Gateway Natural Area is a great park that is a close drive from Fort Collins but feels more remote. The trail to Seaman Reservoir is a pleasant, if uneventful walk up a gravel path/road to a rocky trail. Nice views when you get up to the reservoir. Don't go in the water near the dam, as the dam creates strong undercurrents and is extremely dangerous. Travel out the same trail you came in on.
