Radium Lake is a 7.5 mile out and back trail located near Fraser Valley, British Columbia, Canada. The trail is primarily used for hiking and is accessible from July until October.
If starting from the Chilliwack Lake day use area, it's around 24km round trip. Trail is quite steep in some sections, especially towards the end. Surprised to see so many people hiking it in running shoes. The terrain is quite rugged towards the top. Proper boots will be beneficial. Also keep in mind the elevation, it can get cold at the lake even in summer months. We needed our jackets while eating lunch at the lake. Most people had nothing more than the t-shirt they hiked up in.
Next time we plan on doing this as an overnight to ensure we have enough time and energy to summit Mt. Webb
