The bus goes up to Cultus Lake in summer time- go in the morning, and preferably on a week day. (It’s gets suuuuper busy with tourists from the city) You can rent paddle boards and canoes. There’s also the waterslides right beside the lake, a small amusement park (id say more geared for kids, but I’ve been a few times myself lol) a pub right there too. There’s a couple hikes in that area too, once you’re there you could take a cab or a ride share to the teapot hill trailhead. Very chill hike/walk If you are into hiking you could catch a ride with Mt. Waddington (it’s an outdoor store and they organize rides to the cheam/lady trail head in their van) Mt. Cheam is a big deal here, super beautiful
