Adventure Tours Abroad
Adventure tours that include scuba diving appeal to those that are drawn to water and the realms of the oceans.
The world beneath the sea beckons, inviting you to explore its’ depths and witness firsthand the colorful world of the reef. Schools of shimmering silver iridescence flash by in unison as though choreographed by an unseen dance master. Fan tailed corals wave lazily in the current. Only the spiraling bubbles rising upwards give evidence of the divers swimming in tandem. You feel your body relax and your worries forgotten as you are mesmerized by the scene in front of you. Inquisitive fish swim by and you are in awe of the myriad of varieties. You smile widely, momentarily caught up in the beauty, causing your mask to flood. You reflexively clear it, confident in your skills.
While diving along the bottom of the ocean floor is common, thrill seekers may be drawn to different types of adventure tours. Not for the claustrophobic or the timid, the exploration of underground water filled caverns is a departure from regular diving – adventure tours that are beyond description. Many countries have an extensive system of these caverns. In Mexico, they are known as “ceynotes”. The crystal clear water affords visibility for a hundred feet or more. While these caverns can be explored by kayak, snorkeling or scuba diving, scuba diving affords a closer examination.
While cavern diving, divers may encounter “haloclines”, an interesting phenomenon that occurs where fresh water and sea water meet. Haloclines are common in water-filled caves near the ocean. Less dense fresh water from the land forms a layer over salt water from the ocean. Underwater cave explorers passing through the halocline stir up the layers. The divers will notice that the water appears hazy; the haziness caused by differences in refraction. Swimming slightly to the right or left will immediately clear the distortion that the diver sees. A halocline will likely occur simultaneously with a pycnocline – a cline based on difference in water density. Divers may also feel a difference in temperature, known as a thermocline. This is caused by increased salinity of the water. A chemocline is based on difference in the chemistry of water. Whew! Now you know more about “clines” than you ever imagined!
Cavern diving is not “true” cave diving as divers are typically within a minute of an air pocket, allowing them to surface as necessary. “True” cave diving is an advanced certification where divers must rely entirely on compressed air to breathe for the duration of the dive and without access to the surface or to an air pocket. This dive specialty is an advanced skill; adventure tours that are restricted to the experienced diver.

Hey, just looking around some blogs, seems a pretty nice platform you are using. I’m currently using WordPress for a few of my sites but looking to change one of them over to a platform similar to yours as a trial run. Anything in particular you would recommend about it?
