I may be in Switzerland in Oct and have 2-3 days to take a short trip to dive. Is there any place you would recommend to dive that is a short flight away (approx. 2 hours or less) that you would recommend that would be warm (above 70F), clear and has good diving. I have seen online some locations in Europe to dive but at that time of year it looks like it would be well below 70F. Thanks. TK
