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

Loved the overall campground and nature watching. Would not stay in site 60 again in summer due to lack of shade, which makes you retreat inside your camper for afternoon and early evening.

Very fun to be so close to the water! Noise travels in this campground, few trees on the waterfront sites.

The campground is amazing and so much wildlife around. Campers were friendly and respectful. For site 44, there is street lamp that is obnoxious. It probably impacts sites around 44 as well. When I was there it would blink on and off. When on it is too bright.
