Layers

Geological value

Affects bedrock, boulder, moraine, and wind / shore layers only.

Region

Curated links to the Finnish outdoor resources that are either not mapped here, or only mapped superficially. Click "Open inline" to embed a site in the side panel; click "Open site" for a new tab.

Favourites are stored only in this browser via localStorage. They never leave your device.

To put these on a personal Google map: open Google My Maps, create a new map, click Import, and upload the KML file.

Outdoors recreation

National parks, wilderness areas and nature reserves: SYKE open data via paikkatiedot.ymparisto.fi/geoserver/inspire_ps/wfs.
Laavus, kotas, lean-to shelters and wilderness huts: laavu.org bulk GPX export (~4 500 waypoints).
Saunas in nature: Curated Google Sheet, joined by area name to the national-parks layer.

Natural sites

Archaeological sites (VARK): Museovirasto via geoserver.museovirasto.fi/geoserver/rajapinta_suojellut/wfs.
Open-air museums and ruins: Museovirasto built-heritage (RKY) + UNESCO World Heritage points via the same rajapinta_suojellut WFS.
Sacred natural sites: exported from Suomen luonnon pyhäpaikat Google Maps list.

Geological features

Caves: Luolaseura ry published WGS84 coordinates.
Climbing crags: OpenStreetMap outdoor crags via the Overpass API (filters out indoor climbing gyms).
Bedrock and cliffs / Boulder fields / Moraine formations / Wind and shore deposits: SYKE nationally valuable geological formations (four layers from the same source) via paikkatiedot.ymparisto.fi/geoserver/syke_geologisetmuodostumat/wfs. Filter by SYKE value class (1 unique, 2 extremely valuable, 3 very valuable, 4 valuable) in the Filter tab.

Wildlife

Bird-watching towers: OpenStreetMap bird hides (leisure=bird_hide) and observation towers via the Overpass API.
Bird Atlas: 4th Finnish Bird Atlas 2022-2025 via GBIF, aggregated to species richness per 10 km cell.
Butterflies (NAFI): NAFI Finnish butterfly monitoring scheme via GBIF, last three years aggregated to 10 km cells.
Bumblebees: GBIF Bombus observations in Finland since 2020, aggregated to 10 km cells.
Wolf, Bear and Lynx sightings: GBIF observations of Canis lupus, Ursus arctos and Lynx lynx in Finland since 2020, emitted as three separate layers. Coordinates are coarsened to roughly 25 km - this protects animals and reflects how far large carnivores roam.
Tick observation density: GBIF Ixodes ricinus + Ixodes persulcatus records since 2014, aggregated by maakunta. Note: this reflects observation effort as much as actual tick density.

Swimming and water

Public swimming beaches: SYKE EU Bathing Water Directive register via paikkatiedot.ymparisto.fi/geoserver/inspire_am2/wfs.
Local beaches: uimaan.fi place listings (LIPAS-backed).
Lakes: Järvi-meriwiki Semantic MediaWiki, lakes ≥ 0.5 km².
Rapids and fast water: OpenStreetMap features tagged waterway=rapids via the Overpass API (~420 named rapids).
Waterfalls: Suomen vesiputoukset, scraped from per-fall detail pages.

Quality

Live water temperature (Helsinki only): Forum Virium Uiras IoT sensors.
Recent algae observations: SYKE VESLA citizen observation database (OData), rolling 6 months.
Air quality stations: FMI air quality monitoring network (148 stations), latest AQI via the FMI open-data WFS (urban::observations::airquality::hourly::simple).
River and lake water levels: SYKE / vesi.fi via the Hydrologiarajapinta OData API; latest reading per station with 30-day median and range.
Weather warnings: FMI Common Alerting Protocol (CAP) atom feed at alerts.fmi.fi/cap/feed/atom_en-GB.xml - one marker per affected area (centroid of CAP polygon). Covers wind, thunderstorm, forest-fire, ice and other warnings up to 5 days ahead.
Pollen forecast: Open-Meteo Air Quality API sampled at each maakunta centroid; one marker per region showing today's peak per species (alder, birch, grass, mugwort, olive, ragweed).

Alcohol

Breweries: Suomen pienpanimot Google My Maps (olutkellari.blogspot.fi).
Wineries: Suomen pienpanimot Google My Maps + Viinitilat directory + personal Google Maps additions.
Distilleries: Suomen pienpanimot Google My Maps (same KML as breweries / wineries, separated by category).
