Rainbow Park Boat Ramp in Oshkosh is one of the busiest and most-used boat launch facilities in the city, featuring multiple launch areas with long piers and ample parking (52 vehicle spaces and 37 boat/trailer spaces).

The facility offers amenities including picnic areas, shelters, restrooms, and an accessible canoe/kayak launch, though visitors should plan to arrive on weekdays to avoid crowded conditions, especially during peak fishing seasons and tournaments.

A day-use fee is required for boat launching, and the ramp accepts credit card payments.
