Last month, a friend and I decided to explore Bert Flinn Park in Port Moody. There are numerous trails within the park, so you can spend hours walking in the park (we spent about 2.5 hours at a leisurely pace, exploring various trails). The trails are flat with little to no elevation, so you won't be hiking, but it's still a lovely park for walking. There are several biking trails, so be careful if walking along a biking trail.
The park is transit accessible and we took the #183 bus from Moody Center Station and got off at Heritage Mountain Boulevard @1200 block and walked a few minutes to the entrance at Heritage Mountain and David Avenue.
Overall, a lovely park for a walk, but not for hiking. As it takes me over an hour by transit to get there and there is no elevation for hiking, it's unlikely I will make the trip again. But it is a nice park for a walk, and if I lived in the area or if I find myself nearby again, I would go for a walk.
Note: there did not appear to be any washrooms/outhouses, so we had to pee in the woods.
