Review#The Best Penghu Diving Packages
For this Penghu Diving boat trip, Ariel chose Langyu Qianxing's half-dive, half-land tour. With six guests, including Ariel, there were an impressive four accompanying instructors, clearly showing the venue's strong emphasis on safety!
The first stop was the famous Lavender Forest dive site, where guests could choose their preferred activity: mermaid experience, snorkeling, water propulsion, or SUP. Ariel highly recommends starting with the mermaid experience, as it's a great chance to take beautiful photos in a mermaid costume before getting wet and disheveled. They even have suitable sizes for children.
The instructors are not only excellent photographers, but they also carry multiple GoPros both on the boat and underwater, ensuring no exciting moment is missed. Even those without diving experience can feel at ease, as instructors are always on hand to guide and demonstrate.
For lunch, Langyu Qianxing even specially prepared SUP submarine sandwiches, showing attention to every detail, even meals.

Final Thoughts
This concludes our Penghu Diving recommendations, based on Twosevenths' mystery shoppers personally experiencing six different Penghu scuba diving and freediving venues.
Each Penghu dive venue has its own unique characteristics and specializes in different scuba diving certification courses. On your next visit to Penghu, be sure to set aside at least half a day to fully immerse yourself in the ocean's embrace! However, it's crucial to remember to avoid flying within 24 hours after scuba diving to prevent decompression sickness. Plan your Penghu Diving activities carefully to avoid scheduling them immediately before or after your flights.
