Most campgrounds in the tri-state corner where Wisconsin, Iowa, and Illinois meet run a warm-season calendar: open in April, closed by mid- to late October. If you need to camp through a Mississippi River Valley winter, your options narrow to a short list of parks that keep their gates open all year. This page lays out which ones actually stay open through the cold months near Hazel Green, what trade-offs come with winter camping here, and which park is the strongest pick once the weather warms up.
Honest framing matters here. Coconut Cove RV Resort by RJourney, the destination property in Hazel Green, is a seasonal resort: it runs April 15 through October 15 and closes for the winter. So if you need a site in January, Coconut Cove is not your answer, and we will not pretend it is. We point you to the genuinely year-round options nearby (Swiss Valley near Dubuque and Creek Valley), and explain why Coconut Cove is still the park to build your warm-season trip around.
Year-Round vs. Seasonal Camping Near Hazel Green
What "Year-Round" Actually Means Here
The tri-state Mississippi River Valley runs a short camping calendar. Most private resorts and the area’s Corps of Engineers river parks (Grant River, Blanding Landing) open in spring and close by mid- to late October. Genuinely year-round sites, the kind you can pull into in January, are a small minority near Hazel Green, and they typically trade resort amenities for the simple fact of staying open. If you want to camp through the winter, your realistic options are the two parks in the competitors section below: Swiss Valley Campground near Dubuque and Creek Valley Campground.
Coconut Cove Is the Warm-Season Pick, Not a Winter Park
Coconut Cove RV Resort by RJourney is the most full-featured park in the Hazel Green area, but it is seasonal: April 15 through October 15, then closed for winter. We will not pretend otherwise. If your trip lands inside that window, Coconut Cove is the park to build around: full hookups, a floating water park on a 13-acre lake, an on-site restaurant and tiki bar, live weekend bands, and cabins and pods. If you need a site outside that window, book one of the year-round parks below and put Coconut Cove on the calendar for next summer.
Cold-Weather Camping Realities
Winter RV camping in the Upper Mississippi Valley means planning for it. Year-round parks here often run water to the bathhouse rather than to individual sites once temperatures drop, so you may be relying on holding tanks and a heated water hose, or hauling water. Swiss Valley, for example, allows winter camping but turns off site water hookups in the cold months. Skirting your rig, managing your furnace and propane, and keeping tanks from freezing all matter at these latitudes. Call any year-round park before you arrive in the cold months to confirm exactly which utilities are live for the season.

Coconut Cove RV Resort by RJourney
Coconut Cove RV Resort by RJourney sits at 1549 Bluff Rd in Hazel Green, Wisconsin, where Wisconsin, Iowa, and Illinois meet above the Mississippi River. Downtown Dubuque is minutes south and downtown Galena is minutes east. The resort wraps a 13-acre lake with a floating water park as the centerpiece, surrounded by full hookup RV sites, 10 cabins, and 4 glamping pods, plus a full-service restaurant (The Clubhouse), a tiki-themed poolside bar, and live weekend bands. One thing to know up front: this is a seasonal resort. It runs April 15 through October 15 and closes for the winter, so it is not a year-round option. What it is is the warm-season anchor for the area, the destination stay when your trip lands inside that window. For winter camping, see the year-round parks listed below.
Sites & Hookups
During the open season, RV sites come with full hookups: water, sewer, and 30/50-amp electric, in both pull-through and back-in configurations, each with a picnic table. Because every site has its own full sewer hookup, there is no separate dump station on the grounds (if you need dump service, it is $50 to use an available site). Tent and car camping are not permitted here; this is an RV, cabin, and pod resort. For guests who want the resort without towing a rig, 10 cabins and 4 glamping pods put you steps from the water park and lake. Extended-stay and monthly options (starting at $900/month) work for seasonal campers locking in for the summer.
One honest note for trip planning: these full hookup sites run April 15 through October 15, not in winter. If you need a site in the cold months, the year-round parks in the competitors section below are your move, with the understanding that they typically run electric-only and shut off individual-site water once it freezes.
What's On-Site
The centerpiece is a floating water park on the 13-acre lake: inflatable obstacles, slides, splash zones, and open swimming. A swimming pool sits at the heart of the resort, ringed by lounge chairs and the poolside tiki bar. The Clubhouse serves lunch and dinner, the Coconut Cove Bar runs tiki drinks poolside, and on weekends live bands take over the pool deck. Beyond the water there is lake fishing, kayak and paddleboard rentals, morning yoga, golf cart cruising, outdoor movie nights, a jumping pillow, a sand beach, and a playground. Practical amenities cover a 24-hour laundromat, ADA-accessible facilities, showers, a fenced dog park, propane sales, and a camp store. All of it runs during the open season, April 15 through October 15. Note: water park access requires a wristband purchased separately from your site reservation; call (608) 716-7933 to confirm current rates before you arrive.
What Guests Say
Coconut Cove holds a 3.8-star rating across 507 verified Google reviews. The consistent positive themes: the water park is the draw families drive hours for, the food and drinks from The Clubhouse and the tiki bar come up again and again as a real convenience, and the staff get repeated mention for going out of their way. Seasonal campers point to the resort-style atmosphere, the 13-acre lake, and the community feel that builds over a summer. The critical themes worth flagging for honest expectation-setting: add-on costs that were not obvious at booking (water park wristbands, extra-guest fees) have surprised some guests, and pool and beach crowding on peak weekends comes up. Our recommendation: call (608) 716-7933 before you arrive for a full cost breakdown so your total spend matches your expectations.

Things to Do Near Hazel Green, WI
The Mississippi River defines the western edge of the tri-state area, with bluffs, scenic overlooks, and backwater channels running for miles. Fishing targets walleye, catfish, sauger, and panfish, and boat launches dot the shoreline from Potosi to Dubuque. In the warm months, Coconut Cove’s 13-acre lake adds kayak and paddleboard rentals, a sand beach, and the floating water park. Spring-fed Catfish Creek at Swiss Valley runs cold enough for stocked trout into the shoulder seasons.
The tri-state area has more trail access than most visitors expect, and much of it stays open through winter. The Heritage Trail in Dubuque County runs 26 miles along a converted rail bed. Mines of Spain Recreation Area south of Dubuque covers 1,400 acres of bluffs, prairies, and forest with Mississippi overlooks and winter hiking, and the Swiss Valley Nature Preserve offers groomed cross-country ski trails when snow falls. Horseshoe Mound Preserve near Galena delivers one of the best three-state views in the region.
Downtown Dubuque, Iowa is minutes away and home to the National Mississippi River Museum and Aquarium and the Fenelon Place Elevator, the world’s shortest, steepest scenic railway, both open year-round. Downtown Galena, Illinois is one of the most photographed small towns in the Midwest, with an entire Main Street of 1800s brick buildings full of boutiques, wine rooms, and restaurants, plus the Ulysses S. Grant Home. Galena leans into holiday shopping through the winter, making it a strong cold-weather day trip from any year-round campsite.
Seasonal Guide for RV Travelers Near Hazel Green
Summer (June through August)
Peak season and the heart of Coconut Cove’s calendar. The floating water park runs full-time, live bands play every weekend, and the regional calendar fills with the Galena Balloon Race, county fairs, and rodeos. Daytime highs reach the 80s and 90s. Book 3 to 4 weeks ahead for weekend stays, especially around the Fourth of July.
Fall (September through mid-October)
Fall color along the Mississippi bluffs is spectacular. Crowds thin and weekday availability opens up while Coconut Cove’s restaurant and bar keep operating toward the October 15 close. Temperatures cool into the 50s and 60s, ideal for hiking the bluff trails before the seasonal parks shut for winter.
Winter (mid-October through March)
Coconut Cove and the area’s river parks are closed. Year-round camping near Hazel Green means Swiss Valley near Dubuque or Creek Valley, with reduced utilities and cold-weather setup. Galena and Dubuque stay busy for holiday shopping, indoor museums, and breweries, and the Swiss Valley preserve opens up for cross-country skiing and snowshoeing.
Spring (April through May)
Seasonal parks reopen, typically mid-April. Coconut Cove’s season starts April 15. Cool, variable weather warming through May, with the water park and pool coming online as temperatures hold. A good window to explore Dubuque and Galena before the summer crowds.
Practical Tips for RV Travelers Near Hazel Green
Coconut Cove and most area parks run April 15 through October 15. If your trip falls in that window, book Coconut Cove. For mid-October through March, use a year-round park like Swiss Valley or Creek Valley instead.
