Guiding Tidepool Walks and Seaweed Foraging Tours

How to plan, lead, and teach small-group shore tours the way Jules runs hers: safe, legal, welcoming, and honest about what the ocean is doing that day.

Six lessons on running shore tours the way Jules runs hers: reading the tide tables and marine forecast before guests do, knowing the collection rules for your exact shore, foraging seaweed legally and lightly, leading a group safely on slippery rocks, teaching at the waterline without lecturing, and the permits, insurance, and pricing underneath it all.

6 lessons · about 12 contact hours

On your own

The whole class, the practice work, and the knowledge checks. No pass score, no graded work, no certificate gate.

With Jules reading your work

Everything above, plus one real piece of work, "A complete tour plan for a real shore", that Jules reads and grades against a rubric you can see before you start. You pass at 80 percent, and you can rewrite and send it back as many times as you need. This is optional, and it is not accredited and carries no continuing education credit.

What this course covers where you live

We say plainly how well each part of the country is covered, rather than implying the whole country is written to the same depth.

If you want Jules to read your work

Everyone gets the same lessons, practice work, and knowledge checks. For $60 more you also get one real assignment that Jules reads and grades. You can see exactly how it is judged before you start, you pass at 80 percent, and you can rewrite and send it back as many times as you need. This is optional, and it is still not accredited and carries no continuing education credit.

The assignment

A complete tour plan for a real shore

Plan one full tour on a shore you can reach, from forecast to waiver.

Choose a real shore you could guide. Pull the tide prediction and marine forecast for a date you pick, and state your cancel threshold. Write the collection and harvest rules for that exact shore with the agency sources you checked, including any protected areas and protected species. Write your full pre-walk safety briefing. Describe your group size, your accessibility plan, and your teaching arc with the five species you would teach. Finish with the business page: who manages the shore and what commercial guiding requires there, your insurance and waiver approach, your price, and your weather-cancellation policy.

How it is graded

  • The day is chosen on evidence · 25 points

    Tide prediction and marine forecast are cited for a real date, and the cancel threshold is stated plainly.

  • The rules are right for that shore · 25 points

    Collection and harvest rules match the agencies that manage that shore, with sources named and checked dates given.

  • Safety and teaching are planned, not improvised · 25 points

    The briefing, group size, accessibility plan, and teaching arc are all written out.

  • The business side is honest · 25 points

    Managing agency, permit needs, insurance, waiver, price, and cancellation policy are each addressed without hand-waving.

100 points in total. You pass at 80. Jules grades what you worked out, not your formatting or your word count.

Where it can take you

Start with the naturalist class if the practice itself is new to you. Seaweed 101 and the field identification class sharpen what you can teach.

This course does not carry accreditation, credit, or continuing education units, and completing it does not count toward any outside credential. It is written to the structure a continuing education standard expects, with measured hours, written outcomes, and a completion record you can keep.
