The track mapped here is just one loop you could make, out of many possibilities. It follows the mellow Harrison Hollow Trail uphill, then climbs more steeply to Kemper's Ridge. On the ridge, you'll encounter some seriously steep sections, but also find phenomenal views over the city and up to the mountains.

The lower and flatter trails, like Harrison Hollow, are good in any weather, but you'll want dry conditions for the trails higher in the hills. They get very slick, and they are easily damaged when muddy.
