What to see
A note to organizations/child care centers that would like to bring a group of more than 12 people to the Preserve
We do our best to accommodate a variety of groups and programs at the Preserve, but are limited by these guidelines:
- Our primary mission is to preserve habitats, plants and animals indigenous to West Michigan. Therefore, a policy is in place to limit the number of Preserve visitors per day, trails are for walking (the preserve is not a sporting area), and picnicking is not permitted.
- The Preserve is used for many different purposes at various times of the week (particularly for camps during the summer), therefore, we schedule its usage to avoid overlapping large group visits.
For groups larger than 12, we request you schedule an educational program with us; please contact Julie Wilbourn. There is limited availability for these programs in the summer, so we suggest you contact us as early as March to reserve a time during June–August.
