We love camping at Thomson Causeway until this time. We did not know that the Mayflies were out. We had a campsite on the water and were attacked by the bugs. I would definitely check in the month of June/July for bug conditions. Otherwise it is one of our favorite places to camp.

We loved our site - very spacious! Was nice to see the Park Rangers walk through a few times. We were across from a nice grassy area (site 21), and my only complaint is that apparently people don't feel the need to pick up their dog poo there. ARG. I know there are bags and disposal stations in other parts of the campground - this may be a perfect place to put one in hopes it may encourage people to use it. Love it here!

This is a good spot. Loved it. Better than the last spot. The water hookups are good. Cant wait for all spots to be concrete patio.

Would have been 5 stars but the "buddy sites" in the new area were not clearly defined when I originally booked site 89.

View was spectacular. The proximity for facilities was disappointing, but the cleanliness was even worse. The number of showers per campsite was very low too. Inconsistent enforcing of powered vehicles by different personnel. Limited play area for kids. Campers walked through your campsite without a care. Very different experience than our family is used to. If we come back it would be for the view, not any type of amenity offered.

We always enjoy camping at Thomson Causeway it’s quiet friendly people and staff and volunteers and it’s away from home but close enough if we need to get anything we need

Lovely, very well kept campground. Sites are very level, and all of the sites in my loop had a water view.
