Three Rivers Foundation and the Comanche Springs Astronomy Campus is proud to announce the Astronomy 101 offering.  This opportunity will be offered June 23 and June 24 2023.

Maybe you are a teacher looking for some 101 basics or a park ranger in need of instruction for your guests? This opportunity will be open to anyone aged 17+ and will be taught at a basic level so things are clear to understand and less confusing. No mathematical physics to worry about just basic Astronomy.

A $75.00 registration fee buys you into this wonderful learning opportunity and will include a tent site, RV site or bunk in one of our bunkhouses for both nights.


5 private cabins are available for an additional $300.  This covers two nights and the cabins include 2 full sized beds, private bath and kitchenette.  This is subject to availability and cabins will be reserved on a first come first served basis. 

An optional catered meal plan is available for $70 (Friday and Saturday, lunch and dinner only).
