Day 1: Territorial Prison and Old Town
Start at Yuma Territorial Prison State Historic Park (220 N. Prison Hill Road), which preserves cellblocks and exhibits from the prison's 1876-to-1909 run -- the first seven inmates moved in on July 1, 1876, and the place operated 33 years before overcrowding closed it -- on a bluff above the Colorado River. Because the grounds are largely outdoors and exposed, go early rather than mid-afternoon, especially outside the cooler months. Then pair it with the old Quartermaster Depot grounds, now Colorado River State Historic Park at 201 N. 4th Avenue, which preserves five buildings from the U.S. Army supply depot established in 1864 and tells the story of the river crossing itself. (Older guidebooks call it Yuma Quartermaster Depot State Historic Park -- same place, current name.)
Check the day of the week before you build day one around these two. Arizona State Parks lists the prison as open seven days, 9 a.m. to 4:30 p.m. from October 1 through May 31 and 8:30 a.m. to 4 p.m. from June 1 through September 30. Colorado River State Historic Park runs a narrower week: Tuesday through Sunday from October 1 through May 31, and Thursday through Sunday only in summer. Both close for certain holidays. Confirm current hours with Arizona State Parks before you go.
Spend the rest of the afternoon in Old Town Yuma, the walkable historic downtown district near the river crossing. It's a reasonable place to look for a meal and get oriented before the more activity-heavy days ahead. See our full Territorial Prison guide for a deeper look at the site layout and how to plan the visit itself.
Day 2 Morning: The Colorado River and East Wetlands
Devote the morning of day two to the Colorado River corridor, which includes river-history parks, restored wetland areas generally referred to as the East Wetlands, and options for birding, walking, and paddling depending on current access and conditions. This stretch of river is central to what makes Yuma distinct from a typical desert highway stop -- a town genuinely built around a working river crossing.
Specific outfitters, rental options, and trail access points change over time, so check current listings before planning a river outing. Our dedicated river guide covers the parks and activities along this corridor in more depth.
Day 2 Afternoon: Agritourism, If You're Visiting in Season
If your trip falls in the winter growing season, spend the afternoon on a field tour through the region's lettuce farmland. This is not local boosterism: the USDA's Economic Research Service states that from mid-November through early April, most lettuce sold in the United States comes from the irrigated desert valleys of Southern California's Imperial County and the Yuma area of Arizona, with production shifting to central California from late April through mid-November. Field-to-fork agritourism experiences let visitors see that industry firsthand -- a genuinely distinct stop most first-time visitors don't expect from a desert border town.
Outside that window, the crop isn't in the ground and tours generally don't run, so swap this slot for additional time in Old Town or along the river instead. Check current operator schedules directly regardless of when you're visiting.
Day 3: Choose Your Day Trip
For day three, pick one day-trip destination rather than trying to cram in several. Kofa National Wildlife Refuge, north of Yuma off US 95, is a 665,400-acre U.S. Fish and Wildlife Service refuge -- more than 80 percent of it congressionally designated wilderness -- established in 1939 to protect desert bighorn sheep. The draw is Palm Canyon and its California fan palms, the only palm native to Arizona.
Set your expectations correctly here, because the name oversells the walk and undersells the drive. The Fish and Wildlife Service lists the Palm Canyon Trail at about 0.45 miles, ending at a sign where you look up into a north-trending side canyon to spot the palms. Actually scrambling up to the trees is a different proposition: the refuge's own trail guide calls it "a very rugged, difficult climb" and says to allow an extra 30 to 40 minutes up and back. What makes this a full day is the driving, not the hiking. The refuge warns that most of its roads need a high-clearance or four-wheel-drive vehicle, that there is no drinking water, fuel, or towing anywhere on the refuge, and that cell coverage is absent across most of it -- so top off the tank, carry far more water than you think you need, and tell someone your route and expected return. Call the refuge for current road conditions before heading out.
Alternatively, Los Algodones just across the border offers a shorter, more logistics-heavy day focused on the cross-border experience itself. Get the documents right before you commit: to re-enter the United States at a land border, U.S. Customs and Border Protection accepts a U.S. passport book, a passport card, an enhanced driver's license, or a Trusted Traveler card such as SENTRI, NEXUS or FAST -- the passport card and enhanced license are valid by land but not for international air travel. U.S. and Canadian citizen children under 16 need only proof of citizenship, such as a birth certificate. Check current CBP guidance and border wait times before you go. Our Kofa and Los Algodones guides both go deeper into planning either option.
Where to Base Yourself and Getting Around
For an itinerary structured this way, a base near the I-8 corridor or Old Town keeps day one walkable and puts you within a reasonable drive of the river parks and both day-trip options. A car is effectively required for this plan -- the river parks, the agritourism stops, and both day-trip destinations are outside easy walking distance. Yuma County does run a public bus system, YCAT, covering Yuma, Fortuna Foothills, San Luis, Somerton, Wellton, the Cocopah and Quechan Fort Yuma reservations and on into California, but it operates Monday through Saturday and is built for residents rather than visitor itineraries, and it does not reach Kofa.
If you're visiting during snowbird season, book lodging well ahead, since the winter months are Yuma's busiest travel period. See our RV parks and snowbird guide for more on how that season works.
Making the Itinerary Flexible
This plan assumes a November-through-March visit, when the outdoor stops are more comfortable and agritourism is actually running. If you're visiting in summer, keep the same rough structure but front-load outdoor time into early mornings, treat the afternoons as indoor or rest time, and drop the agritourism stop from day two since it won't be available. Whatever the season, always check current hours and conditions for each stop before you go, since details change.
