Belle Isle Aquarium is a free public aquarium on Belle Isle State Park in the Detroit River, operated by the Belle Isle Conservancy. It is recognised as the oldest continuously operating aquarium in North America, having first opened on 18 August 1904. This guide covers opening hours, access, parking, the Michigan Recreation Passport requirement, what to see, accessibility, and practical tips for planning your visit.
Last updated: June 2026. This guide is based on the official Belle Isle Conservancy plan-your-visit page. The aquarium is currently open during a $10 million renovation project covering HVAC, site drainage, and accessibility improvements — normal visiting is unaffected, but construction activity is visible on site. Many third-party guides also state incorrect opening days: the aquarium is open Thursday through Sunday only, not Wednesday–Sunday or Friday–Sunday as some sources claim.

Belle Isle Aquarium ticket prices
Admission to Belle Isle Aquarium is free. A $5 donation is encouraged to support operations; the aquarium is run entirely by the Belle Isle Conservancy, a nonprofit, with no government funding for day-to-day operations.
Driving onto Belle Isle requires a Michigan Recreation Passport. This is a vehicle permit — not an entry fee for the aquarium itself. It is required by law for all vehicles entering any Michigan state park, including Belle Isle. Pedestrians, cyclists, and bus passengers do not need a Recreation Passport. Passports can be purchased through the Michigan DNR website or at the point of vehicle registration.
The aquarium is not included in any city pass scheme. Opening hours and ticket prices were checked on the official Belle Isle Conservancy website and last updated in June 2026.
How to get to Belle Isle Aquarium
By public transit: The DDOT #12 Conant bus stops directly in front of the Belle Isle Aquarium and Anna Scripps Whitcomb Conservatory on the island. Buses operate Monday–Saturday 7:30am–8:00pm and Sunday 8:00am–6:45pm. Check the DDOT schedule for current timetables.
By car: Access is via the MacArthur Bridge from Jefferson Avenue and East Grand Boulevard. A Michigan Recreation Passport is required for the vehicle. During peak weekends, the bridge may be temporarily closed by the MDNR when the park reaches vehicular capacity. Text GEM to 80888 for live park updates.
By bike or on foot: The MacArthur Bridge and the Detroit Riverwalk Trail both connect to the island without requiring a Recreation Passport. MoGo bike-share stations are available at the aquarium and the beach.
By rideshare: Lyft and Uber drop-off zones are located near the aquarium. Note that rideshare vehicles also require a Recreation Passport to drive onto the island — confirm with your driver before booking.
Parking at Belle Isle Aquarium
Parking is available throughout Belle Isle State Park near major landmarks, including spaces near the aquarium. A Michigan Recreation Passport is required for vehicle entry — this is separate from any parking charge. The lot adjacent to the aquarium can fill quickly on warm weekend afternoons. Arriving before noon significantly reduces the risk of long queues at the MacArthur Bridge.
How long to spend at Belle Isle Aquarium
Allow 45 to 90 minutes for the aquarium itself. The building covers around 10,000 square feet and is compact compared to modern aquariums, but the historic architecture and individual exhibits reward careful exploration.
Most visitors combine the aquarium with the adjacent Anna Scripps Whitcomb Conservatory (open Wednesday–Sunday 10am–5pm, free entry), making a half-day visit easy to plan. A full day on Belle Isle is possible by adding the 5.4-mile island loop trail, the Dossin Great Lakes Museum, and the Oudolf Garden.
Accessibility at Belle Isle Aquarium
The aquarium is accessible to wheelchair users, and wheelchair-accessible routes connect the aquarium to other major sites on the island. The ongoing $10 million renovation project includes accessibility improvements to the building and site drainage.
For specific accessibility questions, contact the Belle Isle Conservancy at 313.331.7760 or [email protected]. The DDOT #12 Conant bus stops directly in front of the aquarium, making transit access straightforward.
Pets are welcome on Belle Isle on a six-foot leash, but dogs are generally not permitted inside the aquarium building.
What to see at Belle Isle Aquarium
The building itself
The aquarium was designed by Albert Kahn and opened in 1904 alongside the sister building next door, the Anna Scripps Whitcomb Conservatory. The interior is defined by a vaulted ceiling covered entirely in green glass tiles, creating an immersive subaquatic atmosphere that has remained largely unchanged for over 120 years. In 2023, a national survey by the Aquarium Store Depot ranked it the most beautiful aquarium in the United States.
The building closed in 2005 due to budget cuts by the City of Detroit and was rescued and reopened on its 108th birthday — 18 August 2012 — by the Belle Isle Conservancy, which has operated it entirely with volunteer and donor support ever since.
Freshwater fish collection
The aquarium’s primary focus is freshwater species from the world’s great lakes and rivers, reflecting its Great Lakes setting. Highlights include species native to the Detroit River and the broader Great Lakes ecosystem, alongside freshwater species from rivers around the world. Notable residents have included African Lungfish, Mbu Pufferfish, Electric Eels, and long-snouted Gar fish — species that have been in the collection for decades.
Marine and saltwater exhibits
In addition to the freshwater collection, the aquarium maintains exhibits of colourful marine fish and corals, providing a contrast to the Great Lakes focus. The combination of freshwater and saltwater displays within the compact single-gallery space means the variety of species is considerably greater than the building’s modest footprint suggests.
Conservation work
The aquarium is actively involved in conservation beyond display. Staff work with the Michigan Department of Natural Resources on programmes to help repopulate lake sturgeon in the Detroit River, and conduct frog and mudpuppy studies on Belle Isle to monitor ecosystem health.
Science Saturdays
Monthly Science Saturday presentations, typically held on the second Saturday of each month, offer hands-on learning sessions for visitors of all ages. Check the Belle Isle Conservancy events calendar for current dates and topics.
