The reserve is designated as a SSSI and also, along with other areas, a SAC and Ramsar site.  The main habitat is fens but there is also heathland, woodland and small lakes.  The fen is the largest of three fens found on Anglesey.  The reserve is great for dragonflies with 21 species recorded including the rare and protected Southern Damselfly. It also has nationally scarce Scarce Blue-tailed Damselfly and locally scarce Variable Damselfly, Keeled Skimmer and Black Darter.
A boardwalk runs around the reedbeds for 1000 metres there is also a bird hide overlooking one of the lakes which can be reached via the boardwalk.  There is limited roadside parking in the village of Capel Coch.  Access is down a narrow track beside a cottage in the village.  The reserve is open all year round.  Sturdy shoes are recommended and the reserve is not accessible to wheelchairs or pushchairs.

This is another of Anglesey’s fens.  The reserve is designated as a SSSI and also, along with other areas, a SAC and Ramsar site.  This reserve is important due to its unique mire which lies in a shallow limestone valley.  There have been 15 species of dragonfly recorded here, including Scarce Blue-tailed Damselfly, Variable Damselfly, Hairy Dragonfly and Keeled Skimmer.  There are also grasshopper warblers and medicinal leeches on the site.
A boardwalk stretches for 700 metres round the site, it is prone to flooding, so wear wellington boots!  There is a small car park with space for 6 vehicles.  This is off an unclassified road between the villages of Pentraeth and Talwrn.

This is a RSPB reserve on Anglesey.  12 species of Odonata have been seen here, however this site is under-recorded for dragonflies so the total may rise.  Variable Damselfly and Hairy Dragonfly are Anglesey specialities. Valley wetlands includes Cors Crigyll, Llyn Dinam, Llyn Penrhyn, Llyn Traffwll, Llyn Treflesga and Plas Bog.  Habitats include lakes, reedbeds and a bog.
The reserve is open all year round and has well defined footpaths.  Entry to the reserve is free and there is a car park.  To get to the reserve, take the A55 from Bangor to Holyhead and come off at the junction which is signed Bodedern and Caergeiliog.  Turn left at the roundabout and head towards RAF Valley.  The reserve car park is at the far end of Lake Penrhyn (on your right), it has white posts and a RSPB logo.
