When visiting Lake Te Anau, it’s important to be prepared for the area's variable weather. Bring layers of clothing, as temperatures can fluctuate throughout the day, especially during the cooler months. If you plan on engaging in water activities like kayaking or fishing, make sure to check water conditions and safety guidelines. While there are several facilities around Te Anau town, the lake itself is a relatively undeveloped wilderness, so be ready for a more natural, less commercialized experience. Make sure to carry sufficient food and water, especially if you’re planning a longer outing.

Lake Te Anau is located directly next to the town of Te Anau, making it easy to access by foot, bike, or car. If you're staying in Te Anau, the lakefront is just a short walk from most accommodations, and several tracks along the lake offer scenic walking and cycling routes. If you prefer a more guided experience, boat tours of the lake are available, offering access to remote parts of the lake and nearby islands. For those arriving from outside Te Anau, the town is about a 2-hour drive from Milford Sound and can be reached via State Highway 94.

Lake Te Anau can be visited year-round, with each season offering a different experience. Summer (December to February) is the most popular time, with warm temperatures and long days perfect for outdoor activities like cruising and hiking. The autumn months (March to May) offer a quieter atmosphere and beautiful changing foliage around the lake. Spring (September to November) brings lush greenery and the arrival of migratory birds. Winter (June to August) is colder but offers the chance to see snow-covered landscapes, perfect for a peaceful retreat or a winter adventure.

While Lake Te Anau is often part of longer explorations of Fiordland National Park, it also makes for an excellent day trip destination.

Another popular option is to walk or cycle along the Te Anau Lakefront Trail, which offers panoramic views of the lake and nearby hills.
