Mar. 15 All trails open for hiking and dog walking. Many of the trails are wet and mushy after all the rain we have had. Now that chances of snow and groomed Fat Bike trails are bleak, we will not longer be offering Fat Bike rentals this season. When trail conditions get better you can still bring your own Fat Bikes out on the bike trails. Be on the lookout this fall for more opportunities to rent Fat Bikes provided by Outpost Sports. Nature Center Building Hours: Wed - Fri 10 a.m. - 5 p.m. Closed Monday - Tuesday. Trails open daily.
