Earlier, I asked about the size of the "up to 18 ft" sites at Killarney. Now that I have been there, I'll report on the sites. The campground wasn't very full the June 3 weekend, so I didn't need to worry. However, of the "medium" size (up to 18 ft) sites, there were some my 20ft trailer would fit into, some it would not, and some that it would fit into but the maneuvering to get into it would be a challenge.
Many of the sites are down dead ends, not loops, with not much turn around, so cruising through camp looking for a site would not have been fun.
The recommended "old school bus" fish shop is closed for remodeling. They are moving into a real building, and a rather large one. They hope to be in by July, but they have a long way to go. I think that Killarney is slowly getting yuppified.
