Megaverde, speed boat trip on Tagus River

With Megaverde, check it out here, you can see Lisbon and all of the north coast up to Cascais from River Tagus and the Atlantic Ocean. With a group of 10-12 people on a speed boat it will be a true adrenaline rush experience, as they say on their website.

I have tried and it was a great experience. The sun, the wind, the adrenaline, the ocean, the laughter... and the price per person for a group of 10 is around €30 and is certainly worth it, especially for high speed lovers.
