Crawl through the B-39 Soviet sub for a legit claustrophobia test—it is easily the wildest thing on the Embarcadero. The Star of India is cool for the aesthetics, but skip the dated indoor museum exhibits that feel stuck in 1995. You only need two hours here before the novelty wears thin. If old hulls aren't your speed, save the entry cash for a San Diego Harbor Speed Boat Adventure instead. Wear comfortable shoes.
Sitting directly along North Harbor Drive, this collection of floating hardware serves as a tangible record of naval engineering and maritime labor. Rather than viewing static displays behind glass, you walk across creaking decks and descend into cramped pressurized steel hulls that define the era of Cold War technology. The draw here is the physical scale of the vessels, particularly the B-39 submarine, which forces you to navigate tight hatches and narrow passageways. It is a utilitarian experience, prioritizing the cold reality of life at sea over polished interpretive panels or glossy digital installations.
Navigating the interior of the B-39 submarine or the lower decks of the tall ships involves very tight hatches and steep ladders, which can be challenging for those uncomfortable in confined, narrow spaces.
Two hours is generally sufficient to walk through the major floating vessels. Most visitors find the novelty fades quickly after exploring the exterior decks and the main engine rooms of the primary ships.
The stationary indoor displays often feel outdated and static compared to the ships themselves. You should focus your limited energy on boarding the actual vessels moored along the pier instead of reading placards.
Parking along North Harbor Drive is limited and expensive during peak hours. Arriving via public transit or walking from the downtown district provides a much more efficient arrival experience without the stress of meters.
Combining your trip with a San Diego Harbor Speed Boat Adventure allows you to view these historic hulls from the water, providing a necessary perspective on the scale of the ships against the skyline.
