SI: Planinsko polje je šolski primer kraškega polja, saj na eni strani izvira reka, na drugi strani pa ponikne. Samo polje je dolgo 5km in široko okoli 2,5km, po njem pa v meandrih teče reka Unica. Polje leži na 450 m nadmorske višine, ter se razteza na skoraj 11 km2 površine, ter sega v tri občine – Logatec, Postojna in Cerknica. Je najnižje ležeče polje Notranjskega podolja, katero je večkrat letno tudi poplavljeno. Voda na polje prihaja iz treh različnih virov – reke Unice, Malenščice in hudourniškega rokava reke Rak - Škratovka. Na polju pa najdemo tudi endemit kraških polj, travniška modra čebulica – Scilla (lat. Scilla litardierei) saj je to njeno najbolj severozahodno rastišče. Prav tako pa na polju, kjer gnezdijo, najdemo kosca (lat. Crex crex) (ogrožena ptica), pisano penico (lat. Sylvia nisoria), rjavega srakoperja (lat. Lanius collurio ) in vodomca (lat. Alcedo atthis). Prav zaradi teh naravnih posebnosti je Planinsko polje uvrščeno v območje Natura 2000, njegove geomorfološke posebnosti pa so naravna vrednota državnega pomena.
Ob robu Planinskega polja je nastalo tudi več naselij, največje med njimi je Planina, poleg te pa še Laze, Jakovica, Grčarevec in Liplje.

EN: Planinsko polje or Planina field is a school example of a karst field, as the river emerge on one side and sinks on the other side. The field itself is 5 km long and 2.5 km wide, and the river Unica flows through it in meanders. Field lies 450 meters above sea level and extends over an area of 11 km2. The field spreads over three municipalities – Logatec, Postojna and Cerknica. It is the lowest lying field over the system of field in the Notranjska area. Several times in a year, the filed is flooded and transformed into a lake. The water in the filed comes from three different sources – river Unica, stream Malenščica and the torrential arm of the river Rak – Škratovka. On the field we can observe endemic flower of the karst fields - Scilla litardierei - Meadow Sea bulb. This field is its northwesternmost habitat. Beside that, on Planina field we can find the corn crake (crex crex) (which is an endangered species), barred warbler (Sylvia nisoria), Red-backed shrike (Lanius collurio) and common kingfisher (Alcedo atthis). All this natural specific, the Planina field is part of Natura 2000, the geomorfological feature of the field are part of natural value of national importance.
On the edge of the field, during time emerge also some villages and settlements. The biggest among them are Planina, other are Laze, Jakovica, Grčarevec and Liplje.
This series of the caches about Planina field will take you on the sightseeing some of the specialties.

SI: Razgledni stolp na Jakoviškem griči stoji med dvema vasema Planinskega polja – Laze in Jakovico. Stolp ima razgledno ploščad na višini 4 metrov, kljub temu da je sam stolp visok 7,5 metra. Iz stolpa se nam odpre lep pogled proti južnemu delu Planinskega polja in njegove vrhove – na levi je lepo viden Stari grad, na desni pa začetek pobočja Planinske gore, del Hrušovske planote
