You’re allowed to moor at any spot along the banks unless you see a sign that says, “Mooring forbidden”. Close to the village quays you’ll find mooring buoys where you can spend the night.
Aboard your boat you’ll find two anchors, but they are for emergencies such engine failure only. Lago Alqueva is manmade lake and thus there are trees and bushes on the bottom of the lake, where the anchors might get stuck.
There is a marked safety route on the lake, that is tested free of shallow areas. However, you need pay extra attention to your sonar, if you want to explore the many small islets you see in the lake. The sonar helps you watch out for shallow areas as you approach land.
If you run ashore outside of the marked safety route, you’ll need to pay in order to get towed.
The clear waters of the lake are perfect for a refreshing dip. Feel free to hop in, but while you do, keep a watchful eye on the banks, turn of engine and remove the keys from the ignition. This is to avoid accidents where swimmers get to close to the propeller. All boats have a bathing lather and a shower on the bridge.
Angling is allowed on the lake, but you need to have a license, which can be purchased at official bureaus. You can also pay the base to acquire a license for you. In that case you need to send a copy of your ID beforehand.
