The Ishigaki SUP/Canoe & Blue Cave Snorkeling Tour

This is the trip for travellers who want to move, not just float. You start on the Miyara River, gliding a stand-up paddleboard or kayak through a lush mangrove forest — flat, calm water that's easy for first-timers and full of birdlife and tangled roots. Then you swap the paddle for a mask and snorkel the reef at the Blue Cave, where the limestone chamber glows blue in the sun. It's rated 4.6 stars across 38 reviews, and every piece of gear is provided. Compare it with the island's other trips on our Ishigaki snorkeling tours page.

The mangrove paddle is gentle and beginner-friendly — you can choose the stability of a kayak or the fun of a SUP — and the snorkel is shallow and sheltered. Together they give you a river and a reef in a single booking, which is why it costs a little more than the beach-only trips.

Departure length and order flex with the tide, since both the mangrove river and the cave work best at certain water levels. The guide sets the timing so you get calm water for the paddle and clear water for the snorkel.

One trip, two ecosystems. Across the day you can expect:

• The Miyara River mangrove forest, paddled by SUP or kayak
• Mangrove roots, birdlife and still, glassy water
• The blue glow of the limestone cave at the right tide
• Clownfish, butterflyfish and tropical fish on the cave reef
• Bright coral in shallow, sheltered water
• A genuine mix of paddling and snorkeling in one half day

What's Included

• A guided mangrove paddle by SUP or kayak on the Miyara River
• A guided Blue Cave reef snorkel
• All equipment — board or kayak, paddle, snorkel gear and life jacket
• A safety briefing and local guiding for both activities

Not Included

• Your own swimsuit, towel and reef-safe sunscreen
• Marine shoes for the rocky cave entry
• Quick-dry clothes for the paddle section
• Gratuities for the guide (optional)

It's two activities, so plan for a bit more time and effort than a beach snorkel.

• Duration varies (2–6 hours) with the option you pick — check which you've booked
• The paddle is easy but you will get wet and use your arms; wear quick-dry clothes
• Both the river and cave depend on tide levels, so the guide sets the timing

What to pack

• Swimsuit under quick-dry clothes and a towel
• Marine shoes for the cave entry and paddling
• Reef-safe sunscreen, a hat and a secured pair of sunglasses

What to leave behind

• Anything you don't want wet — the paddle section splashes
• Any urge to touch the coral or disturb the mangrove roots

Advice from travellers who've done the trip, beyond the booking page:

• Pick the kayak if you're nervous about balance; choose the SUP for the views and a bit of a workout — both are beginner-friendly.
• The mangrove river is calmest and most reflective early or at higher tide; ask which slot suits the day.
• Wear quick-dry clothes and secure your sunglasses with a strap — you'll be paddling and snorkeling.
• Marine shoes earn their keep here: you use them on the paddle launch and the rocky cave entry.
• Confirm your exact duration when booking — the same tour runs as a short half-day or a longer combo.
• A rash guard covers you from sun on the open river and habu jellyfish on the reef in summer.

This is the pick if you want an active half day mixing calm-water paddling with reef snorkeling.

• Active travellers who want more than a beach swim
• Couples and friends after a river-and-reef combo
• Beginners happy to try SUP or kayak on flat water
• Nature-lovers keen on the mangrove forest as well as the coral

Not ideal for

• Travellers who only want to snorkel and skip the paddle
• Anyone with limited mobility or shoulder issues (paddling is required)
• Visitors wanting the cheapest, shortest trip on the island
