Houston Trail is a 4 km loop just outside of Fort Langley in Derby Reach. Once there, it is well marked & maintained. It is a perfect walk that almost feels like your hiking. It has lots of rolling hills and a few views of the lake popping through.
If you start to the left on the way back you will climb a steep hill. I like to do it twice, starting to the left the first time and the second time the right. It is quite busy and popular with limited parking. There is a brochure giving you more information about all the trails around Derby Reach at the beginning of the hike. Happy Trails!
