Boat trips

Looking to do some sort of boat day trip during the week, any suggestions please?
We did try to see if there was a boat to Tabarca from Guardamar but there were barriers at the Marina entrance and we got no further. . .
Anything local or maybe a good one via the coach firms please?
Thanks

There are plenty of boats that leave from the harbour in Santa Pola, which is just up the coast, to Tabarca. There are kiosks just opposite the boats where you can buy your tickets and they probably leave hourly.

Rosas are doing a trip to Tabarca on Saturdays. They take you to Santa Pola for the boat.

Many thanks
