of open space including both prairie and wetlands.

Thorne schedules birthday parties on most Saturdays between the beginning of April through the end of October. We have two timeslots each Saturday – one from 10am-12:30pm and another from 1:30pm-4:00pm. We ask that you schedule your birthday party at least 20 days before your desired date. If you wish to schedule a birthday party at a different time of year, day, or time please contact us and we will try our best to accommodate your needs. CLICK HERE to see available times for Thorne Birthday Parties.

What is the cost of a Thorne birthday party?

The cost of a Thorne birthday party is $250 for 1 to 12 children and $400 for 12 to 24 children. When there are more than 12 children, Thorne will provide a second educator. Scheduling large parties is dependent on staff availability and cannot be guaranteed.

What ages does Thorne accommodate for birthday parties?

Thorne can arrange fun and educational birthday parties for youth ages 3-10.

How long are Thorne’s birthday parties?

Thorne’s birthday parties are 2 ½ hours in length which includes two hours of hands-on activities and nature exploration led by one of Thorne’s experienced environmental educators, with an additional 30 minutes to enjoy cake and refreshments at our beautiful site. Please let us know if you need more than 30 minutes because you are serving a full meal, and we can shorten the program time.

When can I get access to Sombrero Marsh to prepare for the party?

The Center will be open 15 minutes before and after the party for you to set up and clean up. It is important that you stay within this allotted time, as we may have another party scheduled the same day.

What equipment is available for use for a birthday party? What do I need to bring?

Thorne provides tables and chairs for your use – we have 5 tables that are 6’ (72”) and one that is 8’ (96”) as well as 30 chairs. Thorne also has a refrigerator, freezer, and power outlets. You can also leave your garbage, recycling, and compost with us after the party. We do ask that you bring your own cake, refreshments, table cloths, decorations, dinnerware, and party supplies if desired. CLICK HERE  for more information about the Sombrero Marsh Environmental Education Center and to see indoor and outdoor photos of the Sombrero Marsh site.  

Do I need to stay during the party or can I drop off my child/ren? Can families bring younger siblings?

We ask that the hosting parents stay at the Center during the birthday party, and welcome all families involved to participate. Younger siblings are also welcome, but we ask that parents supervise any children who are not part of the program.

What paperwork do parents need to do?

We ask that all birthday party attendees sign a Release and Indemnity Agreement.  If parents will not be attending the party with their children, please ask them to send a signed copy of the Release and Indemnity Agreement with their child.  Copies of the Release and Indemnity Agreement will also be available on the day of the party.

Will Thorne staff take photos?

Thorne staff might take photos during the birthday party.  Photos help us advertise our programs so we can reach more children through our work connecting kids to nature as a non-profit organization.  Please tell the instructor if anyone attending the party is not ok with having their picture taken.  We’d also really appreciate you tagging Thorne Nature Experience in any party photos you post on Facebook, Instagram or Twitter! 

What happens if it rains?

Thorne has an indoor space and can move parties indoors, as necessary.  We have backup rain plans and will also happily venture out into the rain with your group, if participants come prepared for the weather. Example indoor activities include: indoor games, reading nature stories in our bird nest library, scavenger hunts, or arts and crafts activities like building habitats, making insects, casting tracks, or creating seed necklaces.

How many kids can come to a birthday party?

Birthday parties are capped at twelve children because Thorne has found that twelve is the ideal number of children for one instructor to lead as a group and still deliver personalized attention to each child.  If you are considering growing your party beyond twelve participants, please be in communication with Thorne staff as soon as possible to see if a second instructor might be available. Plans to add a second instructor and grow party attendees past twelve children must be made at least two weeks in advance of the party date and cannot always be accommodated.
