Lake Atitlan is one of the safest places in Guatemala for tourists. But it is still important to take precautions. The biggest danger for most tourists is robbery. We have been going there for nearly 15 years and haven’t had any issues, personally. However, we always take the following precautions, just to be safe: Never walk alone at night – we always take tuk tuks if we are out after dark. Hike in groups. Never carry obvious valuables. Some people carry a "throw away wallet" when hiking with a small amount of money in it. Lock away or hide valuables in your accommodation; we don't have to do this where we stay at Pasajcap Rentals as it is very secure but we have heard of break-ins in other places. Be aware that Guatemala has strong drug laws and have made examples of tourists in the past. When swimming, watch for boats and don’t dive into the lake without checking for rocks first.
