The other interesting feature below water is the petrified trees along the west side of the lake. Most are merely tree trunks but they are massive in scale. It appears they once lined the banks of the lake but either fell or where forced into the water over time. These remains are now hard as rocks and smooth to the touch. There are 10 in all and provide for some superb abstract landscapes.
There is an abundance of vegetation throughout the lake and many small fish. The vegetation is interesting because it abruptly ends at a depth of 9-12 m (30-40 ft). Beyond that limit there is only sand and sediment which require divers to practice good buoyancy techniques to not reduce visibility. If the sediment gets stirred up, the visibility will become cloudy and requires 20 - 30 minutes to clears up. The underwater vegetation in the shallower waters consists mainly of beds of water lilies. It's a mesmerizing experience to watch as tiny gases bubbles stream upwards to the surface from these underwater fields.
Puente de Dios About an hour and a half from Media Luna is
Puente de Dios or ‘Bridge to God.’ This river and connected waterfall is another local swim/ dive site. Once you park, you will need to walk about 400 m (¼ mile) to get to the dive site. This may not seem far but it is a steep descent and more importantly a steep ascent on the way back up after your dive. There are porters that will carry your gear for tips so make sure and bring some pesos. The usual fee is 50 pesos ($5.00 US) and well worth every penny. Even not carrying your gear the hike up can be somewhat tiring so make sure and remove your wetsuit before ascending.
The dive area is fairly shallow 9 m (30 ft) but very clear. Because it is a river there is a stiff current on the surface so get below quickly. Also, make sure as you dive that you scour the river’s bottom. As mentioned, this is a local swimming hole and you might be presently surprised at what you find fallen from the pockets of careless swimmers.
