Groups and Retreats at Winthrop / N. Cascades National Park KOA Holiday

Group Reservations

We welcome groups! A group is 3 or more site reservation requesting to be together. We can create any combination of sites that fit your group needs. We have Full Hookup (Water, Electric, and Sewer), Water and Electric only, and tent sites available, along with deluxe and rustic cabins. Our Pavilion has an electric cook-top, 2 sinks areas for dishes, and seating for 30 - 40 people.

To reserve, you can either create a block of reservations and have your people call in their deposits or everyone book their sites online. If you decide to book online please make sure your group selects the same type of site and puts in reservation notes about being in a group or uses the "KOA Select My Site" option. It is advisable to get group reservations booked and organized a minimum of 6 months in advance as certain dates are very popular, with holidays booking a year in advance. See our campground map for site locations. We look forward to hosting your group!
