Through a significant gift to the Ottawa County Parks Foundation from an anonymous foundation, the Grand Ravines Tree House will be constructed just off the Idema Explorers Trail route.The Tree House, which will be located high above the edge of ravine that parallels the north boundary of the park, will be dedicated to Bea Aldrink Idema in recognition of her love for nature, education, and having fun. The north ravines property is deeply connected to Bea and her family.

• The Grand Ravines Lodge which sits atop a ravine crest and overlooks the Grand River and is available to be reserved for private events. Please note: this facility was temporarily closed for COVID; it will re-open for reservations on April 8, 2021.
• The Idema Explorers Trail which traverses the edge of a ravine and features a dramatic descent from the top of the ravine to the river (and will eventually connect to Grand Haven to the west and Grand Rapids to the east), named for a $2 million gift from the Bill & Bea Idema Foundation
• A Nature Overlook, dedicated to the brothers and sisters of the John and Anna Aldrink Family, which provides a full view of the forested north ravine
• The 275’ Grand Ravines Suspension Bridge, constructed with a generous donation from Bea Aldrink Idema and dedicated to Ray and Alma Statema, floats 70’ above a ravine bottom on the south side of the park and has become an iconic feature of the West Michigan’s many parks (even being recently featured in a Grand Rapids-themed coloring book)

In 2018, the Michigan Recreation and Park Association (mParks) recognized the special natural features and amenities at Grand Ravines and awarded Ottawa County Parks & Recreation the Park Design award for that year. 

The Tree House complements these amenities and builds on them – the Tree House will stand 40’ above ravine edge where it starts to descend steeply to the creek bottom. To reach the Tree House, users will walk along a winding 100’ long boardwalk nestled among the towering trees. The enclosed Tree House will feature a rustic design with multiple overlook locations providing a unique tree-top perspective of the descending ravine.

The Tree House concept was first developed and proposed several years ago. “The Tree House design came from sketches sitting in the drawer of our Coordinator of Park Planning and Development, Curt TerHaar, that he first worked on in 2013,” said Ottawa County Parks Commission President Kelly Rice. “We are so appreciative of our donor and our Parks Foundation for allowing us to take a fanciful paper sketch from dream to reality. Through this generosity, future generations will have a unique and magical experience in the ravines.”

Engineering design on the Tree House is expected to commence in the Spring with construction hoped to begin later this year. As part of the project, expanded parking and supporting amenities will be added to the Grand Ravines Overlook parking area along the north entrance drive for Grand Ravines off 42nd Avenue.  

Additionally, work continues on the Idema Explorers Trail both east and west of Grand Ravines. Updates on the status of several segments of the trail could be provided over the course of spring and summer.
