San Isabel National Forest
Mt. Massive Wilderness Area

The Mount Massive Wilderness, encompassing 18,000 acres, was designated by Congress in 1980. The name comes from the second highest peak in Colorado, which has 7 summits over 14,000 ft. and truly lives up to its "Massive" name. With elevations between 9,700' and 14,300', much of the area is above timberline with alpine communities and a permanent snowfield.

Native greenback cutthroat trout have been recently reintroduced in the Rock Creek drainage, so fishing is limited to catch and release. This includes Native Lake. No special restrictions are in place for Windsor Lake.

• Permits: All profit and non-profit groups of 10 or more are required to obtain a special use permit through the local ranger district office in advance of their trip.
• Group Size: Group size is limited to 15. Stock groups are limited to 25 with a maximum of 15 people.
• Weather: Weather patterns change quickly. Warm sunny days can turn into powerful electrical storms. Be knowledgeable of the signs of change and be prepared for cold temperatures, rain, and snow.
• Trails: Please stay on the trails. Cutting switchbacks and avoiding wet and muddy sections can cause severe erosion and multiple paths. Peak climbers and cross-country travelers: Alpine tundra is very susceptible to damage. Walk on durable routes of rock or talus. In the spring, travel on snow and rocks, or plan your trip during drier conditions.
