Parapente
Or paraglide and recently an american has setup a school fly canoa (http://www.flycanoa.com) which offers several courses. if you don't have time or the desire for this there are also inexpensive tandem flights available so you can get a taste of flying.
An adventure company Canoa Thrills recently opened at the Surf Shak. They organize paragliding, kayaking, surf lessons and rentals, custom swell specific surf tours up and down the coast, whale watching tours, kayaking cave tours and much more. Stop by the Surf Shak and speak with the team about booking a trip.
Beachcombing along the beautiful beach at Canoa can be quite rewarding as some beautiful tropical sea shells wash up. One annoying aspect of the popularity of the beach is that, like any popular Ecuadorian beach it often has a lot of rubbish on it at the end of each day. Canoa itself is known for its ecological pride, but the rubbish is washed in from other coastal areas. You can avoid making this worse by avoiding plastic bottles. Even if you are not staying at Hotel Bambu, they will give you one free cocktail if you fill a bag up with rubbish - you can fill a bag quite quickly and it's a free drink and a great way to keep the beach clean, so everybody wins.
