This is a very nice linear park in the downtown historic district of Yuma. Facilities include a picnic area with grills, fishing pier, playground, beach and restrooms. Parking is free. We stayed at the Garden Inn adjacent to the park and were able to walk the paved trail along the river to the Colorado River State Historic Park and to restaurants on Main St. There is a restored vintage steam locomotive on display next to the hotel and also several small museums nearby in the downtown area such as Sanguinetti House and Yuma History Museum. Gateway Park connects to East and West Wetland Parks so it's possible to walk a couple of miles along the river. Wheelchair access is very good. The Territorial Prison Historic Park is just east of Gateway Park and within walking distance for some people, but the trail was uphill and not paved. We wanted to walk the whole distance of the river trail but it started raining so we had to cut it short. We enjoyed it and would like to return soon.

Very relaxing walk in both the east and west directions. Very well maintained, not trashy. Some wildlife, although not a lot. You can watch the long trains traverse the high bridge and wave to the engineer. There are informative signs along the pathways, and even a small beach if you want to swim under the bridge.

We traveled to Yuma in an RV and found this park to be a good spot to stop and plan our sightseeing adventure. We had no problems with any of the people in the park, even meeting some fellow RV's who were doing the same as us. The prison is right across the road (altho I recommend driving there) Nice view of the "Ocean to Ocean bridge. A nice shady spot to park while walking through down town (Don't miss the story about the plane & car in city hall!) also pivot point is just a short walk away. Again, we found this a nice place to stop and plan that (and the next day's adventure)
