General Description
Use the drop-down menu above to view STILL photography if available - VIDEO will be shown on each "Site" page if available

A very picturesque area with an unclassified road leading around this lake. Few visitors to the lakes, ever find the back road around Thirlmere (photo a & b), (known as the West road). Thirlmere is surrounded by conifer trees running up the hillside on the unclassified road side of the Reservoir, whilst mature conifers run along the length of the Reservoir on the opposite side (main A591 road).

For those with other Interests
Coming off the A591, along the unclassified West road leading over Thirlmere Dam, are trails for dog walking, and walking up over the mountain. Keen canoeists can access the lake as per divers via the car parking areas.

Places to Stay
Guest houses and Hotel's can be found at Keswick, Grasmere and Ambleside. On the western side of Thirlmere along the unclassified West road there is also a caravan and camping site.

Try "" or alternatively check some of these links > Hotels and Guest Houses Youth Hostels for Families etc.

How to get here
From Keswick, follow the A591 towards Thirlmere. As you approach Thirlmere, a simple sign states: "Road around lake". Grab it and you'll find yourself driving on an unclassified single track road across the Thirlmere reservoir dam. (If coming from Ambleside / Grasmere end - pass the first "Road around lake" sign and take second one). Immediately over and on your right after the dam is the first of several small car parks / lay-bys offering lakeside access.

Detailed Information for Divers
Main Attraction
The Deergarth How Island holds out as being the most interesting site to dive in Thirlmere, but, this Reservoir is seldom dived and therefor remains vastly undiscovered. It's the "undiscovered country" - as Kirk and Spock might say!

Viewing Freshwater Life
Information on this reservoir, is at present, very scant. Perch, Trout, Char and Pike reside here but in smaller numbers than other natural bodies of water.
No one appears to have dived here. Perhaps this is because of the cost and permission required - see below.

Dive Planning Help
Access and use is free to all other users - only we poor, impoverished, hard-up divers have to pay (the author) but even this situation changed back in 2007. Please click link opposite fro all the details.

Sites of Special Scientific Interest (SSSI's) are around this reservoir which in themselves create restrictions, meaning you will not be allowed to dive from within areas. In many instances there is no access to the shore line from those SSSIs. Limited diving is available onThirlmere - see right side of page here >
