Travel Tips
Planning Your Visit
A journey to the Thousand Islands requires a little foresight to make the most of its unique offerings. Given its popularity, especially during the peak summer months of June to August, booking accommodations, boat tours, and any specific activities well in advance – ideally 2-3 months out – is highly recommended. A car is essential for navigating between the charming towns like Alexandria Bay and Clayton and reaching various points of interest; while towns are walkable, the distances between them are not.
Remember to pack smart for this riverside adventure: layers are key, as evenings on the water can be cool even in summer, and strong sun protection (sunscreen, hat, sunglasses) is a must due to the water’s reflection. If you plan to visit the Canadian side, ensure every member of your party carries a valid passport. Budgeting around $150-$300+ per night for lodging and $30-$70 per person for boat tours, plus castle admissions (approx. $15-$17 per castle), will give you a good starting point for your adventure.
