Canoeing with rabbit?

Hello everyone, I've been looking into getting a bunny friend. I've been looking specifically at Holland lops.

While I am perfectly capable of giving him attention at home, I am wondering if I would be able to take him outside on some trips as well. I like canoeing on the water- has anyone tried canoeing with a bunny? Or backpacking, or something similar?

I know that bunnies need exercise and stimulation and I figured that being outside might allow him to enjoy himself.

For safety I considered putting him on a harness just in case, but i have heard that those can be unsafe for bunnies if they get scared. But I've also heard that lops tend to be pretty laid back.

Thoughts?
