The Foreign and Commonwealth Office (FCO) issued the advice for the whole country after protests over government austerity measures started on 3 October.
Some demonstrations became violent, especially in Quito, and led to a number of fatalities.
FCO has now lifted that advice for the majority of the country, barring Tarapoa and Cuyabeno reserves in Sucumbios, El Angel Ecological Reserve in Carchi, and all areas of Esmeraldas.
The 20km exclusion zone along the Colombian border is also still subject to the advice, except for the official border crossing town of Tulcan.
