Three Island Crossing State Park Campground

The above rate reflects the senior discount which is available to all seniors age 62 and older Monday thru Thursday. I actually paid a total fee of $21.50.
I only spent one night and didn't really have an opportunity to look over the entire campground or park. I stayed in the upper loop (Site #3). Very nice, gravel, level and large sites up here. Plenty of space at each site (which include water and electric hookups, a picnic table and fire ring) as well as nice spacing between sites. Other reviewers state the sites in the lower loop are much more closer together. The bath house has separate rooms for toilets and showers. The showers are nice with good hot water and pressure, though it would be nice if each stall had a shower curtain in addition to the privacy door. That would have kept things much warmer on a chilly, late September morning. There is a dump station with both rinse and potable water between the camping loop and exit from the park. A reservation is not required at this campground, but the park is a busy one. I took a chance after monitoring the reservation website closely for a couple of days and was able to snag my site as a drive up on a Thursday afternoon around 1PM. It saved me the $10(!!) reservation fee.
Relatively easy to get to the park from I-84 and the interior roads and camp sites easily handle any sized rig.

In the 1800's, Gus Glenn built a ferry to cross the Snake River at this location. Being on the Oregon Trail, the ferry eliminated pioneers' risk fording the fast-moving river. This is a very nice state park, well-maintained with big shade trees. The single campsites are smallish. The 'companion' sites for two rigs are bigger, but more money. Be sure to ask for the seniors discount, 1/2 off.

We arrived an hour before check-in, so we had to wait in the day use area. I understand that for park maintenance reasons they need that hour between check out and check-in times to service the sites. We spent the wait in their visitor center which was loaded with fascinating displays about the Oregon Trail.

Our site (#3) was pretty level. Our auto-leveling system only made minor adjustments. The 50amp breaker was broken, but when I brought it to the attention of park staff, they addressed it IMMEDIATELY. Speaking of staff, they're very friendly and visitor focused.

Their are two loops in the park. The upper loop sites are more spacious and spread apart than those in the lower campground. The lower campground is the perfect campground for families and groups camping together. It has a huge covered area for group gatherings.

When selecting sites, be sure to look at the map. Cabins in the park are very close to some campsites.

The restrooms and (free) showers were immaculate. Each site has power and water but no sewer. There are well placed and well maintained dump stations in the park.

The Y-Knot Winery is next door with a path from the park directy on to their property. The winery has their own RV park and is a Harvest Host. We didn't dine there, but other reviews indicate that the food is good. They also have a golf course which looked quite nice.

Stopped here on my way home from southern Nevada to Washington. It’s an easy off the freeway through the small town of Glenns Ferry. The upper campground sits on a plateau overlooking the Snake River. The lower parking lot is closer to the river. “Senior” rate for a site with water and electric is $20 for a NV resident and $21.50 for non-resident mid-week. There are clean restrooms and it was super quiet while I was there although super windy on the tail of a storm. There’s was a train whistle way off in the distance. Nice. Lots of grassy areas and trails for walking the dog and a new interpretive center. There is a winery next door and it has its own RV Park. I’m told the winery has excellent food. I only had to do minor leveling and the other sites looking good as well. Dirt or gravel pads. Pretty darn nice place to stay or overnight.

We stayed here a single night when we were traveling further east in July 2022. We booked a site online in advance but there were many sites available upon our arrival.

Unfortunately our site was right next to a ditch and a walking path that went across it to a group tent area near the dock. None of that was obvious from the map online. Unfortunately, group tent campers were walking right next to our trailer, within the boundaries of our skinny site, to get to and from their group area all evening.

However, we still enjoyed the grounds. We had a partial hookup and it wasn’t too far to walk to the old wagon they have set up there in the day use recreational area.

I’m so glad we had a site with trees (there were many with none) because it was very hot.

There’s a lot of sites at this park, they’re all clean and the area is pretty. It was $36 for a full hook up. We got here on Thursday night in January and there were only two other rigs a good distance away, by the time we left on Saturday there were only about 5 others. Nice quiet place and if you’re looking for somewhere with paved roads in the winter, this is a great spot.
