Snorkeling in pool around Lausanne?
Next month my girlfriend and me are planning a vacation and we plan to include some snorkeling excursions. Since I did it long time ago and she never did, we wanted to practice a little bit beforehand not to lose any precious (paid) time on site.
Can anybody give any advice on whether it is possible to practice somewhere? Preferably around Lausanne area and in the pool. I know that there are some scuba diving courses in Geneva, but have not found anything regarding the possibility of snorkeling in the pool.
