The coral around Ko Bulon Le is abundant and lively. Take care while snorkelling not to scratch your chest on the reef, as in some locations the coral is at a depth of less than one meter and if the sea is a bit rough it could be dangerous.
It's possible to do some very good snorkelling in Ko Bulon Le, just a few meters from the beach.
Though the sea was a bit rough, the water was very clear and snorkelling very enjoyable.
It's a pity that the cheap underwater disposable cameras make such poor quality pics.
The warm Andaman sea has incredible turquoise and blue colours around Ko Bulon Le.
I've been here twice (once in April and once in January) and the sea was quite rough both times. I think that steady winds are quite common around here and the island becomes off limits during the monsoon seasons.
The long sandy beach on the eastern coast of the island is ideal for a nice walk on the shore. Most of the beach is backed by shady Casuarina trees, that offer a cool retreat from the peak midday heat.
The main beach of Ko Bulon Leh is located on the eastern side of the island, where most resorts are located and where the boat will drop you on arrival.
It is a long sandy beach and there are somewhere just a few rocks. In some locations the coral reef starts very close to the shore: you could walk on it (with proper shoes) but don't do it as the coral is very fragile.
We found nice small rocks around the resort, they are smooth, white and have flat bottom. If you come with children, bring along paint and brush.
