That would be on foot, mostly.
It was a 2 mile bike ride in on flat surface at which point we ditched the bikes and started hiking. We spent the next 3.5 miles on trail and then switched to literally creek-hopping for the next 6,000 miles or so (or so it seemed).
To make a long story short, it's lucky I got home last night without spending the night in the forest. I'm an accomplished/avid hiker, backpacker and geocacher but I did a poor job planning this hike and was relying on others that "said" they knew what they were doing. Turns out they had been on 80% of the route and assumed we could shortcut the last part off trail and losing 1,600 feet of elevation.
We ended up doing it in the dark and I had to lead the group out via GPS/topo map with 4 headlamps in a group of 7 people. Not good. Sheer drops and unsure footing almost caused us to camp out last night and by the time I got home I was pissed. At the group leader for not being upfront about not doing this route before, and at myself for not knowing better and taking responsibility for my own safety.
I know this park and knew the route he proposed as I'd been on 75% of the trails before but it was the last 25% that I relied on somebody else for. Honestly, we got lucky that we didn't spend the night out there as a result.
It's a good reminder about preparedness and personal responsibility. Most stories you hear about missing hikers start with, "he/she is an accomplished hiker...." and now I know how they get in trouble. Just one bad decision or a series of small bad decisions makes the difference. Tonight, I needed a full bomber of this to just chill. I've shared my post-hike thoughts on our local forum as "lessons learned".
