We took a bus tour with Princess. A 1.5 hour drive to the crater and only spent 30 minutes at the summit. We spent 1.5 hours at a restaurant and more time at a restroom. Again, taking a bus tour was a mistake.
We took an off road adventure into the mountains/rain forest. We saw at least 11 waterfalls and went swimming in one. The natural beauty is amazing. The people are extremely friendly and almost everyone speaks English (since we don't speak French!)
