This is my favorite hiking trail. You can take an easy trail and get a decent workout or move up to whatever level of difficulty you want. I have arthritis in my knees and lower spine, so some days I feel more adventurous than others. At Lost Dog Wash I can do whatever I'm feeling up to that day. The Taliesin Overlook is nice. Or you can really challenge yourself and go up the Quartz Trail or to Sunrise Peak and back. The views are never anything other than striking, and you end up feeling sorry for those poor bastards trapped down there in the smog of Downtown Phoenix, which is usually enveloped in a sad yellow haze. In Scottsdale you can leave all that behind and enjoy copious amounts of fresh air and gorgeous scenery. Do bring enough liquid refreshments to keep yourself and every living being in your party hydrated. Apparently a few dogs collapse due to lack of hydration every year. That wipes the smiles off everybody's faces, seeing someone's four-legged friend carted out in a wheelbarrow. With that caveat, enjoy!
