Deeks Lake is a challenging 9.1-mile out-and-back trail in Cypress Provincial Park, British Columbia, Canada. The trail starts off with some gradual elevation gain through a lovely forest, passing by several viewpoints and waterfalls along the way. The last two kilometers get steeper, so be prepared for a bit of a workout. The lake at the end is a beautiful reward for your efforts, perfect for a refreshing swim on a hot day. Just watch out for those pesky horseflies and blackflies buzzing around the shore!
