It's a great idea to bring plenty of water each day, as there might not be a place to fill up. Be sure to check your route notes before setting off for the day, as there might be a filling station, especially on major trails. Of course, always be careful when drinking tap water or water from streams. Your Country Guide found in the Trip Info section of your account will also have information on local water.
An easy way to eliminate any worries is to get a filter bottle. We've partnered with Water2Go, which are reusable water bottles that have a built-in filter. It kills 99.9999% of contaminants like bacteria, viruses, and chemicals, allowing you to refill from any free-flowing, non-saltwater source like streams! Use code MA30 to receive 30% off.
