The Portneuf Valley Environmental Fair is an annual event dedicated to inspiring wonder and appreciation of the natural world we live in, providing environmental education, and bringing the Portneuf Valley community together in the spirit of Earth Day.

First launched as an environmental awareness event in the United States on April 22, 1970, Earth Day is celebrated as the birth of the environmental movement. It is our goal to keep our community informed of the important environmental issues which impact us and our and quality of life, while empowering everyone to take action, make informed decisions, and appreciate the beauty of the Portneuf Valley.

In 2025, the Portneuf Valley Environmental Fair will be held at the end of Earth Week on Saturday, April 26th, at Lookout Point from 11 a.m. to 3 p.m. On average, over 5,000 people attend this free event. Over 70 local businesses, agencies, and organizations will host hands-on activities for children of all ages, provide giveaways, and teach everyone how to protect the Portneuf Valley for current and future generations. FREE admission, FREE food, LIVE music, and FREE bus rides from Pocatello Regional Transit to the event make coming to the Fair a no-brainer. We have something for everyone, so bring your friends and family for a fun-filled afternoon in the park!
