They may not be the best for exercise or for feeling like you’re alone in the wilderness, but I’m a huge fan of nature / interpretive trails. They’re accessible to a wide range of people and are great if you’re short on time, and often have a good sampling of the local flora. This is Bear at the Jane Rau Trail in February, I wanted to see how he’d do going over the bridge over the wash (he was unfazed). This loop is really short but a nice addition to the start or end of a longer hike and can offer up some pretty cool wildlife, I’ve seen a bobcat and a gila monster here.
