Richardson Bay Is the Runway on This Golden Gate Flight
A six-seat floatplane takes off from the water in Marin, heads for the Golden Gate, passes Alcatraz and lands back on the bay.
This flight leaves from the water. Seaplane Adventures flies out of its seabase in Mill Valley, takes off from the waters of Marin and, by its own description, lands back on Sausalito's Richardson Bay at the end. Every passenger gets a window seat.
📍 The booking has one option, the Golden Gate Tour, priced per person. The listing requires two adults per booking, and a solo booker pays for the second seat directly to the operator at check-in. Everyone booked has to be 13 or older: the form has no seats for ages 3 to 12, and infants ride on an adult's lap. Food, drinks and gratuities are not included.

The listing runs the route in this order: over Stinson Beach and the redwoods of Muir Woods National Monument, along the Marin Headlands, a bird's-eye view of the Golden Gate Bridge, then the Financial District, Pier 39, Fisherman's Wharf, Alcatraz and Angel Island. All of it is seen from the air, with no stops.
The listing says the route may vary with the weather, and the operator adds federal airspace rules as a second reason. On foggy days the operator says it tries to get over the bridge anyway or shifts the route to find a view of the bridge.
The pilot points out the landmarks on the way. Several travelers between 2024 and 2026 singled out that commentary, describing pilots who were funny and full of local history.
A Beaver on Floats, and a 260-Pound Seat Limit
The aircraft the operator lists for its seaplane tours is a de Havilland Canada DHC-2 Beaver, which it describes as made for water, with seats for six.
The operator weighs every passenger at check-in, caps a single seat at 260 pounds and carries no seat belt extenders; anyone over the limit has to buy a second seat. It says it will not refund a single seat bought for someone over the limit and offers another time or date instead. The booking form asks for each traveler's weight up front.
The listing does not recommend the flight for travelers with spinal injuries. For infants, the operator has only a few ear protection headsets and suggests parents bring their own noise-canceling headsets or earplugs.
Small Bookings Can Move to Another Slot, or Another Aircraft
By the operator's own terms, a seaplane goes up with at least three passengers, while this listing sells bookings of two. The operator says bookings below its minimum are paired with other passengers and can be moved to another time or date to fill the plane.
Travelers have described a second kind of swap. In 2025 one wrote that the seaplane did not fill and the group flew in a helicopter instead; in 2026 another was offered a helicopter when the seaplane needed maintenance. Both enjoyed the switch. Leave some slack around the booked time and keep fixed plans well clear of it.
Getting to Mill Valley, and the 30-Minute Check-In
The flight starts and ends at the operator's seabase at 242 Redwood Highway Frontage Road in Mill Valley, which it puts about 10 minutes from the Golden Gate Bridge. Parking there is free. This booking has no shuttle option. The operator's terms say a shuttle from Fisherman's Wharf has to be arranged with its reservation desk before the flight date, and two travelers in 2025 ended up without one on the day.
The listing asks you to arrive 15 minutes early, but the operator's own rule is 30 minutes, and it says flights leave on time without late parties and without refunds. Everyone signs a waiver before boarding, sent with the confirmation email or done at the base.
On October 11, 2026 the booking calendar showed departures at 10:30 AM, 11:30 AM, 12:15 PM and 2:20 PM on Mondays and Thursdays through Sundays.
Cancel at least 24 hours out for a full refund on this booking; the operator's direct bookings run on 72 hours. The pilot makes the weather call up to 30 minutes before takeoff. Then come 25 to 30 minutes in the air, by the operator's estimate, and a landing back on the bay.
