About

The Seymour Marine Discovery Center is the public face of UC Santa Cruz's Long Marine Laboratory, one of the premier marine research institutions on the Pacific Coast. For families, it offers something genuinely rare: a museum staffed by active scientists and graduate researchers who are studying the very animals and ecosystems on display.

The centerpiece of the indoor exhibits is the marine touch tanks, where bat rays, sharks, sea stars, and crustaceans live in naturalistic habitats designed for tactile interaction. Unlike many aquariums where touch tanks feel like afterthoughts, the Seymour Center has made them a primary attraction, staffing them with knowledgeable docents who guide children through proper handling techniques and explain the biology of each animal.

The main exhibit hall covers the ecology of the Monterey Bay National Marine Sanctuary with particular depth on marine mammals, deep-sea biology, and the human impacts on ocean health. The exhibits are designed for genuine comprehension rather than superficial impressiveness — information is layered so that a 5-year-old and a 12-year-old can both walk away having learned something at their level.

Outside, the 87-foot blue whale skeleton — nicknamed 'Blue' — dominates the courtyard. This skeleton came from a whale that beached in 1979 and took researchers years to assemble. The scale is staggering even for adults.

Behind the main building, the outdoor marine mammal enclosures sometimes house rescued animals being rehabilitated, and a paved bluff trail overlooks the ocean with direct views into the kelp beds below.

For families who want a science museum experience without the sensory overload and crowds of a major metropolitan aquarium, the Seymour Center is a quiet, intellectually rich alternative. The combination of real research, expert staff, and spectacular natural setting makes it one of the most underrated family attractions in the entire Monterey Bay region.

Why Kids Love It

The Seymour Center is UCSC's public marine laboratory — an actual working research facility where scientists study whales, sea otters, and ocean health. Kids who visit are not just looking at exhibits behind glass; they are walking through a building where real research is happening every day. Docents are frequently UCSC graduate students who can answer questions that would stump most textbooks, and they genuinely love talking to curious kids.

The touch tank is the undisputed highlight for younger visitors. Bat rays glide slowly just under the water surface and actively approach hands held still at the edge — the feeling of a ray's smooth, rubbery wing brushing your palm is unlike anything in a landlocked city. Hermit crabs, sea stars, and urchins fill adjacent tanks where kids can handle specimens under docent supervision.

The tactile experience creates a connection to marine life that photographs and videos simply cannot replicate.

Outside the main building, a full blue whale skeleton hangs overhead — at 87 feet, it is one of the largest mounted whale skeletons in the world. Standing next to the skull, which is the size of a small car, gives kids an immediate and visceral understanding of ocean scale that no exhibit panel could convey. The outdoor walkway leads to a bluff overlooking the ocean where sea otters and harbor seals are frequently visible in the kelp beds directly below.

Pro Tips from Parents

  • Ask docents about the current research projects happening in the lab behind the center — they often share fascinating behind-the-scenes details.
  • The blue whale skeleton outside is free to view even without buying admission — great for a quick stop.
  • Combine with Natural Bridges State Beach next door for a full half-day coastal nature experience.
  • Check the website for free First Tuesday admission and special science programming dates.
  • The marine-themed gift shop has genuinely educational toys and books, not just generic trinkets.

What to Bring

  • Light jacket (the building is air-conditioned and the outdoor section can be windy)
  • Curiosity and questions — docents love engaged kids
  • Camera for the whale skeleton
  • Snacks (no food on site)

Tips to Save

  • Visit on the first Tuesday of the month for free admission.
  • The museum is small enough to fully explore in under 2 hours, so it pairs well with a trip to adjacent Natural Bridges State Beach (5-minute walk).
  • Admission is genuinely affordable compared to larger aquariums in the Bay Area.
