Visited with a Finnish friend.It is a beautiful setting on Lake Tuusala but you will need transport.Beautifully laid out museum showing the work done by woman during the wars It was laid out along the lines of a military service and really combined the work of the UK Land Army,Red Cross,WRVS alongside Nursing,Childcare,Sewing Clothing,and Catering with Fire Watch and Plane Spotting for bombing raids.
Well documented, in English too and the staff are very helpful.
Great cafe ,enjoyed lunch and they have cakes and Pastries too and a small gift shop.
Beautifully clean, mobility friendly.
The scenery and the lake itself are well worth a visit.

Lotta Svärd Museum is owned by Lotta Svärd Foundation. It is located in Tuusula around 30 km from Helsinki Center. Easiest to go by own car. It is composed of the museum, museum shop and a cafe. Really worthwhile to visit. The museum is small but a lot of opportunity to use all your senses. Nice surroundings.
In the Tuusulajärvi area and along the old road there are several interesting destinations to visit like Ainola (Sibelius), Ahola (Juhani Aho, Venny Soldan-Brofelt), Halosenniemi (Halonen), Erkkola etc.

Lotta Museum is located beside lake Tuusula. at autumn there is a festival taking place on Järvitie of Tuusula, when Lotta Museum is organizing buffet to everyone. As well there is many other happening on same road same time. Other good timing is come at Finnish Mid Summer Festival.
On these times or ote times when Lotta Museum is open, you will have splendid service and enjoy their cafeteria.
If you like cycling, there is excellent 20 kilometers circle to cycle around lake of Tuusula and plan to have an one stop at Lotta museum. There are more places to have other stops.
If you arrive at winter time you can take skies instead of bicycle and enjoy skiing on ice around of lake.
