The City Creek trail system starts just a block or two from downtown Pocatello and climbs up the mountain hillside a variety of ways. The trails are mostly loose dirt or gravel which can make it treacherous with too much rain. It seems like most people who show up are either biking or jogging for exercise, but you'll see people cruising the trail on occasion too. It's so close to town, if you're in Pocatello it's really a must because there is basically nothing else to do in Pocatello anyway. That said, the trail system is actually really cool and definitely worth a stop.
