Powderhorn Park was scooped out like a bowl at the start of the 20th century, which means that today its steep sides are ideal territory for log-rolling, hill-sprinting, and above all, sledding. Because there's not just one prime incline, the slopes rarely get overcrowded, and the park's sledding crowd tends to include plenty of kids-at-heart jumping on their toboggans, and creative sled-makers showing off their flair in preparation for the annual Powderhorn Art Sled Rally. For some in the over-10 crowd, the thrill of sledding can wear off after a few trips down the hill (or when their cardboard box begins to shred at the seams). In those cases, the warming hut next to the lake has free skates for continuing the outdoor fun. An equally valid choice: claiming your activity fix and heading next door to Mayday Café for a heaping bowl (yes, bowl) of hot chocolate.
