Swim, Fish, and Feast —
A Day on Uguru Island

Three unforgettable experiences,
only on Uguru Island.

01

Boat Snorkeling

Head straight to the best spots by boat. With a 90%+ sea turtle encounter rate, you'll swim alongside coral reefs, tropical fish, and large pelagic species.
Beginners are welcome — we provide a full briefing on the beach beforehand.

Main Activity
02

Pier Fishing

The water is so clear you can see the fish before you catch them — an experience unique to this island.
Even beginners land fish thanks to the incredible visibility.
Your catch goes straight to lunch. All gear is included.

Optional
03

Freshly Caught Seafood Lunch

This is a special lunch experience where you can prepare and cook the fish you catch yourself. Deep-fried fresh fish is exceptionally delicious.
Even if you don't catch any fish, we offer an original curry made with squid from Sukumo, or a daily sashimi lunch. Enjoy the bounty of the sea to the fullest!

shared with our staff.
This is what the overnight plan is all about.

Frequently Asked Questions

Absolutely — in fact, non-swimmers are often the most amazed. With a life jacket and wetsuit, your body floats effortlessly. We start with a beach briefing, and guests who have never been in the ocean join us every season with no problems at all.
Children aged 1 and over are welcome. They must be accompanied by a parent or guardian at all times. Infants under 1 year old cannot participate as they are unable to wear a life jacket.
Light rain is not a problem and the tour goes ahead as planned. If the sea is rough, safety comes first and we may adjust the itinerary. Cancellations are free up to 6:00 PM the day before departure.
Yes — we have English-speaking staff and warmly welcome international guests. We can assist you in English from booking through to your departure from the island.
Just bring your swimsuit and a towel. Wetsuits, snorkels, fins, and all other gear are provided free of charge. A changing area is also available on-site.
There are no shops or vending machines on the island. If you'd like a snack, please bring one from the mainland. Lunch and drinks (beer, canned cocktails, soft drinks, etc.) are included in your plan.
