Year-Round Drop-In Day Camp and Activity Center

the conscientious alternative for kids age 6 to adult

After 20 years and twenty thousand children at the Seaplane site

Constant pursuit of child-advocacy has made The Planet unlike any ‘program,’ but very like an ideal neighborhood or village. While ‘Planet kids’ are free to do nothing, they choose to spend most of their time in our highly-structured Beading-Sewing and Handtool-Woodshop classes – the best in the world. This ‘interest-based learning’ lets children focus their attention beautifully, as they happily build the mental systems of logic and math. And that close structure is complemented by the delicate supervision which fosters priceless, old-fashioned, kid-generated ‘play’ – a value we’ve upheld for decades and is now widely seen as sadly lacking in most kids’ lives. Come see these living realities!



We will be open January 19th and 20th from 8:30 am to 6 pm

February 16-20th  8:30 am to 6 pm

April 13th-17th 8:30 am to 6 pm



Starting September 12, The Planet will be open at noon every Friday, to accommodate home-school families, with children 5-1/2 or older.

All you have to do is show up. The kids can start right away. You’re welcome to stay after our normal opening hour, 3:00. The Planet closes at 6:00.

Our cost for homeschoolers is always our lowest rate – $9/hr – any time The Planet is open – without the usual requirement of buying a 30-hr block.
