June 12, 2025, Sulphur Spring Cave

Sulphur Cave has a temperature: of 73Β°F. According to the sign, this is the most mysterious of the springs. Legend has it that the early Indians used this cave and its springs during rituals. Oracles in similar sites throughout the world have prophesied future events after being mesmerized by sulphur vapors. The geologic features of this cave are particularly unique, displaying the strength of the springs as they travel upward through the porous rock. There is a significant amount of bacterial/algae growth called myceum, the original life form dating back 4 billion years. No entry.

The Spring Creek Trail is a mix of single- and doubletrack dirt β€” great for straightforward running. You'll share the trail with hikers and mountain bikers, although some of the mountain bikers may be off enjoying the big jumps of the Spring Roll Trail, which parallels this stretch of the Spring Creek Trail.

Although the parking lot is quite big, the trailhead fills up quickly especially when the aspens shimmer golden in late September. Check this webcam before you drive up to the Dry Lake Trailhead to find out if there are still lots available: share.earthcam.net/tJ90CoLmq7TzrY396Yd88PN-LGPG_7LcFwWSD6ItD3c!/steamboat_usda_forest_service_dry_lake_trailhead/camera/view_1 .

November 11, 2023, Encampment River Trail

This section of the Encampment River Trail follows the river to the northern boundary of the Encampment River Wilderness/Medicine Bow-Routt National Forest. You could keep running, if you like, and complete more than a marathon in round-trip distance before reaching the last trailhead. With that said, keep an eye out for reports of downed trees, which are common along this trail. It's nice to know whether you're in for a pleasant trail run or a steeplechase.

November 7, 2023, Gilpin Lake

This beautiful, 29-acre lake is one of the most popular destinations in the Mount Zirkel Wilderness and part of the "Zirkel Circle," a loop that also encompasses Gold Creek Lake. The trail itself is heavily forested for much of its length and, although you may not get much solitude here, the beauty is worth braving some crowds for.
