In British Columbia, many campgrounds operate on a first-come, first-served basis, where you don't need a reservation. Some options include:
1. Recreational Sites: Managed by Recreation Sites and Trails BC, these campgrounds are often more rustic and remote. You can find a list of these sites on their official website.
2. Provincial Parks: Some provincial parks have first-come, first-served campgrounds. Check the BC Parks website for details on specific parks.
3. Crown land: Dispersed camping is allowed on Crown land, which makes up approximately 94% of British Columbia. Keep in mind that there may be no facilities or services available, and you should follow Leave No Trace principles. Remember that popular areas can fill up quickly, especially during peak season, so it's always a good idea to arrive early or have a backup plan in case your desired campground is full.
