This large forest in the Snowdonia National Park has miles of walking paths and great mountain bike trails. There are great views towards Snowdon and a nice path around the lovely Llyn Llewellyn. The Welsh Highland Railway also runs through the forest so look out for the fine steam trains as you go.
This circular route starts from the car park just off the A4085 but you could also start from the nearby village. You can hire bikes there at Beddgelert Bikes. You can also pick up trail maps. The cycle routes are all waymarked so you can find your way easily.
The forest is also great for walkers with miles of good tracks taking you through the attractive conifer woodland.
If you'd like to continue your walking in the area then you could climb Moel Hebog or visit the stunning Aberglaslyn Pass. Both of these walks can be started from Beddgelert.
