Kelp forests are incredible marine ecosystems. Kelp looks like a chaotic disaster on the surface, but under the water resolves into tall, tree-like forms that are full of wildlife. It's well worth making a trip to Monterey, CA (about a 3 hour drive from San Francisco) to see the beautiful kelp forest exhibit at the aquarium there. If you're a scuba diver, Monterey is also the best place to see this world firsthand. Unfortunately, it can take a few dozen dives before you have a day with clear enough visibility for a real underwater panorama, but once you see it, you'll be hooked. Be sure to dive with someone experienced, rent proper cold-water gear, and get the briefing on how not to get stuck in kelp on the surface. It's not dangerous, but it can take all the fun out of diving.
