Tucked behind Westnedge Avenue's commercial strip is Portage's Millennium Park Ice Rink. This small outdoor rink is refrigerated so it stays frozen during West Michigan's winter thaws and it's lighted for night skating. It's open Wednesday-Sunday afternoons & evenings. (Open everyday during Winter vacation.)
It costs $4 to skate and skate rentals are $3. There's a small warming hut with benches & lockers and the rental office sells hot chocolate. Parking is behind Best Buy.
In the summer, the rink is a pond with a fountain.
830 Romence Rd (just west of the intersection of Romence and Westnedge.)
See the Portage Parks department for specific information on hours and on discounts for multiple visits. Update: Warm weather postponed the rink's planned opening. The rink is now expected to open by Dec. 15 for the 2012-13 season. It's scheduled to be open daily through December (closed Christmas.) Most days it's open 3-9. It will be open earlier on Saturdays (11 am) and Sundays (noon). In January and February, it will be closed Mondays and Tuesdays.
