Summer Beach Town Business - Would Love Suggestions, Ideas, What Is Something Fun You Have Done??

I searched for similar posts but couldn't find anything.

Turns out I am going to have the summer off this year and thought it would be fun to start a small business.

-It's on the west coast of Canada, isolated and fairly small (30,000-40,000 people) mostly retirees, some families. But summer has a big influx in tourists.

-We have lots of nature - hikes, beaches, forests

-Budget-100-10,000

-Looking to do something seasonal as I should be getting back to my job in the fall or next year, but if this works out might be fun to do it every summer.

-I kinda want something just fun and positive and novel

some ideas i had were:

-walking food tour - connect with local restaraunts and stop at 5-7 places for samples and talk a bit about the town, Add a script with some really bad jokes - focus on shoulder times for business (10-11) (3-4pm)

-Ice cream bike cart. Wanted to buy an E bike anyway so could grab one and get a cooler trailer or something I could add to the front and some good music and cruise the area.

-rent out paddle boards, floating party islands. The paddle board craze seems a bit played out but I can get them for like 250 bucks used on facebook marketplace and probably rent them for 20-40 bucks an hour. Maybe buy like 4 and a big floating party island for the beach?

-Floating golf island. Sink a hole in one and win 1,000 bucks? Charge 10 bucks a ball? Bit more of a logistic challenge with getting approval for this one is my concern. I feel like the city would make it challenging to get a permit. There's also not one major beach that brings tons of people.

Local guide - I know the restaruants and hikes quite well could offer to guide people even drive them around. Not sure how to to market this, maybe facebook market place?

Something else? IS there a new novelty or trend that;s blowing up on that I could capitalize on for the summer? Thanks!
