Cascades Indoor Waterpark 2026 Schedule: Operating Hours, Holiday Rates, and Maintenance Updates
Cascades Indoor Waterpark adjusts its operating hours across three distinct seasonal phases. Operating hours are directly tied to regional school district calendars and Greek Peak lift operations.
During the core winter season running from January through March, the park operates daily. Monday through Thursday hours run from 11:00 AM to 7:00 PM, expanding on Friday from 11:00 AM to 9:00 PM. Saturday remains the flagship operational window, welcoming swimmers from 9:00 AM to 9:00 PM, while Sunday operates from 9:00 AM to 7:00 PM. During high-volume holiday windows, specifically Martin Luther King Jr. weekend, Presidents' Day week, and regional mid-February school recesses, the park defaults to full weekend hours across all seven days.
The spring and autumn shoulder seasons see a drastic reduction in facility hours. From late April through mid-June, and again from late September through mid-November, Cascades closes entirely on Tuesdays and Wednesdays for routine water treatment cycling and staff turnover. Thursday operating hours run from 4:00 PM to 8:00 PM, while Friday through Sunday returns to regular full-day schedules. The summer season, kicking off in late June, re-establishes daily 10:00 AM to 8:00 PM operations through Labor Day.
