Gateway Natural Area is the kind of place you will want to bring your family for a day in the mountains and definitely a place you will be proud to say is part of Fort Collins. Gateway Natural Area (formerly Gateway Mountain Park) is the site of the city's old water filtration plant, where the North Fork of the Poudre River joins the main Poudre River. Visitors enjoy it because its tucked away from the noise of Highway 14 and Gateway is only 15 miles from Fort Collins! You'll find hiking trails, a designated launch area for kayaks and canoes, fishing, picnic tables with grills, informational kiosks and a natural playground.

Due to safety concerns, walk-in access is not permitted along the paved entrance road.

Most of the materials for the natural playground were reused/ recycled or were found on site. Elements include stepping stumps, a rock streambed, a wooden boardwalk, a sandy area, a carved boat, a rustic log ladder, rock walls and a willow tunnel.


The Black Powder Trail is 0.8 miles and climbs steeply to an expansive view of the Poudre Canyon. The Overlook Trail is 0.3 miles and it climbs steeply to a beautiful ridgetop. Visitors also access City of Greeley's Seaman Reservoir through Gateway Natural Area. The reservoir is 1 mile from Gateway via a flat dirt road with a short climb at the end.

Swimming and cliff jumping are not permitted at Seaman ReservoirView the trail map.


Gateway Natural Area is open daily, dawn to dusk.

  • The daily parking fee of $7 is now being charged to everyone who enters Gateway Natural Area, including boaters and tubers putting in to the river.The fee is due to increased congestion in the launch area, maintenance and staffing costs, and to align with other agency’s practices.
