Normally following a handrail makes for easy navigation. However, even with a huge reliable feature like Georgian Bay to handrail beside, coasteering can still be tricky. This is because the coastline is crinkly with lots of parallel features. Those are bits of terrain that closely resemble the one you are looking for, in this case a peninsula pointing a bit West of North. Hugging the coastline the whole way is very slow with lots of extra distance and it becomes easy to lose track of how far you've gone. Distance tracking either via time or pace counting is much easier if you travel in straight lines. However, there are also almost no useful features inland to help teams stay in touch with the map or to use as waypoints. If they are not careful they may end up at the tip of what looks like the right peninsula with no CP in sight.
