Don't know about Guam but I got my certification on the island of Saipan just to the north and there is one there called the Blue Grotto that is absolutely GORGEOUS, especially in mid-afternoon when the sunlight is refracted through the three tunnels leading out into the open ocean. It was my first open water dive, actually, for all that it is considered to be an advanced dive.<a class="user" href="http://www.zianet.com/lanelli/art38.htm">http://www.zianet.com/lanelli/art38.htm</a><a class="user" href="http://www.cnmi-guide.com/svt/grotto.jpg">http://www.cnmi-guide.com/svt/grotto.jpg</a><a class="user" href="http://grantnsaipan.blogspot.com/2007/01/grotto.html">http://grantnsaipan.blogspot.com/2007/01/grotto.ht ...</a>
