                                                              Plan carefully your trip to minimize your environmental impact, please avoid sunscreen / mosquito repellent or other skin products for all water activities. Whenever possible, choose rechargeable batteries and avoid to carrying things like disposable razors, plastic bags, plastic water bottles, etc. We are in a very fragile and pristine environment and is our responsibility to keep it that way. 

                                                              CCR diving is a highly demanding activity with a specific mindset and requires very good trim, buoyancy, propulsion, and awareness. We will do our best to improve your skills and knowledge, also we will set the best training plan according to the skills and experience of each diver to help them to succeed in the course but consider sometimes we need extra days to achieve the goals with a classroom or water sessions and we apply extra rate if is necessary. We strongly recommend to the students plan at least two extra days just in case. 

                                                              NOTE: Please bring change of clothes & towels for cenote training days.
