Boldt Castle Stopover
- Boldt Castle is only accessible by water and is an official port of entry into the United States.
- It’s a must-visit for architecture lovers and romantics alike, as the castle was built by George C. Boldt as a grand gesture of love for his wife.
- You’ll cruise past iconic island homes and lighthouses before stopping for what’s advertised as a 1–2 hour visit to explore the castle grounds.
💡 Honest Review: While the experience is undeniably beautiful and picturesque — with panoramic views of the islands and the castle emerging like a fairytale — border entry processing can eat into your stopover time. You may only have about an hour to explore the castle after going through U.S. customs. So plan your expectations accordingly.
