Fishing around Willcox sits at the quieter end of Arizona's outdoor scene, which is part of the appeal. The options here split between lake fishing at Treasure Park and Riggs Lake and river fishing up at Upper Hospital Flat Group Site, giving you a reasonable range depending on whether you want to cast from a bank or work moving water. Treasure Park has two access points listed — North and East — so you can move around and find a less pressured spot without much effort. Riggs Lake sits up in the Pinaleno Mountains, meaning the drive involves elevation gain and the water runs cooler than what you'd find in the valley. Upper Hospital Flat is a group site, so it tends to see more traffic on weekends when parties are booked in, but midweek it can be genuinely quiet. None of these waters carry a gold-medal or wild-trout designation, so set expectations accordingly — this is solid local fishing, not a destination trophy fishery. That said, if you're staying in or near Willcox and want a half-day on the water without driving to the White Mountains proper, these spots cover the bases.
Frequently asked questions
What kind of fishing is available near Willcox?
You have lake fishing at Treasure Park (with North and East access points) and Riggs Lake, plus river fishing at Upper Hospital Flat Group Site. That covers still water and moving water within a reasonable drive of town.
Is Riggs Lake worth the drive from Willcox?
It depends on what you're after. Riggs Lake is up in the Pinaleno Mountains, so the road takes time and the conditions can be different from the valley floor — cooler water, cooler air. If you want a mountain lake setting and don't mind the climb, it's a more scenic option than Treasure Park.
When is the best time of day to fish Treasure Park?
Early morning before the heat builds is generally your best window for lake fishing in southern Arizona, especially in summer. The North and East access points let you shift position based on where shade and wind are working in your favor.
Can I fish Upper Hospital Flat as a solo angler or is it group-only?
Upper Hospital Flat is listed as a group site, which means it's primarily set up for organized parties. Solo or small-group anglers should check current site availability and any reservation requirements before making the trip out, since a booked group could limit your access to that stretch of water.
Do I need an Arizona fishing license for these spots?
Yes, a valid Arizona fishing license is required for anyone 10 years of age or older fishing any of these waters. Purchase one through the Arizona Game and Fish Department before you go — enforcement does happen at sites like these, including more remote ones.
