So glad we stumbled across this activity when researching our Canada Trip. Felt so surreal to be floating along, up to our necks in steaming Epsom Salt solution, our heads almost level with the chilly waters of the bay! Had the company of a seal for part of our journey too :) We may have missed info on their website, but we weren't sure if we needed to take our own towels - we did! Changing facilities are a bit basic, but just about adequate. We did a late afternoon trip, hoping to catch a sunset - unfortunately it was too cloudy, but we did enjoy seeing the city lights coming on during the return leg of our cruise. Wished we'd paid more attention to exactly where we'd immerged from the dock onto the main waterway, as finding our way back in among all the other (much bigger) boats moored up was a bit of a challenge!
