The Geer Natural Area is named after Army Spc. George Raymond Geer, a local Cortez man killed in Iraq. It is on 60 acres of donated land in northern Cortez, Colorado, with groomed single track trails developed by the local Kokopelli Bike Club. Conveniently located right next to the Osprey offices on Alamosa street, the Geer Natural Area is only a five minute drive from downtown.

What Makes It Great

The city government and the local community have truly come together to build a great trail system in Cortez. Between the parks and recreation department and the tireless volunteers of the Kokopelli Bike Club, Cortez has once again proven its dedication to the development of the mountain biking community. At this newest trail system there are five loops named after Beatles songs, all connecting with each other, forming a total of nine miles of trail. There were bright new maps installed at all of the trail intersections, making it easy to navigate even for first time visitors.

It is an intentionally technical trail system, with many switchbacks rolling through the sage brush covered hills . The trail winds and curves quite a lot, often on short notice, so this is a great place to develop your technique and balance. Despite being crammed into a 60 acre lot, there is a lot of fun to be found in those nine miles of trail. There are a few sandy spots, but most of the trail is smooth, packed single track. It makes the Geer trail system a delight to have in town and a great place to blow off some steam.

Who is Going to Love It

If you need to do just that (blow off some steam), then Geer is an ideal destination. The fast paced single track is a great place to get in a quick workout. Because it’s so close to downtown, it makes a great place to come after work, or on a lunch break. If you are looking for a less crowded alternative to Phil’s World, then Geer is a great place to ride. The parking lot is rarely full, so anyone frustrated with the crowds at other local trails will love this trail system. Geer isn’t quite as glamorous as Phil’s World, but it certainly adds some diversity to the already impressive Cortez circuit. It can also be a great place for beginners to hone their skills. The tight corners and boulders make it a wonderful trail for practicing. Beginners who want to sharpen their gears on some challenging single track will certainly appreciate these trails. Visitors to the area will also enjoy Geer Natural Area. Because of it’s close proximity to many hotels, it makes a convenient location to enjoy the beautiful scenery of Southwest Colorado while first getting acquainted with the area.

Directions, Parking, & Regulations

The parking lot is located on County Road L (Alamosa Street) directly next to the Osprey offices. From downtown head East on Main Street towards Mancos, and make a left on North Mildred Road by the Cortez City Park. From there travel one and a half miles to Alamosa street and take a left, then you will see the entrance sign to Geer Natural Area a half mile down the road on the left hand side. This park is completely free and doesn’t necessarily require a map because the trails are so well marked. However, if you would really like a map, the latest edition of Big Loop Maps has Geer Park included.
