If you’ve ever stood on the shore at Dillon Beach and looked east across the mouth of Tomales Bay, you’ve probably felt the pull. That long, calm body of water stretching south between the Point Reyes peninsula and the Marin mainland is one of the most beautiful paddling destinations in Northern California — and it’s right in your backyard when you’re staying in Dillon Beach.
Tomales Bay is a narrow, thirteen-mile-long estuary formed by the San Andreas Fault. The geology alone is remarkable — you’re literally paddling along a tectonic plate boundary. But most people come for the wildlife, the stillness, and the feeling of being somewhere genuinely wild just an hour north of San Francisco.
Here’s everything we’ve learned from years of paddling these waters.
Where to Launch
There are two main options for getting on the water near Dillon Beach, and they offer very different experiences.
Lawson’s Landing
Lawson’s Landing sits right at the northern tip of Tomales Bay, just a short drive from Dillon Beach proper. It’s a privately operated campground and recreation area at the end of a long gravel road. There’s a boat launch and easy beach access where you can put in a kayak.
Launching from Lawson’s gives you access to both the bay and — if you’re experienced — the open ocean through the bay’s mouth. Most paddlers stick to the bay side, heading south along the eastern shore. The water near the mouth can be tricky with currents and swells, so unless you know what you’re doing, keep to the calmer interior.
There’s a day-use fee to access Lawson’s. You’ll need to bring your own kayak or arrange a rental elsewhere — they don’t rent kayaks on-site. Parking is easy, and the staff can point you toward the best launch spots depending on conditions that day.
Blue Waters Kayaking in Marshall
About 20 minutes south of Dillon Beach on Highway 1, the small town of Marshall sits on the eastern shore of Tomales Bay. Blue Waters Kayaking operates out of Marshall and is the go-to outfitter for the bay. They rent single and tandem kayaks, stand-up paddleboards, and run guided tours ranging from a couple of hours to full-day excursions.
If you’re new to kayaking or just don’t want to haul your own gear, this is the move. Their guides know the bay intimately — where the seals haul out, where the bat rays congregate, which coves are sheltered when the wind picks up. They provide all the equipment including PFDs, paddles, and dry bags.
Launching from Marshall puts you in the heart of the bay, which means calmer water right from the start. You can paddle north toward the mouth or south toward the quieter, more protected upper bay. Either direction is beautiful.
Bay Side vs. Open Ocean
This is the most important decision you’ll make, and for most people the answer is simple: stay on the bay.
Tomales Bay is sheltered, relatively shallow, and usually calm — especially in the morning. The water is flat enough for beginners, and even on windier days the bay rarely produces waves that would trouble a competent paddler. It’s the kind of water where you can relax, drift, and actually look around instead of constantly bracing.
The open ocean outside the bay mouth is a completely different story. The Pacific here is cold, powerful, and unpredictable. Strong currents run through the narrow mouth of the bay, particularly during tidal changes. Swells roll in from the northwest and can build quickly. Fog reduces visibility to almost nothing. This is intermediate-to-advanced water, and even experienced ocean kayakers treat it with serious respect.
If you’re visiting Dillon Beach for a vacation and want a memorable paddle, the bay gives you everything — stunning scenery, abundant wildlife, and that deep sense of quiet that makes you forget how close you are to civilization. Save the open water for another trip with proper gear and experience.
What You’ll See on the Water
Tomales Bay is a state estuary and one of the most ecologically rich waterways on the California coast. Paddling here feels like being inside a nature documentary.
Harbor seals
You will see harbor seals. It’s almost guaranteed. They haul out on sandbars and rocky outcrops along the bay’s edges, especially on the western (Point Reyes) side. From a kayak, you’ll often see just a round head bobbing in the water nearby, watching you with enormous dark eyes. They’re curious but skittish — keep your distance and let them come to you.
Elephant seals (seasonal)
From December through March, elephant seals breed and molt along the Point Reyes shoreline. You may spot them from the water, particularly near the southern end of the bay. These are massive animals — males can weigh over 4,000 pounds — and they’re best observed from well offshore. Do not approach or land near them.
Bat rays
In the warmer months, bat rays cruise the shallow waters of the bay, sometimes in groups. From a kayak, you can often see their diamond-shaped shadows gliding over the sandy bottom in water just a few feet deep. They’re graceful, quiet, and surprisingly large — wingspans of three to four feet are common.
Birds
The birding on Tomales Bay is exceptional. Brown pelicans cruise in formation just above the water’s surface. Osprey hunt from above, plunging feet-first after fish. Great blue herons stand motionless in the shallows. In fall and winter, migrating shorebirds — sandpipers, plovers, godwits — pack the mudflats. Hawks and turkey vultures ride thermals above the ridgeline. Bring binoculars if you have them.
Marine life below the surface
In clear conditions, you can see straight to the bottom in many parts of the bay. Eelgrass beds wave in the current, hosting a whole community of small fish, crabs, and invertebrates. Jellyfish pulse through the water column. Leopard sharks sometimes cruise the shallows in summer. It’s a living aquarium.
Guided Tours vs. Self-Guided
Both are great options, and the right choice depends on your experience level and what you want from the day.
Guided tours
Blue Waters Kayaking runs several tour options, from introductory two-hour paddles to full-day adventures that cover more of the bay. Their guides are naturalists as much as paddling instructors — they’ll point out wildlife you’d paddle right past, explain the geology and ecology of the bay, and take you to spots that casual paddlers might not find.
Guided tours are ideal for first-timers, families with kids, and anyone who wants to learn about the bay rather than just float on it. They also handle all the logistics — gear, safety briefing, route planning — so you just show up.
Self-guided
If you have your own kayak (or rent one) and some paddling experience, the bay is straightforward to navigate on your own. The key is understanding the wind and tidal patterns, which we’ll cover below. There are no permits required for paddling Tomales Bay, though you should respect wildlife buffer zones and be aware that some stretches of shoreline are within Point Reyes National Seashore.
A typical self-guided route from Marshall: paddle north along the eastern shore for 2–3 miles, cross to the western (Point Reyes) side where the seals haul out, then return south along that side before crossing back. This loop gives you a variety of scenery and good wildlife viewing. Allow 3–4 hours for a relaxed pace.
Best Conditions for Paddling
Time of day
Morning is the answer, every time. Tomales Bay is typically glassy calm before about 10 a.m. The northwest wind that defines the Northern California coast usually picks up by late morning and builds through the afternoon, sometimes reaching 15–20 knots by 2 or 3 p.m. This wind funnels down the bay and creates a stiff chop that turns a pleasant paddle into real work.
Plan to be on the water by 8 or 9 a.m. and off by noon. You’ll get the best conditions, the best wildlife viewing (animals are more active in the morning), and the best light for photos.
Season
You can paddle Tomales Bay year-round, but the prime season is late spring through early fall (May through October). Summer mornings are often foggy but calm, and the fog usually burns off by mid-morning to reveal a stunning day. September and October are particularly good — warm, clear, and less windy than midsummer.
Winter paddling is possible and has its own beauty — the bay is empty, the light is dramatic, and the elephant seals are in residence. But the water is colder (50–55°F), the weather less predictable, and daylight is shorter. Dress accordingly and keep your route conservative.
Tides
Tidal currents are strongest near the bay mouth (the Dillon Beach end) and mildest in the upper bay south of Marshall. If you’re launching from Lawson’s Landing, check the tide tables and avoid paddling through the mouth during strong incoming or outgoing tides. The current can run surprisingly fast through that narrow gap.
Skill Level
The bay itself is beginner-friendly. If you can sit upright in a kayak and use a paddle, you can handle Tomales Bay on a calm morning. The water is flat, the distances are manageable, and there’s always a shoreline close by if you need to pull over.
The open ocean beyond the bay mouth is intermediate to advanced. You need solid bracing skills, experience in ocean swells and currents, a reliable roll or at least a practiced wet exit and re-entry, and appropriate safety gear including a wetsuit or drysuit. Do not attempt this without ocean kayaking experience.
What to Bring
- Layers. Even in summer, mornings on the water are cool. A synthetic base layer, fleece mid-layer, and a windproof or waterproof outer layer is the standard. You’ll warm up once you start paddling, so dress so you can peel layers off.
- Dry bag. For your phone, keys, wallet, and any snacks. Water finds its way into everything in a kayak.
- Sunscreen. The reflection off the water doubles your UV exposure. Apply before you launch and bring some in your dry bag for reapplication.
- Water and snacks. Paddling is thirsty work. Bring more water than you think you’ll need.
- Hat and sunglasses with a strap. Glare off the water is intense, and you don’t want to chase your sunglasses across the bay.
- Binoculars. Optional but wonderful for seal and bird watching from a respectful distance.
- Waterproof phone case or pouch. For photos. You’ll want them.
Wildlife Rules and Respect
Tomales Bay is a protected state estuary, and the wildlife here is the reason it stays special. A few rules to follow:
- Keep at least 100 yards from marine mammals. This includes harbor seals, elephant seals, and sea lions. If a seal changes its behavior because of your presence — lifts its head, moves toward the water, vocalizes — you’re too close. Back off slowly.
- Don’t land on seal haul-out areas. The sandbars and rocky outcrops where seals rest are critical habitat. Approaching on foot can cause a stampede that injures pups.
- Respect nesting birds. In spring and summer, shorebirds nest on the sand and gravel shores. If birds are calling frantically and dive-bombing near you, you’re near a nest. Move away.
- Pack out everything. Every piece of trash, every food wrapper, every bit of fishing line. Leave the bay cleaner than you found it.
Safety
Tomales Bay is generally a safe place to paddle, but complacency is the real danger on any body of water. Keep these things in mind:
- Always wear your PFD. Not in the kayak behind you. On your body. California law requires it.
- Tell someone your plan. Where you’re launching, your intended route, and when you expect to be back. This is non-negotiable.
- Watch the fog. Fog can roll in with startling speed on Tomales Bay. One minute the bay is clear; fifteen minutes later you can’t see the opposite shore. If fog moves in, hug the shoreline and navigate by land features. A compass or GPS-enabled phone in a waterproof case is good insurance.
- Respect the wind. If the wind picks up and you’re getting pushed around, head for shore. Fighting a headwind in a kayak is exhausting, and it’s how people get into trouble.
- The water is cold. Tomales Bay water temperatures range from about 50°F in winter to 60°F in late summer. A capsize in cold water can lead to cold shock and rapid loss of dexterity. Know how to re-enter your kayak from the water, and consider a wetsuit in cooler months.
Making a Day of It
A Tomales Bay paddle pairs beautifully with the rest of what this area has to offer. Here’s a sample day: early morning paddle from Marshall, back on shore by noon, then drive north to Dillon Beach for a beach afternoon. Or combine your paddle with an oyster stop at one of the farms along Highway 1 in Marshall — you’ll drive right past them.
If you’re staying at Sea Esta in Dillon Beach, you’re perfectly positioned for this kind of day. The bay is close, the beach is closer, and there’s nothing like coming home to a comfortable house after a morning on the water.
