Nautilus Cruise or Sea Walking on Phu Quoc: Which Experience Should You Book?
6 min read
For most visitors: book the Island Speedboat Tour and Nautilus Cruise visit. It costs €32.68, runs for a full day and combines southern islands, swimming and snorkelling with the Nautilus stop. Only choose the dedicated Sea Walking Experience if the underwater walk itself is the point of the day: the listing costs €70.08, lasts three hours, but describes the underwater section itself as 15–20 minutes.
These are not two prices for the same tour. One is an island day with a stop at the Nautilus Namaste cruise; the other sells a specific underwater activity. That distinction matters because “visit Nautilus” does not mean every paid attraction there is included.
What the full-day Nautilus trip includes
The Island Speedboat Tour and Visit Nautilus Cruise has 51 reviews and 3.5 stars, against 14 reviews for the Sea Walker. Its description promises travel among Phu Quoc’s southern islands, snorkelling, swimming and views from the Nautilus Namaste cruise facility. The duration is listed as one day. At €32.68 it is priced like a budget island-hopping trip, not like a bundle containing every paid activity at Nautilus.
Treat the Nautilus call as one stop in a varied day. This suits travellers who would still be happy if the best part were snorkelling or time between islands. The listing includes hotel pick-up and drop-off (Duong Dong or An Thoi), an English-speaking guide, lunch, speedboat transfers, snorkelling equipment and flycam photos and video; water sports on the Nautilus – sea walking, parasailing, jet skiing – cost extra. Do not infer an underwater walk from photographs or from the word “Nautilus”.

What the Sea Walker ticket buys
The Red River Tours Sea Walking Experience is listed at three hours, including hotel pick-up in Duong Dong town, as a morning trip (10:30–13:30) or an afternoon trip (13:30–15:30). Its own description says the Seawalker experience takes 15–20 minutes in Phu Quoc Coral Park and refers to more than 200 coral species. The rest of the three-hour window therefore cannot be read as three hours underwater. Allow time for transport, briefing, fitting equipment and waiting your turn.
It has 14 reviews and 4.7 stars, so its rating is less informative than a heavily reviewed island tour. Its €70.08, against €32.68 for the island day, does not buy a longer day. The listing excludes children under 12, travellers over 70, pregnant women, wheelchair users, people over 127 kg and people with high blood pressure, epilepsy, seasickness, altitude sickness or nut or insect allergies; no swimming skills are needed. Ask the operator about spectacle use and whether you must climb a ladder. Free pick-up covers Duong Dong town (except The Shells Resort area); Ong Lang costs 100,000 VND per person, Cua Can and Vung Bau 200,000 VND, Bai Dai and Ganh Dau 400,000 VND, and a 20% surcharge applies on public holidays, payable on site.

Who should avoid each option?
The full-day speedboat is a poor fit if a full day of island-hopping by speedboat already sounds tiring. If the underwater walk is non-negotiable, note that on this day it is an optional activity on the Nautilus at extra cost, not part of the fare. The dedicated Sea Walker option is poor value for a confident snorkeller who mainly wants reef time: €70.08 buys a brief, structured underwater encounter, not an open-ended swim.
Neither listing supports bringing every child: the Sea Walker excludes children under 12, although it requires no swimming skills, and on the island day every water sport at the Nautilus is a separately paid extra. Get the operator’s written answer for your circumstances before paying.
Our recommendation
Choose the full-day Island Speedboat Tour and Nautilus visit for the broader day at €32.68. Pay for Sea Walking only when that underwater walk is the reason you are going, and confirm every participation condition first.
