What we do

Our Services

Daily Tours

Monterey Bay Eco Tours offers daily tours on the El Cat year round. The hour and a half trip takes you from El Cat’s berth at Moss Landing Boatworks through the winding tidal flats of Elkhorn Slough deep into the reserve.

Private Charters

We can accommodate private groups as large as 32 and will schedule a private charter tailored to fit your needs. Our boat is a great platform to move around and mingle with your business partners or extended family in a tranquil outdoor setting. Catering is also available. Contact us for our special group rates.

School Groups

As the boat can seat 32 passengers and is a safe platform for kids of all ages we are a great option for school groups. Interested in field trips to study ecology, natural history, wildlife, birdwatching, stewarding our environment and so much more? We are excited to accommodate school groups and have special groups rates for education.

Birding Tours

The Elkhorn Slough is visited by over 340 species of birds throughout the year. This tranquil estuary has such an abundant variety of habitat for so many unique species that it is a birder’s paradise! Photographers love our boat because of the lack of vibration from the electric motors. Contact us for the special birder group rate. Click here for link to Audubon Elkhorn Slough site.

What Drives Us

Our Mission

Our goal is to provide a delightful educational experience on a comfortable, eco-friendly and quiet electric catamaran. We believe that viewing the natural beauty of the Elkhorn Slough should have minimal impact on the wildlife and environment. It is our vision to become a leading example of a charter boat company that demonstrates a model of environmental sustainability.

John, Daly City, CA

My family of 4 booked a tour with Monterey Bay Eco Tours after checking out other tour companies. We totally enjoyed the day. Our guide made sure we were comfortable, and was very accommodating with our children. We had a fabulous day and would recommend Monterey Bay Eco Tours to anyone considering an Elkhorn Slough Tour.

Anita, Phoenix, AZ

This was our fourth trip with Monterey Bay Eco Tours and it lived up to our very high expectations. The ship was quiet, clean, comfortable, and excellently crewed. A shout-out to our wonderfully informed guide who pointed out local flora and fauna. Excellent!
