Well Gulch is located in Lory State Park near the same area as the Arthur's Trail. It is a very easy alternative to the somewhat challenging Artur's Rock. The 1.2 mile loop trail sends hikers around a part of the park where many animals are seen. Well Gulch is a foot only trail, meaning that horseback riding and biking are both prohibited.  Well Gulch can also be taken to Timber Trail just 1.4 miles away.

Greyrock Mountain  is a trail located just past Ted's Place at the edge of the Poudre Canyon. The Greyrock Meadows Loop trail is a fairly strenuous 7.15 mile loop.

Because of the length, many people get lost along the trail, so be careful to stay on the designated path.

Along with Pingree Park located outside of Fort Collins, CSU also owns property within Fort Collins known as the Environmental Learning Center or ELC for short. The ELC is located off of Ziegler Road in between Drake and Timberline. Home to lots of Colorado wildlife, the ELC provides Fort Collins with a close connection to nature. Along with a network of trails throughout, the ELC, there is also an injured bird shelter with many recovering birds including a Bald Eagle, a few Golden Eagles, Vultures, Hawks and a few others. The best thing about the ELC is it is completely free to enter and explore.

Pingree Park is a large area of forest located about an hour and a half up the Poudre Canyon. Home to the CSU Mountain Campus and many campgrounds, Pingree is a great place for people who love the outdoors. Many hikes are available (although not all of them are completely mapped out so be careful not to get lost) all around the park. One hike is a trip through the forest to a B17 Bomber Plane that crashed there in 1943. If you are going to Pingree to camp, there are multiple campgrounds throughout the park that only charge a small fee to enter, and if you don't want to pay, there are tons of camping spots that are on the side of the road and don't require a pass to stay at. So if you have a weekend and want to get out of town, why not drive up to Pingree and check it out?
