We invite Friends of the Clifton Institute to come explore the field station on their own every Saturday from mid-January to mid-October. You can become a Friend of Clifton with a minimum annual donation of $40. Your support will help us reach our goals of expanding and improving our education, restoration, and research programs this year. Thank you!
Before attending an open-access day, please read the information included on our liability release form (click here). As you walk our trails, you can help us take care of the field station by keeping your eyes and ears open to help us learn about the ecosystem we’re a part of and by enjoying and respecting the plants and animals that live here.

A trail map is available here. Please note that some trails are in the process of being built and many are not marked. Navigation skills and a GPS are recommended. Please stay on the trails, use common sense, and proceed at your own risk.
The farmhouse is closed to all visitors at this time. There are port-a-potties available in both parking lots.
We reserve the right to deny access to our property to anyone who does not obey the rules posted below or is otherwise disruptive to our field station operations.

On open-access days, you may park either at the lower parking area (“the Gap”) or at the farm house.
All children under the age of 18 must be accompanied by an adult.
You are welcome to bring your family with you on open-access days. One or two visitors are acceptable as well, but if this starts to be abused we reserve the right to limit the benefit to family members.
No dogs are permitted.
Leave no trace. We expect you to take all litter with you. It would be even better if you helped us pick up any litter you find! We do not have trash collection facilities.
Take nothing but photographs. We use our trails to teach kids about the environment and their experiences are much richer if there are still feathers and bones and everything else for them to look at.
No swimming, fishing, boating, or any other entry in the ponds.
No alcohol is permitted.
No horses, bicycles, automobiles, ATVs, or any other vehicles are allowed on the trails.
No hunting is permitted.

When you register below, please register and pay for the number of children you expect to participate in the class each month! You can think about this through the lens of: will my child want to use the materials that they see the other kids using (magnifying lenses, eye droppers, stuffies)?

No refunds will be given upon registrant cancellation within 1 month of the program’s start date. No refunds will be given for any missed programs. You will be sent a liability waiver and medical form before the start of the program.
We look forward to seeing you at the Clifton Institute!

Nature Club 2025-26
2025-09-13 13:00 - 15:30
Nature Club is a program where middle and high school students who are interested in the natural world can spend time in a nerd-friendly environment. If they like bones, insects, tools, plants, fungi, research, or simply to be outdoors, then they have found their people.
The club generally meets on the second Saturday of every month throughout the school year. In the 2025-26 year, we will be focusing on the three tenets of our work at Clifton: Research, Restoration, and Education. Members will help various Clifton staff and visiting professionals from other local organizations with what they do around the field station: propagating plants, building structures, removing invasive species, studying plants and animals, and making educational materials. There will be a chance for students to share their experience with their families at the final party in May!
Nature Club meets from 1-3:30 PM on the following dates: September 13, October 4*, November 8, December 13, January 10, February 14, March 14, April 18*, May 9.
Scholarship Opportunity: We have 5 full merit-based scholarships available. To apply, please fill out our Scholarship Application Google Form by September 5th, 2025.

Warning: You MIGHT be encouraged to participate in a sing-along.

Fall Native Plant Sale
2025-09-20 10:00 - 13:00
Native plants provide better food for insects, which in turn provide food for birds. You can make a huge difference for wildlife by planting native species on your property. Since fall 2019 we have been collecting seeds of native grassland plants from around the area, which means in addition to being native they are of local ecotypes. At the plant sale we will sell seedlings grown from these seeds of a variety of perennial wildflowers, native grasses, and a few trees. Some of our favorites include butterflyweed, upland ironweed, scaly blazing star, narrow-leaf mountain-mint, and gray goldenrod. Partners from other organizations will also have plants and merchandise for sale. We will accept credit card, cash, or checks made out to the Clifton Institute. We hope to see you there!
Weather policy: Rain or shine except in case of extreme weather (e.g. thunderstorm or significant snow fall).

We are so grateful for our volunteers’ help and support. We could not accomplish our mission without you! We would like to thank you by hosting you and your families for an evening at the Clifton Institute. This will be a very casual event. We will provide food and drinks from a local barbecue restaurant. All you need to bring is yourself! You’re welcome to arrive before 5:30 and hang out on the lawn or go for a walk if that makes coming after work easier.
Please RSVP so we know about how much food to order. If you have dietary restrictions you would like us to take into account please email kpaulsen@cliftoninstitute.org at least a week before the event date.
