Long-time astronomy conference fans know the legend of Hidden Hollow as one of the friendliest and most comfortable conferences around. We’re nestled deep in the woods of Hidden Hollow resident camp in northeast Ohio near the town of Mansfield. Each year we provide some of the finest guest speakers available, and they join in the fun!

Most years, unlike other star parties, we provide cabins and bunkhouses for your comfort Unfortunately, this year due to Covid-19 restrictions, the cabins and showers will not be available to any attendees, be they Richland Astronomical Society members or our guests. We apologize for this late developing inconvenience, but we must abide by all the decisions made by The Friendly House, the owner of the camp and its facilities.

We will still have primitive/boondocking/dry camping sites for tent and RV camping, modern rest rooms and a licensed food service vendor available for lunch and dinner on Friday and breakfast, lunch and dinner on Saturday.

If it rains, it’s no problem. We have indoor facilities and all activities go on. There are warm areas where you can gather to converse, places to watch movies, play cards or just hang out. The observing field is well-drained and groomed with plenty of “space” to go around. This year we will be unveiling our new Stellina observation station, a telescope that sends “stacked” images from its live viewing field to 20 smart phones at once.

One of the most appealing parts about Hidden Hollow is the location itself. Even if you aren’t interested in staying up all night observing, you’ll fully appreciate the fine scenery of the camp itself. During the Fall season, Ohio offers some of the most spectacular foliage in the United States, and the pristine, quiet and peaceful surroundings of Hidden Hollow are an ideal place to relax and have an enjoyable weekend. There are plenty of trails to walk in the woods and nearby attractions, restaurants, hotels and shopping. Children and families are always welcome here!

Thanks to wide open spaces and peaceful seclusion, you’ll have a wonderful time at the Hidden Hollow Astronomy Conference. Our guests have voted us #1 as one of the most beautiful astronomical retreats in the country. During your weekend stay, you’ll be treated like family as you enjoy our workshops, contests, programs, fantastic prizes and observing. We welcome visitors of all ages, and you’ll find that no matter where you roam… There’s no place like our home in Hidden Hollow!
