Planning a multi-day sea kayak trip on the BC coast involves more coordination than most outdoor pursuits of comparable duration. The combination of tidal timing constraints, marine weather windows, Parks Canada permit systems, and the logistics of paddling a loaded kayak in cold water creates a planning challenge that rewards detailed preparation.
This article covers the practical elements: how to estimate daily distances realistically, where to find official campsite information, how Parks Canada's reservation system works for the Broken Group Islands and Johnstone Strait area, and what to carry in terms of food and water for trips of five to ten days.
Realistic Daily Distance Planning
The most common planning error on multi-day BC coastal trips is overestimating daily paddling distances. Open-water crossing speeds for a loaded touring kayak average between 4 and 5 kilometres per hour in calm conditions. Factor in tidal current direction, and that number can drop to 2.5 km/h on the ebb or rise to 6 km/h on a favourable flood.
A useful planning assumption: budget 20 to 25 kilometres as a comfortable day in moderate conditions, with a maximum of 35 km reserved for days with flat water, favourable current, and a rested paddler. On any day that involves a narrows transit during a specific slack window, the timing of that transit effectively anchors the rest of the day's schedule.
Weather delays are routine on the exposed sections of the BC coast. The outer shores of the Broken Group Islands and the northern end of the Inside Passage regularly experience two-to-three day delays due to northwest swells or Qualicum outflow winds. Building one or two "weather days" into a ten-day itinerary is standard practice.
Campsites and Parks Canada Permits
The Broken Group Islands unit of Pacific Rim National Park Reserve contains designated camping areas at Hand, Gibraltar, Dodd, Benson, Willis, and Turret Islands, among others. These are managed by Parks Canada, and a backcountry camping permit is required for overnight stays. As of 2025, permits are booked through the Parks Canada reservation system, which opens advance bookings in January each year for the following summer season.
Demand for sites in the Broken Group during July and August exceeds supply. Booking in January — or purchasing a flexible permit that allows changes — is the standard approach for summer trips. The park also maintains a small number of sites on a walk-up (first-come, first-served) basis, but relying on these for a trip with a fixed window is risky.
Johnstone Strait and the Broughton Archipelago fall within provincial jurisdiction for most camping areas, with some sites on Crown land and others on private or First Nations territory. The BC Parks website maintains a list of designated sites with reservation requirements. The 'Namgis First Nation and 'Kwiakah First Nation hold title to portions of the Broughton Archipelago; checking with local band offices about access protocols is appropriate for any route that passes through these territories.
Water Sources and Treatment
Fresh water availability varies significantly by area. In the Broken Group Islands, stream sources are marked on NTS topographic maps, but flow rates drop considerably in July and August during dry years. Carrying sufficient water capacity to bridge between confirmed sources — typically 6 to 10 litres per person per day including cooking — is standard practice.
On the outer coast of Vancouver Island and in the northern passages, rainfall keeps creek flows more consistent, but water from coastal streams should be treated before drinking regardless of apparent clarity. Filter systems rated to remove protozoa (Giardia and Cryptosporidium) are adequate for most coastal water sources; UV pen treatments are a compact backup option.
Salt water should not be consumed. Carrying a manual desalinator as an emergency backup has been standard practice on offshore passages, but it is not a substitute for planned water logistics on a coastal trip with confirmed land-based sources.
Food Planning for Five to Ten Days
Sea kayak hatches limit the volume of food that can be carried. A standard touring kayak has approximately 90 to 130 litres of hatch volume when all other gear is packed. A food allowance of roughly 1.2 to 1.5 kg per person per day — weighted toward calorie-dense dry and dehydrated foods — covers the metabolic demand of sustained paddling in cool conditions.
Practical notes:
- Stove fuel consumption increases significantly in cold, windy coastal conditions. Budget 30% more fuel than you would for a sheltered inland trip of equal length.
- Dry bags for food storage need to be genuinely waterproof, not water-resistant. Hatches flood during capsize scenarios and in heavy breaking seas on exposed shores.
- Bear canisters or bear hang systems are required or strongly advised at most BC coastal sites. The format that works best in kayak packing is a hard canister of the type approved by Parks Canada, which fits lengthwise in a day hatch.
Notable Routes on the BC Coast
Gulf Islands: Southern Circuit
A five to seven day loop connecting Sidney, Salt Spring Island, Pender Islands, Saturna Island, and Mayne Island covers roughly 120 km depending on the route variant. This is one of the most accessible multi-day routes in BC — sheltered from Pacific swell by Vancouver Island, with established ferry connections for shuttle logistics. Tidal current management is still necessary through Active Pass and the passages between the southern Gulf Islands.
Broken Group Islands
A seven to ten day trip within the Broken Group typically covers 80 to 120 km. The exposed outer islands (Austin, Effingham, Howell) add complexity; most groups access them from the more sheltered inner cluster around Gibraltar and Dodd before committing to the outer shore on a calm-weather day. The water launch from Tofino or Ucluelet is the standard access point; a water taxi from the Broken Group Islands camp operated by Jamie's Whaling Station simplifies logistics for groups that want to avoid the initial 40-km paddle from Ucluelet in open ocean.
Johnstone Strait and Broughton Archipelago
A ten to fourteen day trip from Campbell River or Port McNeill through Johnstone Strait and into the Broughton Archipelago covers 200 to 250 km. This route passes through some of the most productive orca habitat in the world and involves significant tidal current management through Seymour Narrows, Race Passage, and the multiple channels of the Broughton. Expedition-level preparation is appropriate; the northern section in particular has limited bail-out options and variable ferry access.
Resupply Options
On trips of seven days or fewer, carrying all food from the start is straightforward. On longer trips, resupply options along the BC coast are limited. Port Hardy serves as the primary resupply point for the northern inside passage; Telegraph Cove and Alert Bay have small general stores. Tofino has full grocery access for Broken Group trips but requires a water taxi to reach mid-route.
Shipping a resupply box to a marina or lodge with confirmed package acceptance is a viable strategy for expeditions of two weeks or longer. Confirm package acceptance policies and timing in advance; several lodges along the Inside Passage can hold boxes for a small fee.
