This posting does not include nmuch Visby information because there is much availble other place, It is more about the less traveled places.
My Husband and I spend a week ( June 6-13) biking around Gotland. It is a great way to see the island, and allows one to get off the tourist track. Except for the city of Visby, Gotland is flat and has little traffic so it is excellent to bike even for the flabby unfit. Many places are not open until high season or offer limited services. High season is June 20- August 31, but "high high season " is July 1 to August 15, so be sure to check operational hours. Gotland is still quite rural and be sure to pack enough water and food as there are 15-20 km stretches that have nothing but farms. Bring an air pump and at least a multi.tool if there is any question about the mechanical order of your bike. If you don't have GPS on your phone, the free map is good, but you may want to buy a better map at the tourist information center. They offer a cycling map, but it was too expensive for my blood.
From Visby to Roma on highway 143 was good most time except there was a bit of traffic that could have been better at sharing the road. There are numerous ruins and historical sites along the way to Roma. The Closter ruins and museum are nice. There is a near by train museum (http://www.gotlandstaget.se/) that is near Roma and if the train is running it will be a highligh of your trip. The coal fired steam engine pulls three cars, one from the 1870's, one from 1910 and one from 1940's. The group of train enthuasists put on a good show. I've told trip advisor about the attraction but they haven't listed it yet. The Roma Kloster ruins have a museum and cafe that is worth spending couple of hours poking around. There is a theatrical company that puts on plays durning the summer time. If you can wade through the Swedish this site has as lot of information that is not on trip advisor, http://www.guteinfo.com/?id=225 Gotland Whisky offers tours of the distillery by appointmen from June 22- August 13.
From Roma to Ljugarn on highway 143, there are many historical churches, ruins, windmills and beautiful farms.
This map gives information on cultural sites along the way www.guteinfo.com/index.asp…
Ljugarn has a long history of being a bahing resort, the beach is fairly rock free for Sweden. North from the beach is a national park with many of the rock formations you see on the travel brochures. If you are looking to chill out this is a good place to spend a few days.
From Ljugarn we biked back across the island to Klintehamn. We traveled on 144 to Hemmor and then turned north west at Garda kyrka on a paved but unnumbered road toward Etelhem. The church there is worth a stop and one can fill a water bottle at the church. From there head west towards Lostaslott here you will find a recreation of Viking long house and a good place to swim. In high season there is a cafe, and boat rental. There are ruins of a fort the are said to be the last hold out of the Gotland pirates from when the Germans had control of Gotland.
Wild horse reserve: Continuing on that road, one can vist the Lojstahedrussen reserve, the only "wild horses" in Sweden. Wild horses became extinct in the 1930's but Gotland farmers still had fairly pure blood lines so Sweden established a breeding program to re-establish the wild population. Sorry the web site is only in Swedish but there is a map with directions that work with google translate. http://lojstahedrussen.se/. On the day we were there we got to see a small herd of 6 mares and 4 foals.
This area features a nature preserve, than includes a fen area with very rare plants.
Arriving in Klinethamn we stayed at Pensionat Warfsholm, a picturesque Swedish guesthouse house, and were warmly welcomed by our hosts there. This place has bad reviews on trip advisor, but I thought it was a good value, especially for the price. The current owners have only had the place for 3 years so they have made improvements.
From there there is a bike path all the way to visby and it follows the coast line to Visby. Hogklint Naturreservat gives a stunning view of the coast line, and the uphill trip is worth the effort.
Cycling around Gotland is the way to go, even if you are only moderately fit.Edited: 25 June 2014, 12:18
