How to book the Maple Bay cabins and group sites at Cultus Lake: the BC Parks booking windows, refund rules and how to catch a cancellation.
About the park
Cultus Lake Provincial Park is 11 km southwest of Chilliwack in the Fraser Valley, about an hour and a half's drive from Vancouver. You reach it via the Columbia Valley Highway: 10 km from Sardis or 16 km from the Yarrow entrance.
The lake is the attraction. BC Parks allows swimming only inside the buoyed areas (sandy beaches, steep drop-offs, no lifeguards, and swimmer's itch is possible), plus canoes, kayaks and paddleboards, water-skiing in a counter-clockwise direction only, and fishing for rainbow trout, cutthroat trout and Dolly Varden with a licence. There's a large day-use area for picnics and boating, wharfs at Entrance Bay and Maple Bay, and dog beach areas at both. Source: BC Parks: Cultus Lake Park.
Where to stay
Cultus Lake has four campgrounds: Delta Grove, Clear Creek, Entrance Bay and Maple Bay. It also has cabins and group sites. We watch:
The Cultus Lake Park cabins on Columbia Valley Highway are a different operation, run by the community of Cultus Lake and booked directly with them, not through BC Parks.
How booking works
Book on camping.bcparks.ca or through the call centre (7 am to 7 pm PT; phone bookings, changes and cancellations cost an extra $5).
- Cabins and campsites: BC Parks frontcountry stays open on a three-month rolling window at 7 am PT, covering the whole stay: for July 25 you book from 7 am PT on April 25. Long weekends release early on set dates; in 2026 they were February 15, April 1, April 30 and June 4, and 2027 is expected to follow a similar pattern, based on 2026. Check the cabin listing for any minimum stay. See frontcountry camping.
- Group sites: up to 12 months before arrival, paid in full up front and charged for at least 15 adults. See group camping.
- Stay limit: 14 nights per park per calendar year.
Last checked: October 2026.
When it books out
Cultus Lake is a summer-weekend park. With only 25 cabins, July and August weekends and the long weekends go fast once they open at 7 am PT. The four group sites, on a 12-month window, are often booked well ahead for summer. Midweek and shoulder-season dates are far easier.
Getting a cancelled spot
BC Parks' cancellation windows: campsites get a full refund of camping fees (less $6) if cancelled more than 7 days out, lose one night's fee within 7 days, and two nights on the arrival day. That page doesn't list a separate cabin rule, so check the terms when you book. Group sites refund camping fees only if cancelled 28 or more days out. Cancellations bunch up just before those deadlines.
Set a watch on the cabins or group sites with your first and last night, and Canada Camp Alerts will tell you when a fully booked night opens up. A night counts as open when any cabin (or any group site) is free; we don't match the same unit across nights, party size or accessibility, and we don't book or hold anything, so you book on camping.bcparks.ca. The free plan gives one watch with email alerts 15 minutes after we spot an opening; the season pass is C$25 once for 12 months, no auto-renew, with up to 10 watches and instant alerts by email, Telegram or web push.
