Firts we did a two day, one night hike in the jungle + a stay on the campsite Nam Qua. 6 hours of hiking around the lake through pine woods as well as jungle, with some nice challenges in between, when you need to cross water. Setting up your tent, making a fire and sleeping on the shore of the lake is great. In the morning doen kayaking and a light walk back.
The day after we booked a cycling tip from Dalat to Mui Ne (instead of our already initial transfer by minibus). What a wise decision. Great cycling (climbing, downhill and flat), great views, good lunch and most import high quality bikes, helmet and gloves. And always the supporting van following, so people can easily decide to stop and step in de van, which makes it a great adventure.
Both trips we were accompanied by our tourguide Hoang Viet Linh. Proving great info about the environment, speaking English very well and taking care of safety.
