Real Madrid crushed Bayern Munich 4-0 in the semi-final second leg in Germany on Tuesday and will play either city rivals Atletico or former manager Jose Mourinho's Chelsea in the tournament decider in Lisbon on May 24.
Ronaldo now wants to follow up his Champions League final win with Manchester United in 2008 by lifting the trophy with Real in Portugal.
"It's a kind of a dream," Ronaldo told Sky Sports News. "My dream is to win the Champions League in Lisbon in my country, so we work hard, we're going to work hard to win this amazing trophy."
Ronaldo scored twice to take his tally to 16 goals in 10 games in the tournament this season, beating Lionel Messi's record of 14 in 11 matches.
He said: "It was a special moment to score 16 goals in the Champions League - it's the record, so I feel glad for that.
"But we have to appreciate to play in the final in Portugal, I think this is the most important," added Ronaldo, who does not care whether Real play Chelsea or Atletico in Lisbon.
"I don't have a preference; both of them are very strong."
Teammate Gareth Bale praised his colleague and told Sky Sports News: "That's why he's the world's best player. It's an honour to play with him and to learn from him.
"We've still got one match to go and hopefully he can score a few more goals."
Bale is enjoying a stellar first season in Madrid after his record-breaking summer move from Tottenham, with the Copa del Rey secured by his late goal and Carlo Ancelotti's men also battling for the title.
He added: "It's an amazing feeling. At the start of the season it's hard to imagine. We set out to try and win every competition we're in and we're in a great position now.
"We always have belief in ourselves. To get an early goal was very important for us to give us confidence. They were going to come at us then and we could exploit the counter-attack.
"It was a perfect game-plan for us and thankfully we got the win. I think we played a good game in both legs and we're happy to be in the final now.
"We're just focused on each and every game as it comes. We don't get carried away with ourselves too easily."
Luka Modric feels Real showed against Bayern that they are capable of going all the way.
The Croatian playmaker said: "It was an excellent performance from the start.
"When you look at both games, the first one and today, we absolutely deserved to go to the final.
"We played really good football at home and today and we scored great goals. We could have scored more, but we are really happy with this result and with our performance. We were at the top level.
"We knew what to expect from Bayern - they like to keep the ball, they like to pass the ball. But they didn't create many chances from their possession.
"They defend well when they have the ball and when we got the ball, we had great counter-attacks. Tonight we scored from two set-pieces and then after Cristiano. Overall, we performed at the top level and we deserve to be in the final."
