Looks like I sync'd up with ChiefD on vacation schedules. I took a break from biking when we did our vacation last week. We were in Kauai and I did my fair share of hiking/walking. Being up 3 hours before the girls helped me fit a lot in. One hike that I've wanted to do for many years is the Kalalau trail which covers the NW coast of the island; only accessible by trail (viewable by boat). While I'd never be able to convince my wife and kids to do a 3 night, 25 mile overnight hike with camping, cliffs and no bathrooms, I was able to book passes to do the first part of the trail. Unfortunately, my younger daughter twisted her ankle the day before, so she wasn't ready to tackle the rocky trail, but older daughter and I did the Hanakapiai beach hike (the first 2 miles of Kalalau).
It was awesome and we got a really clear day. Definitely one of the better hikes I've done.
All the walking I did last week woke up my knee arthritis, but in a minor way. The resort we stayed it had bikes available for use, but I was good with sticking with walking and swimming to the bar for pina coladas if only for a week.
