Hi Myands,
Greeting from Peggy, Top China Travel.
Is June a good time have a hike in Longji Rice Terrace?
June can be a good time for your Longji Rice Terrace hiking since the rice were just transplanted, the terraces are filled with water, the scenery is very beautiful. And ealy June is better than the rest days in June.
Do you need 2 days hiking or just 1 day enough?
From my experience, 2 days will be better if you plan to have a hiking tour rather than a sightseeing tour. Because the morning in Longji is extremely beatiful, especially in a light rainy morning. But for 2 days hiking, a good physial condition is needed because the road may be not well and hiking level is comparative hard than a Li River hiking.
Best regards
Peggy
