Sabino Canyon offers many beautiful hikes but I've only hiked the Seven Falls trail --twice. Once in the spring & the 2nd time just this past weekend. Early spring is the best time to go --the falls are actually flowing. When we went over the weekend, it was more like Seven Trickles than Seven Falls. This is still exciting for Tucson though! From the visitor center, the hike is about 8.8 miles round trip (I'm including the 1/2 mile to the trail head). You can opt to take the tram to the trail head for a fee. The hike itself is relatively easy & flat until about the last mile close to the falls where the trail ascends & descends over rocks. The views are beautiful & well worth the 2-3 hours (if going at a leisurely pace). It's also nice to either take a dip in the falls or just get your feet wet. At this time of the year, all we did was dip our feet since there wasn't much water. When we went during the spring, there was enough water for swimming. A couple things to note: dogs aren't allowed, there is a $5 parking fee, moderate traffic on the trail, flushing bathrooms near the trail head.
