Most campgrounds in central Pennsylvania shut the gate after leaf season and reopen in spring. If you are looking for an RV park near Northumberland that keeps long-term sites running through the cold months, the list is short, so it pays to confirm what is actually open before you point the rig north.
Northumberland sits where the West Branch and North Branch of the Susquehanna River converge, about 440 feet above sea level in the Susquehanna Valley. Winters here are real: cold snaps, occasional snow, and short days from December through February. For RVers, that means a year-round stay is as much about hookups, skirting, and heat management as it is about location. Here is an honest look at what year-round and extended-stay RV camping near Northumberland looks like, starting with the confirmed winter monthly option at Splash Magic Campground by RJourney.
What Year-Round RV Camping Near Northumberland Really Looks Like
What Is Confirmed Open Off-Season
The honest answer matters more than the marketing one here. At Splash Magic, the confirmed cold-weather program is the winter monthly site at $600/month, September through April. That is a genuine extended-stay option for seasonal workers and snowbirds. The summer water park and the bulk of the activity calendar are seasonal and do not run in winter. Before booking a winter stay, confirm with the office which facilities (office hours, restrooms, laundry, camp store) stay open through the coldest months versus close for the season.
Winterizing for a Susquehanna Valley Stay
Northumberland winters bring cold snaps, occasional snow, and short days. If you plan to stay on-site through winter, the full-hookup sites with 30/50-amp service give you what you need, but skirting, a heated water hose, and tank heat management make the difference between comfortable and miserable. Plan your power draw around 50-amp service if you are running electric heat, and keep an eye on overnight lows from December through February.
Who a Year-Round Site Works For
The winter monthly rate fits two profiles best: workforce travelers on multi-month assignments in the Sunbury and Northumberland area, and snowbirds who want an affordable, full-hookup base to break up a trip south. If your goal is recreation, the off-season is quiet by design; if your goal is a practical, low-cost home base near the Susquehanna with river access and a camp store, it earns its keep.

Splash Magic Campground by RJourney
Splash Magic Campground by RJourney sits at 213 Aspen Lane in Northumberland, along the Susquehanna River where the West Branch and North Branch meet. The property is best known for its summer water park, but for extended-stay and cold-weather RVers the relevant fact is its winter monthly program: long-term sites run $600/month from September through April, which makes it a practical base for seasonal workers and snowbirds breaking up the trip south. Sites are full hookup with 30-amp and 50-amp service in both pull-through and back-in configurations. Whether the office, amenities, and transient sites stay open the full calendar year is worth confirming directly with the park before you book a winter stay, since the summer water park and activity calendar are seasonal.
Sites & Hookups
Splash Magic offers full-hookup RV sites in both pull-through and back-in configurations, with 30-amp and 50-amp electrical service for rigs of any size. For cold-weather stays, the winter monthly rate runs $600/month from September through April, which is the property’s confirmed year-round-style program. Tent sites are available in season for guests who prefer to keep it simple. Each RV site includes parking for two vehicles; overflow parking is available at $10/day near the lakeside area. Triple towing is not allowed. Maximum occupancy is eight per site, with four people included in the base fee and $8/day per additional guest. If you plan to ride out a Susquehanna Valley winter on-site, plan for skirting and heat management at this elevation.
What's On-Site
In peak season the water park is the headliner: water slides, splash pads, a kids’ pool, and a full-size swimming pool. The activity list runs deep beyond the water, including glow-in-the-dark mini golf, bumper boats and paddle boats, a jumping pillow, pedal carts, golf cart rentals, and an arcade. The entertainment pavilion runs a full summer calendar of crafts, foam parties, pool volleyball, bingo, and outdoor movie nights. Year-round, the camp store stocks essentials, snacks, and propane, and restrooms, showers, and laundry are on-property. Fishing access along the Susquehanna is direct from the campground, and WiFi covers the property. Note that the water park and most of the summer activity calendar are seasonal, so an off-season stay is quieter and more practical than recreational.
What Guests Say
4.1 stars across 1,215 Google reviews. Repeat visits are the strongest theme: families come back year after year, often booking the next trip before they leave. In peak season the water park, pool, and the sheer volume of kid-friendly activities pull the most praise. Cleanliness in the cabins and the helpfulness of the campground team show up consistently. Long-term and extended-stay RVers highlight the riverfront sites and the relaxed atmosphere, which is the side of the property that matters most for an off-season or year-round stay.
Other Camping Options Near Northumberland, PA
Year-round and off-season availability is limited in central Pennsylvania, and most options are seasonal. Always call ahead to confirm winter hours and hookup availability before you plan around them.
Shikellamy State Park
Shikellamy State Park spans a 50-acre marina section on the Susquehanna and a 190-acre overlook section with scenic views and hiking trails. The park is open year-round from sunrise to sunset, but it has no RV campground or hookups, so it works as a recreation stop near a year-round site rather than a place to park the rig overnight.

Things to Do from Your RV Base Near Northumberland
The Susquehanna River is the area’s defining feature, and Splash Magic has direct fishing access from the campground. Across the river, Shikellamy State Park’s marina section offers boat launches and shoreline access. Even in the off-season, the riverfront and overlook trails are open for fishing, walking, and wildlife watching.
Shikellamy State Park’s overlook section delivers some of the best Susquehanna Valley views in the region, with hiking trails open year-round from sunrise to sunset. Downtown Sunbury and Northumberland keep restaurants, groceries, and services within a short drive, which matters for a winter stay when you are not leaving for amusement parks.
Knoebels Amusement Resort in nearby Elysburg is the area’s marquee summer attraction, running roughly late April through October, so it is a seasonal day trip rather than a year-round one. Bloomsburg and the Bloomsburg Fair grounds are a short drive east. For winter stays, the practical day trips are the state-park trails, the river, and the towns of Sunbury, Northumberland, and Lewisburg.
Seasonal Guide for Year-Round RVers Near Northumberland
Summer (June through August)
Peak season. The water park and full activity calendar are open, and the campground fills with families. Warm, humid days are typical for the Susquehanna Valley. This is the busy, recreational face of the property.
Fall (September through November)
Crowds thin and the winter monthly program begins in September at $600/month. Crisp days and fall color along the river make this one of the better windows for a quieter stay. Confirm which amenities remain open as the season winds down.
Winter (December through February)
Cold and short-dayed, with occasional snow. The winter monthly site is the relevant option here. Plan for skirting and tank-heat management, and confirm office, laundry, and camp store hours before you arrive.
Spring (March through May)
The winter monthly rate runs through April. Weather warms through May as the campground prepares to reopen its summer amenities. A good shoulder window for an affordable extended stay before peak pricing returns.
