What is this site?This site shows the tides for Lan Ha Bay, Vietnam.
In 2017, I worked as a guide for Asia Outdoors on Cat Ba, Vietnam. Among the other things we did was deep water soloing in Lan Ha bay.
I wanted to go back and climb more in 2019, but did not know what month would be the best for tides. After some looking, I found the site worldtides.info where I could get the tidal data I needed to build this site.
For most locations in Lan Ha bay, the tide is high enough to climb when it is above two meters.
Check the guidebook for details, and dive to check the landings when climbing in uknown crags.
Now go climb!
